To start, I understand the need for minimum reinforcement requirements to prevent the failure of beams without warning. However, the requirements of AASHTO seem onerous. Using a stiffer section with ample prestressing increases the cracking moment, penalizing the design in the process. The...

Also, I am looking for a copy of "Handling...
I'm looking at a U-bolt that has been bent from A36 rod. It will be loaded in such a way as to produce both tension in the legs and moment in the bend. Does anyone know of a reference that would help me estimate the residual stress in the bend? I plan to stay in the elastic range with a healthy...
