STATE-OF-THE-ART RESEARCH ON MECHANICAL PERFORMANCE OF STEEL REINFORCED CONCRETE IRREGULAR SECTION COLUMN STRUCTURES

型钢混凝土异形柱结构不仅具有异形柱结构的房间柱棱不凸出、美观适用、实际得房率高等优点,同时能够克服钢筋混凝土异形柱结构承载能力不足、抗震性能差等缺点,对于进一步推广异形柱结构具有重要意义。在综合介绍型钢混凝土异形柱结构研究背景的基础上,分析了型钢混凝土异形柱轴心受压性能、偏心受压性能、受剪性能和抗震性能、型钢混凝土异形柱框架节点的受剪性能和抗震性能、型钢混凝土异形柱框架的抗震性能以及构造要求等方面的研究现状,指出了型钢混凝土异形柱结构受力性能研究领域有待进一步解决的问题,为该领域的深入研究及型钢混凝土异形柱结构的设计应用提供参考。

Steel reinforced concrete （SRC） irregular section columns structure can not only make better use of available space and improve the esthetic appearance of structure, but also overcome the weakness of reinforced concrete structure, such as bearing capacity is insufficient and seismic performance is poor. Therefore it has important significance to promote the use of irregular section column structure. Based on the introduction of research background of SRC irregular section column structure, this paper summarizes the research status in the following field as axial compression performance, eccentric compression performance, shear performance and seismic performance of SRC irregular section column, shear performance and seismic performance of joint in the SRC frame with irregular section columns, seismic performance of SRC frame with irregular section columns and construction requirement. Also, the problems which have not been solved are pointed out. This work can provide references for the intensive research and application of SRC irregular section column structure.
