Thank you to Pinehurst, dik, and dbuzz. The leakage problems identified by Pinehurst was something I had not considered. This project is a design-build project and the contractor has already determined that the precast option costs $500,000.00 less than the post-tensioned option. Thanks Dik...

I have to generate a letter to a state university system comparing the advantages and disadvantages of post-tensioned cast-in-place parking garages vs. pre-cast parking garages. The purpose of the letter is to facilitate the university in choosing one of the two systems for a new 630 space...

faisal25 I agree with GraemeL. The relative stiffnes of the shear walls and moment frames should determine how lateral loads are distributed to the individual elements. On a recent 18 story concrete structure in a 140 mph wind zone, I utilized RISA 3D to model the structure and found load...

I'm reponsible for designing an enclosed and air conditioned bridge connecting two academic buildings at a 45 degree angle to each facade. The walls of the bridge are all glass. The structure is composed of two vierendeel trusses spanning 61 feet between freestanding 32-foot tall concrete...
