摘要
通过对2个小跨高比新型配筋方案带板连梁与不带板连梁试件在低周反复荷载作用下的对比试验,揭示了整浇楼板对抗震连梁裂缝发育及破坏形态的影响规律,同时分析了带板连梁的强度发展、刚度退化、滞回及耗能性能等抗震特性,根据受力机理探讨了连梁的变形性能,提出了楼板在参与连梁抗剪作用中的有效板宽范围。
Based on comparative experiment research of 2 small span to depth ratio new reinforcement scheme coupling beams with slab and without slab under low frequency cyclic load, the effect of casting slab on fissure＇ s development and failure mechanism of seismic coupling beams is put forward. The paper also analyze the seismic performance of strength development , stiffness degeneration, hysteretic and energy dissipation behavior of coupling beam with slab. The deformation behavior of coupling beam is discussed based on force mechanism and the effective width of slab is brought forward to calculate the shear capacity of the coupling beams.
