Design of Nonlinear Finite Element Analysis Program for FRP Rebar Reinforced Concrete Two-ways Slab
摘要
Abstract
Based on the 3D 20-node isoparametric element and integral finite element model, the nonlinear finite element analysis of the cracking and punching shear capacity of FRP rebar reinforced concrete two-ways slab subjected to concentrated load is carried out. E-v full dose model in the nonlinear elastic theory for the concrete constitutive relation, is adopted. Improved Ottosen 4-parameter formula for the concrete failure criterion and the smeared crack model are adopted when compiling the FEM program. The comparative results show that the nonlinear finite element analysis results correspond with experimental data well, and the FEM program proposed can effectively simulate the test process of FRP rebar reinforced concrete two-ways slab.关键词
