|
摘要
通过对剪跨比为2.5的10根SRC-RC转换柱和1根钢筋混凝土柱的低周反复载荷试验,研究SRC-RC转换柱在压、弯、剪共同作用下的抗震性能。以型钢延伸长度、轴压比、配钢率为试验参数,分析了试件的主要破坏形态、滞回曲线、耗能性能和延性,并详细探讨了各参数对SRC-RC转换柱抗震性能的影响。
The seismic performance of SRC-RC transition column under joint action of pressure,bending force and shear force is researched according to low-cycle loading test of 10 pieces of SRC-RC transition columns whose shear span ratio is 2.5 and one piece of reinforced concrete column.Main destruction types,hysteretic curve,energy consumption performance and ductility are analyzed according to some test parameters,such as extension length of profile steel,axial compression ratio and reinforcement rate,etc.The influences of various parameters on the seismic performance of SRC-RC transition column are discussed in details.
