concrete slab – Non-Linear Behavior - Post-Tensioned - The numerical treatment. |
| |
In this research, a nonlinear finite element model developed to investigated the behavior and ultimate load capacity of unbonded post-tensioned one-way concrete slab panel. The numerical treatment adopted by finite elementANSYS software has been carried out on two different one-way concrete slabs chosen from previous available experimental study in order to evaluatetheir results.Mode of failure and the load-deflection relationship are presented for two cases. A parametric study was conducted to study the effects on the global structural behavior due to the effect of concrete compressive strength, effect of effective prestressing stress, effect of prestressing (post-tensioning) technique, types of loading, effect of tendon profile, effect of tendon bonding, effect of span to depth ratio of concrete slabs. |
