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作者简介:魏建萍,硕士,讲师,Email:wjp750811@sina.com。参考文献[1]JGJ138—2001型钢混凝土组合结构技术规程[S].北京:中国建筑工业出版社,2002.[2]中国建筑科学研究院.混凝土结构研究报告选集3[M].北京:中国建筑工业出版社,1994.[3]日本建筑学会.铁骨铁筋コンクリ一卜构造计算规·同解说[M].日本建筑学会,2001.[4]魏建萍.型钢混凝土短柱剪切粘结承载力试验研究[D].西安:西安建筑科技大学,2006.[5]牟星之,姜维山,赵鸿铁.型钢混凝土短柱抗震性能的试验研究[J].西安冶金建筑学院学报, 1991,23(3):266-276.[6]王海龙,江见鲸. 劲性钢筋混凝土框架柱抗震行为的试验研究及分析[C]//混凝土结构基本理论及工程应用全国第五届学术会议论文集.天津:天津大学出版社,1998:5-9.
