Roof Truss Experiment Lab Report

Statics design bridge report course outline.

Roof truss experiment lab report.

For this purpose two of the four aluminum made trusses namely warren truss and pratt truss are analyzed first experimentally and than theoretically. In class wednesday 11 26 08 overview a three dimensional truss is tested under transverse loading and the load deflection characteristics and the internal bar member strains are measured. The application of truss also can be apply in the roof construction. You will choose one of the strain gages and use the p 3500 strain indicator to measure the strain.

Set loads were applied to the structure and used to determine the axial forces in various members of the truss throughout the course of the experiment and. What you will do in the lab. In short span 8 12 m roof trusses the member forces are smaller. The thickness of the gusset is in the range of 8 mm to 12 mm in the case of roof trusses and it can be as high as 22 mm in the case of bridge trusses.

The instructions to set up the strain gage are given on the p3500 box. A truss is a common and basic design in bridge structures. 1 0 objective of the experiment 2 2 0 learning outcome 2 3 0 theory 2 4 0. The truss in class session.

The design of gussets is usually by rule of thumb. You will apply the load at the center of the truss as shown and record the strain. Lab report for engineering lab 2. Truss structures lab report abstract this experiment involved the creation of a warren truss bridge in an attempt to experimentally validate the mathematical methods commonly used to theoretically evaluate structural stability and integrity.
