    Professional Engineer:
    General Description of Role
    Professional Engineers are required to take responsibility for engineering projects and programs in the most far-reaching sense. This includes the reliable functioning of all materials, components, sub-systems and technologies used; their integration to form a complete, sustainable and self-consistent system; and all interactions between the technical system and the context within which it functions. The latter includes understanding the requirements of clients, wide ranging stakeholders and of society as a whole; working to optimise social, environmental and economic outcomes over the full lifetime of the engineering product or program; interacting effectively with other disciplines, professions and people; and ensuring that the engineering contribution is properly integrated into the totality of the undertaking. Professional Engineers are responsible for interpreting technological possibilities to society, business and government; and for ensuring as far as possible that policy decisions are properly informed by such possibilities and consequences, and that costs, risks and limitations are properly understood as the desirable outcomes.
    Professional Engineers are responsible for bringing knowledge to bear from multiple sources to develop solutions to complex problems and issues, for ensuring that technical and non-technical considerations are properly integrated, and for managing risk as well as sustainability issues. While the outcomes of engineering have physical forms, the work of Professional Engineers is predominantly intellectual in nature. In a technical sense, Professional Engineers are primarily concerned with the advancement of technologies and with the development of new technologies and their applications through innovation, creativity and change. Professional Engineers may conduct research concerned with advancing the science of engineering and with developing new principles and technologies within a broad engineering discipline. Alternatively, they may contribute to continual improvement in the practice of engineering, and in devising and updating the codes and standards that govern it.
    Professional Engineers have a particular responsibility for ensuring that all aspects of a project are soundly based in theory and fundamental principle, and for understanding clearly how new developments relate to established practice and experience and to other disciplines with which they may interact. One hallmark of a professional is the capacity to break new ground in an informed, responsible and sustainable fashion.
    Professional Engineers may lead or manage teams appropriate to these activities, and may establish their own companies or move into senior management roles in engineering and related enterprises.

CE.3 Career episode 3: Planning, Analysis and design of the trussed roofing system for the existing structural engineering laboratory incorporating bio-mimicry in shape

CE.3.1 Introduction

This career episode is based on the planning, analysis, and design of the trussed roofing system for the existing structural engineering laboratory incorporating biomimicry in shape project presented to the SRM University, Department of civil engineering, Kanchipuram in May 2016. The project undertaken by four group members was carried out as part of a bachelor’s degree in civil engineering under the supervision of the department head Dr. K.S Satyanarayanan. As part of the project team, I was tasked with the analysis and design of the bio-mimicry tie members to carry out the same purpose as the conventional tie members.

CE.3.2 Background

CE.3.2.1 Overview of the project

The designed roofing of the university Engineering laboratory was meant to provide sufficient daylight natural lighting and shield from adverse weather conditions such as heavy rainfall, violent winds, or scorching heat from the sun to name a few. The bio-mimicked truss should be able to fulfill the technical mandate while at the same time appealing to the eyes. This project involves the incorporation of bio-mimicry shape in structural tie member development. By biomimicry, the tie members were meant to adopt the structurally viable human hand bone form. The engineering laboratory is a large building which implies that the truss framework must be able to cover a long span. Besides, the engineering laboratory requires long free column space for machine and equipment movement hence the need for trussed roofing. In this project, the analysis and design of traditional truss frameworks and the bio-mimicked framework was compared, also for their feasibility and efficiencies. Bio-mimicry tie members provided a design that overcame the presumed economic constraint by proving economically viable structures than the traditional framework. Similarly, the bio-mimicked framework increases the truss stability hence overcoming the manufacturing constraints to produce highly safe trusses. By developing elements with structural efficiency, construction cement demand was reduced and the economy of construction improved. Adopting nature compliant designs enhanced the aesthetic value (appeal to the eye) of the tie elements. The project utilized ANSYS v12, AutoCAD 2014, and STAAD. Pro v8i software to ensure the expected outcomes were achieved. An intense literature review was conducted to support the biomimicry use in architecture and achieve sustainability in building design models. Once the truss type chosen, a manual analysis of roof was carried out and materials with high yielding stress were selected. 

CE.3.2.2 Project Objectives

The project objectives include:

  • To propose an RC truss system for existing structural engineering laboratory and analyze the proposed truss system following the IS code for wind load, live load, and dead load conditions.
  • To undertake the design of the conventional truss system specified above simultaneously with the design of foundation and column components.
  • To arrive at the biomimicry shape of tie members based on the human hand bone shape.
  • To compare module costs for both truss framework options.

