STEM Walkway Design Challenge – STEM I

 

The Scenario – The senior partners (STEM course teachers) of the L&N Architectural Firm have been assigned the challenge of designing a covered walkway to the junior partners (STEM students) in the firm. Junior partners will work in design teams of 4-5 members and will research, design, create and present their work to the senior partners for their review.

The Objective – Design an architecturally relevant railway style bridge that will serve as a walkway from the L&N building to the Depot. The bridge must fit into the overall aesthetics of the L&N site and meet all technical requirements as established by the senior partners.

The Components – each of the following areas need to be completed by your design team.

  1. Research – minimum of 5 images of relevant railroad bridges, design elements and requirements for constructing a railroad bridge, historical features of railroad bridges in the east Tennessee region, your research must define the following essential architectural and engineering terms (load, force, span, bridge deck, through truss, deck truss, tensile strength, compressive strength, buckling, carbon steel, high-strength low-alloy steel, quenched and tempered low-alloy steel, hollow tube structures, solid bar structures, yield stress, failure, moment of inertia, modulus of elasticity, deck elevation)
  2. Empathy – external expert presentations, prepare 2 essential questions to ask a presenting expert, interview a principal, faculty member and/or other students for what elements they wish to see in the STEM walkway
  3. Ideation – summarize research into possible solutions and designs, create a design plan that must be signed off by a senior partner
  4. Design – create and test sample bridges using West Point Bridge Design software, designs should be accurate and reflect intended design elements
  5. Prototype – design teams will create a cross section of their desired walkway solution that can withstand a sample test without being destroyed, please attach the image of your 5 researched images to the prototype materials that most represents your solution
  6. Summary Presentation – students will create a trifold portfolio that will serve as a summary presentation for the project, the three parts to be addressed – research, design and project analysis

 

The Roles – each design team should plan to fulfill the following roles with the expectation that each member of the design team will participate in every phase of the project

  1. Researcher – this person is responsible for leading the design team’s efforts to complete all research items listed above and selecting the 2 questions that will be asked of the presenting experts, be sure to delegate roles appropriately (need interviewers, image collectors, etc.)
  2. Planner – this person is responsible for leading the design team’s efforts in completing a relevant and feasible design plan for creating the selected walkway design
  3. Design Leader – this person is responsible for leading the design team’s efforts on the West Point Bridge Design software, i.e. – the person on the computer during software simulations and analysis
  4. Foreman – this person is responsible for leading the design team’s efforts in creating their testable cross section and will be the main design team representative during testing
  5. Chief Presenter – this person is responsible for leading the design team’s efforts in generating their trifold portfolio and its overall quality, this person will also serve as the main presenter of the portfolio to the senior partners

 

WALKWAY PROJECT RESEARCH:

Research – minimum of 5 images of relevant railroad bridges, design elements and requirements for constructing a railroad bridge, historical features of railroad bridges in the east Tennessee region, your research must define the following essential architectural and engineering terms (load, force, span, bridge deck, through truss, deck truss, tensile strength, compressive strength, buckling, carbon steel, high-strength low-alloy steel, quenched and tempered low-alloy steel, hollow tube structures, solid bar structures, yield stress, failure, moment of inertia, modulus of elasticity, deck elevation)

 

WALKWAY POSTER PRESENTATIONS CHECKLIST:

– A title

– Names of all group members.

– 5 images of bridges/walkways that inspired your group’s design

– A brief caption about each image (location of bridge, type of bridge, etc).

– Your 2 expert questions WITH answers. (Research to find the answers online if you did not ask your questions during the expert’s presentation).

– Your POV statements.

– Your original bridge design (on grid paper)

– A GOOD photo of your basswood prototype.

– Your bridge schematic from WPBD.

– A 3D image of your bridge from WPBD.

– All major revisions to your bridge design… Document that you tested and revised your prototypes.

– A 200 word description of how your group applied all 5 steps of the d.School design process to design the walkway.
