ASSESSMENT ON EVALUATION OF OUT-OF-PLANE SHEAR STRENGTH OF REINFORCED CONCRETE PLATE SEISMIC-RETROFITTED WITH POST-INSTALLED SHEAR REINFORCEMENT

Abstract

A post-installed shear reinforcement (PSR) method that is applied to flat plates such as foundation slabs and underground outer walls from inside the building was developed. In this study, the out-of-plane shear strength evaluation formula was proposed using the past test results. In addition, since these flat plates are subjected to seismic force while receiving earth pressure, it is expected that they will be in a complicated stress state during an earthquake. In such a case, finite element analysis is useful, so the experimental results were simulated to verify the finite element analysis method for the flat plate with PSR.
