Nonlinear FE Analysis for RC-Column and S-Beam Joint Using High Strength Rebar

Abstract

Structural method to join RC-column and S-beam without the S-beam penetrating the RC-column has been developed by use of high strength rebars. FE analyses are conducted for a variety of previous test specimens to investigate the applicability of the analysis for the structural method. It is found that FE analysis can reproduce the nonlinear behaviors of the test specimens. Furthermore, Numerical studies by FE analysis are performed to evaluate structural performance of exterior side joint under tensile axal force and interior joint with steps in beam.
