이방향 하중을 받는 모서리 보-기둥 접합부의 내진성능 평가

Abstract

In this study, two full-scale gravity load-designed reinforced concrete corner beam-column joints were tested by being subjected to uni- and bi-directional cyclic lateral loading. The test variable was loading type: uni- or bi-directional loading. To investigate the effect of the loading type on the cyclic behavior of joint specimens, damage progression, force-deformation relation, contribution of joint deformation to total drift, joint stress-strain response, and cumulative energy dissipation were investigated. The test data suggest that bidirectional loading can amplify damage accumulation in the joint region.
