The effects of the shaped steel, stirrups and concrete on shear capability in the shear-bond failure are discussed. Based on experimental data, an empirical formulation of the shear-bond capability of solid-webbed steel reinforced concrete short column is proposed and the results show good agreement with the test results.Keywords:steel reinforced concrete composite short column; shear-bond failure; shear-bond capability作者簡介:魏建萍,碩士,講師,Email:wjp750811@sina.com。參考文獻[1]JGJ138—2001型鋼混凝土組合結構技術規(guī)程[S].北京:中國建筑工業(yè)出版社,2002.[2]中國建筑科學研究院.混凝土結構研究報告選集3[M].北京:中國建筑工業(yè)出版社,1994.[3]日本建筑學會.鐵骨鐵筋コンクリ一卜構造計算規(guī)·同解說[M].日本建筑學會,2001.[4]魏建萍.型鋼混凝土短柱剪切粘結承載力試驗研究[D].西安:西安建筑科技大學,2006.[5]牟星之,姜維山,趙鴻鐵.型鋼混凝土短柱抗震性能的試驗研究[J].西安冶金建筑學院學報, 1991,23(3):266-276.[6]王海龍,江見鯨. 勁性鋼筋混凝土框架柱抗震行為的試驗研究及分析[C]//混凝土結構基本理論及工程應用全國第五屆學術會議論文集.天津:天津大學出版社,1998:5-9.
