NON-LINEAR BEHAVIOR ANALYSIS OF RC FRAME STRUCTURE CONSIDERING SHEAR DEFORMATION OF JOINT

Abstract

Two dimensional non-linear analysis of reinforced-concrete frame structure considering shear behavior of joint panel is presented in the paper. Inelastic joint shear action under reversed-cyclic loadings is complicated: interaction between shear deformation of joint panel and bond failure of longitudinal reinforcements embedded in the joint. The purpose of the research is to propose a simple beam-column joint model to predict such a behavior of a joint panel. A finite element formulation of fiber beam/column elements, new joint element considering shear deformation and material model defined in analysis are presented. Simulation analyses for three different type beam-column joint specimens are conducted to confirm the validity of the proposed method.
