SRC-RC竖向混合结构转换柱研究现状综述
|
摘要
通过16根转换柱试件及钢筋混凝土柱对比试件的低周反复荷载试验,分析型钢延伸高度、箍筋配置和型钢配钢率对转换柱受力性能的影响,为SRC-RC竖向混合结构的推广应用提供科研基础与参考.指出:(a)由于型钢的局部存在,转换柱容易产生类似于RC短柱的剪切破坏,破坏主要集中在RC部分,钢与混凝土之间的共同工作会导致此类破坏发生;(b)为了保证转换柱具有更好的抗震性能,应采取构造措施控制剪切裂缝的发展,避免剪切破坏,提高构件的变形能力.建议构件全高箍筋加密或在RC部分设置X形交叉钢筋.在对转换柱特殊破坏方式充分认知的基础上,对新的构造措施与配钢方式进行了展望.
Through experiments on 16 transfer columns under low cyclic reversed loading,the effects of factors including the extended height,the stirrup ratio,and the shaped steel ratio on the bearing capacity of the transfer columns were analyzed.This analysis provides a basis and references for extensive applications of SRC-RC vertical hybrid structures.The results show the following:(a) Due to the partial existence of the shaped steel,the transfer columns,like the RC short columns,are easily subjected to shear failure.This failure mainly occurs in the RC part and is caused by the interaction between concrete and the shaped steel.(b) To ensure a good anti-seismic performance of the transfer columns,construction measures that can restrict the development of shear cracks,avoid the shear damage,and improve the deformation ability of specimens should be taken.It is suggested that X bars and more stirrups be used for the specimens.Based on a comprehensive understanding of the special failure modes of the transfer columns,new methods for steel arrangement and configuration are put forward.
