If the weld is supposed to be on all four sides, what symbol will be used?
Circle
What is the stress term called that has the narrow dimension carrying the load withe the fibers at the top in compression and the bottom fibers are in tension?
Extreme Fiber Bending (F)
Most structures consist of both structural steel and reinforced concrete?
True
Reinforced concrete in that the steel reinforcement is used to provide steel’s_______ strength capacity to a structural concrete member.
Tensile
Assume you have a steal beam that is 20 feel long and carries a concentrated load of 500 pounds at a distance of 15 feet from reaction (R). Reaction (R) is pinned 5 feet from the load. What are the values in lbs for R and R?
375 and 125
(50015)/20 =375
(5005)/20=125
