It is necessary to evaluate appropriately the seismic-resistivity performance, especially ductility, of Steel Reinforced Concrete (SRC) members for designing SRC structures more reasonably and more economically. In this study, the calculation method of yield point displacement and ultimate point displacement (ductility factor) of SRC members is investigated analytically and statistically. In the deformation of SRC member, the deformation of column-body and the rotational displacement due to pulling-out of steel from footing concrete are considered. In this manner, it is possible to evaluated the ductility of SRC members accurately.
