z Workshop Objectivesz Build a truss model and analyze it. Determine the maximum
displacement and stresses. Is your design better than the arched-roof truss design presented in the Case Study?
z Visualize the load path in the truss by plotting the rod elementaxial stresses. Follow the load from the load application point to the fixed base. Do the stresses make sense to you?
z Become familiar with the .f06 file

z Problem Descriptionz Three truss designs are presented on the following pages. Select
one design and analyze it.z The truss is made from steel with E = 30 x 106 psi and = 0.3.z The cross-sectional area is A = 4.516 in2.z The torsional constant is 37.398 in4.z A 500-lb point load is applied at (60,168,0).z The truss is bolted down at the Y=0 boundary.z Model the truss with rod elements.
