Shear Strength of Beam-Column Joints with High-Strength Materials

Abstract

The state-of-the-art on recent experimental research in Japan on beam-column joints with high-strength materials subjected to seismic loads is introduced. Previous experimental studies on beam-column joints in reinforced concrete frames for seismic resistance is outlined for the shear strength of beam-column joints and the deformation characteristics of subassemblages including beam-column joints. Analytical research using FEM microscopic models and macroscopic models have been done in order to deepen the understanding of the experimental results and to investigate the shear resisting mechanisms of the joints with high-strength materials. Recent analytical research on joints using the high-strength materials is introduced.