CE.3.2.3 Statement of my duties

I was tasked with the design of the biomimicry tie member based on information derived in the design of the conventional tie member. The project task was ingenious and innovative. I had to ensure that the bio-mimicked members developed could effectively serve structural and aesthetic purposes while attaining safety and economic efficiency. As the team members were assigned with the design of the bio-mimicked tie member, I was responsible for determining and documenting required materials that could withstand equal loads to ones obtained in the conventional truss system analysis and design. In addition, I was assigned with carrying out the actual software design and development of a suitable bio mimicked structure using the conventional tie member dimensions and then generate a cost comparison.

CE.3.2.4 Organization Structure

The organizational chart was a top-down structure. The project was directly under the guidance of the civil engineering head of the department. It comprised the university, department head, supervisors, team leader, and team members as shown in figure 1 below.

CE.3.3 Personal Engineering Activity

My knowledge of systems analysis was fundamental in determining how the biomimicry truss system should work. I was also able to establish the effects of environmental, operations, and conditional variations on the project outcomes. Knowledge of engineering mathematical concepts such as statistics, calculus, geometry, algebra, and arithmetic was essentially applied in calculating the loads, stresses, and dimensions required to design a strong biomimicry truss system. Similarly, I applied knowledge and prediction of the physical laws and principles and their applications and interrelationships to understand the atmospheric, material and fluid dynamics and sub-atomic, atomic, and mechanical structures. Reverse engineering knowledge and skills also enabled me to extract design information from the traditional truss system design specification that I used to reproduce the bio-mimicry tie members. I applied structural analysis and design principles to ensure the bio-mimicry structure met the building code and standard practices. I also applied engineering design principles to establish the features required to achieve a truss member of high aesthetic value. Principles of expansion and contraction and load analysis were also fundamental in ensuring the truss member was designed to withstand various environmental conditions. Material science knowledge was crucial in determining the material used for various components of the bio-mimicry truss member. I applied knowledge of flexible manufacturing systems to determine the design characteristics that will allow free movement of machines within the laboratory while complying with various safety standards and regulations.

CE.3.3.1 My assigned task was to use the knowledge obtained from the traditional truss system to develop a bio-mimicked truss system of similar configurations. To carry out this task, I started with identifying the design problem which was to incorporate nature into structural analysis and design. This was followed by searching for biological analogies that could be used to resolve the design problem. For truss tie members, I identified the human hand analogy the ultimate design consideration suitable for the structure. I then identified the appropriate structural and mechanical principles required to achieve this design. I used the ANSYS v12 to develop the smoothing algorithm from a set of single patches while preserving the structural complexity and curvature of the tie members. The bio-mimicked tie member using ANSYS v12 is shown in Figure 2. I used STAAD Pro to calculate the load acting on the biomimicry tie member and compared the obtained values with those from the conventional tie members. The software was also used to evaluate the maximum tensile stress and strains acting along with the line elements on each truss beam as shown in Figure 3 and Figure 4.

CE.3.3.2 Analysis and Design of the tie member

One of the major problems I encountered during the project was to design a bio-mimicked truss system whose truss span to depth ratio was sufficient to avoid deflection. Compared to the normal beam ratio, this ratio was considered low because a high span: depth ratio causes deflection. This is specifically a challenge because parts of the biomimicry tie members should be held firm using bolted joints causing slippage when joints are loaded. To overcome this challenge, I opted for welded joints with high strength bolts or split ring connectors that could function well under friction. The design also incorporated allowance for shortening and lengthening due to internal compression and tension forces. The other technical problem was the issue of secondary stresses induced in the truss members by other factors save from axial forces. Axial forces are accounted in the analysis of the pure truss pin-jointed actions such as continuous members, member stiffness, joint rigidity, and joint deformation. I predicted possible secondary stress effects to occur under quite stiff members or quite rigid joints conditions. I also expected the secondary stress effects where truss members were quite short and stout and where truss members were slender such that the joints can only manage the medium transfer of moments to the end to the tie members. I overcame this challenge by using the software to design accurately measured joints and tie member dimensions. This ensured that all design specifications were optimal to accommodate both primary and secondary stress effects.

