中文摘要：
通过16个试件的低周反复荷载试验，对SRC-RC竖向混合结构转换柱的受力性能进行了研究。转换柱的破坏形式可分为剪切破坏、弯曲破坏和粘结破坏。对转换柱特殊的破坏过程和破坏形态进行了描述和分析，并结合箍筋应变在整个加载过程中的发展变化状况，揭示了其破坏机理。根据转换柱特有的构造形式提出了等效剪跨比的概念，用于反映型钢局部存在对转换柱抗剪承载力的影响，给出了计算剪跨比与等效剪跨比的换算公式。给出了便于工程应用的抗剪承载力计算公式，计算结果与试验结果符合较好。
英文摘要：
The study on the behavior of transfer columns in a SRC-RC hybrid structure has been carded out, based on the experiment of 16 specimens under low cyclic reversed loading. Failure can be divided into shear failure, bend failure and bond failure. Failure patterns are described and analyzed. The failure mechanism of transfer columns is revealed by taking the development of stirrup strain into consideration. The equivalent shear span ratio of transfer columns is proposed based on the special configuration and arrangement of shape steel, which displays the effect of partially existence shape steel on shear capacity. The conversion formula for calculated shear span ratio and equivalent shear span ratio has been proposed. The formula for shear capacity calculation is derived and the calculated results are consistent with those of the test.
