Nonlinear FEM Analysis of RC Staggered Joint by Using APDL Language[J]. Journal of Civil and Environmental Engineering, 2006, 28(1): 74-79. DOI: 10.11835/j.issn.1674-4764.2006.01.019.
In order to settle some problems involved in applying ANSYS into nonlinear Finite Element Analysis of RC structure
this paper discusses the nonlinear FEM method for staggered joint
incorporating its experimental result.The main solved problems are as follows:(1) The fundamental process of nonlinear FEM analysis;(2) How to model the behaviors of reinforcement and concrete respectively;(3) How to model the bond-slip relationship between reinforcement and concrete.
