When we design a concrete pilecap there are two approaches: Consider it as grillage of beam or deep beam or consider as a strut model. But regardless of the method, we provide the reinforcement as uniformly distributed along the whole length/breadth of the pile cap.
My question is: Can we...
Dear Pujan, I am afraid you will never get any answer here. The first thing is if you dont know about the Finite Element Method (FEM), then dont use SAP or any other FEA software. If you have the concept of FEM then first you must learn from someone or from the manuals and tutorials.
Thank you guys. In my post i presented a simple arbitrary model to make my case clear. In reality there are multiple lanes and moving loads with different eccentricity. And of course the deck slab is also there. I am still checking my models and i feel more confident in my analysis after your...
I posted this matter in another forum Computers and Structures: SAP2000. Until now cant get any response so i am posting here again.
Traditionally the lateral load distribution on bridge deck girders are done by different semi imperical methods mainly based on lever theory. By such methods most...
Sorry, i missed some information. The response of the longitudinal girders varies according to the stiffness of the diaphragm and spacing of the girders.
While analysing for monolithic RCC slab-on-girders bridges by SAP2000, I got some strange results. For simplicity Lets take an example as follows:
Bridge span = 25 m
Number of longitudinal girders = 3
Number of cross girders (diaphragms) = 6 including end diaphragms
Spacing of logitudinals =...
