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

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．
