3 cards from this section. Quick, good the night before a test.
What is a dead load?
Think about what is permanently part of the structure.
Name one type of truss.
Recall the trusses we discussed in class.
Which type of load does the self-weight of the roof fall under?
Think about what is permanently part of the roofing system.
True or False: Wind loads always act to compress truss members.
Consider the direction of wind forces on structures.
A Pratt truss spans 10 meters and must support a live load of 2 kN/m² and a dead load of 1 kN/m². Calculate the forces in the top chord and bottom chord members. Assume uniform load distribution.
Start by calculating total loads before analyzing member forces.
Design a Warren truss to support a shaded area with a snow load of 3 kN/m². Identify the dimensions and configurations of the truss members and evaluate for safety against wind uplift.
Consider wind effect on the truss members within your design.
