摘要(Abstract):
报道了9根不同剪力连接度钢-混凝土组合梁(5根简支组合梁,4根连续梁)的低周竖向反复荷载部分试验研究结果。对钢-混凝土组合梁的破坏形态、滞回规律、耗能能力、刚度退化规律等抗震性能进行了深入的分析,重点探讨了不同剪力连接度对钢-混凝土组合梁抗震性能的影响。
The test results of seismic resistant performance of steel-concrete composite beams under cyclic points concentrated loads are introduced including five single-span steel-concrete composite beams and four two-span steel-concrete composite continuous beams(5 SCB and 4 CCB).It deeply analyzes the difference of the failure mode,load and deformation curve,ductility,the degradation of strength and rigidity,deformation-rehabilitation capacity etc.The effect of shear connection degree is researched on the seismic resistant performance of steel-concrete composite beams.
