Tubed RC columns connected conveniently with RC beams in respect that the outer steel tube does not pass through the beam to column connection. Tubed RC columns also exhibits excellent strength and seismic behavior, therefore it is a new kind of composite structure that can be widely used in civil engineering. Tubed RC columns are used in Dalian Gymnasium to improve the anti-seismic performance of the ultra short columns.Tubed RC columns used less steel and they are conveniently constructed in this structure, exhibiting well economical and compositive effect.Keywords:tubed reinforced concrete; beam-column connection; short column; strength; anti-seismic performance*國家自然科學基金(50708027)，黑龍江省自然科學基金(E2007-24)。作者簡介：張小冬，碩士，教授，一級注冊結構工程師，Email: 163zhangxiaodong@163com。參考文獻［1］YB9082—2006 鋼骨混凝土結構技術規(guī)程 ［S］. 北京：冶金工業(yè)出版社，2003.［2］鐘善桐，白國良. 高層建筑組合結構框架梁柱節(jié)點分析與設計［M］. 北京：人民交通出版社，2006.［3］CECS159:2004 矩形鋼管混凝土結構技術規(guī)程 ［S］. 北京：中國計劃出版社，2004.［4］XUHONG ZHOU, JIEPENG LIU.
