Structures Walk-About

The Problem
The problem is to identify truss systems and elements that can be found in our surrounding environment.

The Objectives
The objectives of this exercise are to reinforce the notions:

• that structures are an everyday part of our lives.
• that structural concepts can be simply visualized and understood.
• that sketching is a critical skill of every designer

The Rules
The only material that can be used for this exercise is postcard sized (4" x 6") white or off-white card stock. The sketches should be lucid with the free-body diagram clearly indicated on the same side as the sketched image. A written verbal description of the structural system, structural element and/or any unique characteristics that are observed should be included on the reverse side of each card.

The Process
A stroll will be made with your lab section around the campus. Draw at least one truss system as you stop along the way. These can be discussed with your TA.

The Documentation
Ten postcards should be completed by the end of the walk and immediatly submitted.

The Evaluation
The evaluation will be based upon the clarity and degree of completion of the postcards. It will also depend upon the accuracy of the free-body diagrams and the lucid description of each of the truss systems.