CE.3.3.3 Estimate and Cost comparison

During this project, I designed an original biomimicry truss system tailored to meet the engineering laboratory needs. To achieve this objective, I employed a total accuracy strategy. For this strategy, I used theoretical and computational mechanics to analyze the compatibility, equilibrium, and constitution of the structure. I also used the basic principles of finite element method to calculate the reaction forces under the hinged support of the bio-mimicked tie member as shown in figure 1 below.

While recognizing that the truss system was meant to support high-cost machines and people working with them, I laid special emphasis on safety and effectiveness. Therefore, I employed the strategy of ensuring every design characteristic were observed and incorporated not forgetting the economic, safety, and environmental considerations. To ensure the traditional and bio-mimicked truss systems were fully compared for functionality, aesthetic and economic features, I made identical tables in which various characteristics were entered. This strategy makes it easy for the reader to point out differences and similarities between the two systems. Once the design requirements were established, I carried out the cost estimates to produce a bio-mimicry truss including the cost implications on materials, labor work, and other operational requirements. This step was requisite to ensure that the design of the biomimicry tie members favors infrastructure sustainability as directed by the UN sustainability framework that has grown into a global environmental, social and economic standard. The cost estimation of both conventional and bio mimicked tie member was done as shown in tables 1 and 2 below which depicts the economical advantage of the bio mimicked tie. The dimensions of the structures mentioned in the table were developed from the design coursework incorporated with IS Standards. Using STAAD Pro the maximum tensile load acting on the beams of both the tie members were calculated along with the wind load and live loads acting on the structure to formulate the design and then compare the costs of materials required. To evaluate the difference in acting forces between the bio-mimicry and the traditional members required in the cost estimation procedure, their respective areas must be determined using axial stiffness as in the illustrations below. Once the areas were established, I used the STAAD software to calculate the tensile forces acting on each beam

For the conventional tie member:

Axial stiffness of tie member.

K =(A×E)/𝐿(5.1)

L (length of tie member) = 185.92 mm

A (area of tie member) = 185.92 × 25.8 (5.2)

= 4796.26 mm2

For the biomimicry member:

Kbone = 1/ (1.0197 × 10−6 × 10−3) = 980.68 kN/mm

Now,

K =(A×E)/𝐿

980.68 = (A ×17.2 ×106)/323

A = 184.16 cm2

We shall take equal angle section, back to back.

Take ISA 200 × 200 × 25 @ 187 cm2

Abstract comparison of cost for both the structures are shown in Table 3 proves that bio mimicked tie member has an economy of 0.067%. This analysis established that the cost of producing a bio mimicked tie member was 1.067 times lower than that of the traditional tie member.

CE.3.3.4 The project operations emphasized the need for a well-collaborated team. As part of the team, I ensured that team members understood the part of the project under my responsibility by updating the progress constantly. Besides, I consulted my team members and the supervisors whenever an analysis area presented an expected challenge. This enabled us to successfully achieve the goal of designing an optimally functional biomimicry truss system for the engineering laboratory which would have been impossible with an improperly coordinated team.  Teamwork also exposed me to new techniques of truss system analysis and design. While using the software, I learned various shortcut commands that could directly achieve similar outcomes with the long chain of commands I knew. Therefore, teamwork improved my proficiency level of operating with three main software.

After the analysis and design of the conventional tie member, the bio-mimicked tie member designed using ANSYS enabled analyse the stress and strain forces on the bio-mimicked tie member. The load calculation was carried out for both the tie member which was tabulated and the beam with maximum tensile forces acting on both the structures were pointed out. The tensile force acting on the bio-mimicked tie member beam was 8.5% more than that of the conventional tie member. The tie member with the maximum tensile force was chosen for replacement with the bio-mimicked tie member.

CE.3.4 Summary

The project successfully exploited and analyzed the feasibility of the bio-mimicked truss framework concept. Besides, the goal to plan, analyze, and design a biomimicry truss framework was accomplished with proper load, stress, strain, and material analysis. The project also successfully compared the traditional and bio-mimicked design features and established that the bio-mimicked framework overcame the economical and aesthetic challenges common with truss systems. My role to analyze and design the biomimicry truss system contributed to the project’s success because it gave the truss framework a touch of nature. By conducting collaborative analysis with various consultations from biotechnology professionals, I along with my teammates was able to drive the project to its ultimate success.
