(Institute of Architecture and Civil Engineering of Taiyuan University of Technology, Taiyuan 030024, China)Abstract: The frame-supported shear wall structure using SRC columns and that using RC columns under verticalload and both vertical & horizon load were analyzed by ANSYS, a universal firute element analysis software. The influences of the steel contents and the ratio of stirrup to the performance of SRC columns were analyzed. The main conclusions as following: Using SRC columns can reduce the vertical displacement of the whole structure especially the frame-supporting beam under verticalload and the middle bottom of the beam makes the most obvious performance; Using SRC columns can reduce the depth of neutral axis in frame-supporting beam and improve its crack resistance; Under both the vertical and horizon load, the maximum horizontal stress appears in the intersecting part between the frame-supporting beam and shear wall, the maximum vertical stress appears at the bottom of the column that away from the horizontal force, the maximum shear stess appears in the inside of beam-column joints; The maximum horizontal stress of the SRC column appears about in the position of under the tops of the column l/3 height of it; The maximum vertical stress appears at the bottom of the column that away from the horizontal force; Using SRC columns can make the force displacement curve of the structure appear a considerable platform. It shows that the structure using SRC column has a better ductility than that using RC column; The ductility of SRC columns will increase significantly with the enlargement of steel contains and the ratio of stirrup within a certain range. Whereas, the steel contains in the element are not the more the better.
