For the statically determinate steel truss shown in the figure, it is required that you perform structural analysis of the truss and then design the following truss members in accordance to whether it is a tension member or a compression member: members CA, CD, and DA. The loads shown on the figure are factored loads. All truss elements should have a W12-shaped cross-section. Assume that all members will be connected to the web only using two lines of bolts in the direction of the load, with each line containing 5 bolts of diameter 6/8 inch. Use A992 steel for all members. Do not skip any shape when designing your truss members. Check all possible limit states according to what we discussed in class. Show your final results in a table listing each member and the cross-section that you selected for it. When you compare the cross-sections selected for tension members and those selected for compression members, what are you conclusions? (some points will be assigned to assess your conclusions). 300 kips В. C 30 ft D етете А -20 ft 20 ft 200 kips
