钢管混凝土抗震性能研究现状综述

he paper briefly expounds the present situation of the research on the aseismatic performance of concrete filled steel tubes which includes the performome of members，joint and frames.and which includs experimental research measure，experimental research ，alculating method and calculating theory at home and abroad，then it analyses the shortcoming which exist in the research.this paper explain several mostly problems in the search of aseismatic behaviors of concrete filled steel tubes. Finally，the fature development of the aseismatic performance research on concrete filled steel tubular structures is forecasted.
