摘要:
总结了各国学者对方、矩形钢管混凝土剪切性能的研究现状，阐述了当前研究的特点与不足，指出了需要进一步研究的问题。鉴于剪跨比、轴压比、钢管对混凝土的约束效应等因素对剪切性能的影响较大，各种破坏形态的界限尚缺乏统一的判定标准，根据相关试验数据，对比了各种承载力公式的计算结果，分析了产生差别的原因。基于工程实际的需求，对未来研究工作提出了进一步的建议。
Abstract:
Authors intended to summarize the research status on shearing performance of square and rectangular concrete-filled tubes(CFT) conducted by domestic and foreign scholars. Characteristics and shortcomings of current studies were demonstrated, further studies also were pointed out. Shearing performances were affected by many factors, such as shear-span ratio, axial load ratio and constraint effect of steel tubes, etc. Unified criteria on the boundaries of each failure pattern was not accepted by all the researchers. According to some test data, calculated results of various bearing capacity formulae were compared, and the reasons of difference were discussed. On the basis of practice requirements, several proposals on the future work were listed in the present research.
