Abstract:
Nonlinear finite element analyses of RC beam-column joint specimens that exhibit shear failure under cyclic lateral loading were conducted to investigate their fracture modes and post-peak behavior. Response mechanisms such as cyclic deterioration and shear resistance were investigated. In performing the analyses, spatial discretization, modeling of bond behavior and the type of loading were considered. The macro-scale model for predicting the joint capacity proposed by Shiohara is reviewed and the validity of his hypotheses are rigorously investigated through comparison of the observed and calculated results.
