EXPERIMENTAL STUDY ON STRENGTH AND DUCTILITY OF 3-DIMENSIONAL SHEAR WALL SUBJECTED TO HORIZONTAL TWO DIRECTIONAL LOADING

Abstract

The objective of this study is to investigate the elasto-plastic behavior of RC seismic shear wall subjected to horizontal two-directional loading. Static loading tests of box type and cylindrical shear wall were performed adopting various loading patterns on X-Y plane. According to the test results, the maximum shear force and skeleton curve of shear force - deformation angle relation are not so much affected by orthogonal damage and loading path. The concept of resultant shear force - total deformation angle was presented as one of the options to look into the property under horizontal two-directional loading.
