How to ensure this new structure to be in elastic state under frequent earthqu ake, be mendable under design earthquake and not collapse under infrequent earthquake, especially the last item, is the problem to be solved imminently in engineering field. Center around this problem, 5 aspects of investigation are carried out as following:(1) The experiment of seismic performance of ASCCs in this new frame structure has not been reported, in order to study this problem, 9 ASCC specimens with shear steel plate are tested subjected to the horizontal low cyclic loading, in which, the shear span ratio is 3 and axial compression ratio is different. The hysteretic curves of 9 specimens are obtained. The seismic performance indexes such as energy dissipation, stiffness degradation, strength degradation, skeleton curves and ductility of this kind of column are acquired, and the seismic fortification measures including ultimate values of axial compression ratio under different seismic degree are suggested.
