摘要:
为了缓解联肢剪力墙中小跨高比连梁发生低延性的剪切破坏,增强连梁的变形和耗能能力,可在单连梁中轴线位置设置半通缝并配置交叉斜筋,形成半通缝连梁。本文完成了的对7种连梁的模拟,分析了在小跨高比、低周反复荷载作用条件下不同类型带楼板连梁的承载力、变形能力、刚度退化和耗能能力以及不同跨高比、不同开缝位置对带楼板半通缝连梁抗震性能的影响。结果表明:楼板会使半通缝连梁的剪压比增大,延性下降;但相比于普通连梁和双连梁,半通缝连梁具有较好的变形能力和承载力,可在实际中推广。
Abstract:
Semi seam coupling beam can be formed with half through slot in the axis of the common coupling beam and diagonal reinforcement, to alleviate the low ductility shear failure of small span-depth ratio coupling beam, and strengthen deformation capacity and energy dissipation capacity of coupling beam. Under the condition of small span-depth ratio and low cyclic loading, the simulation analysis of 7 types of coupling beams is carried out, to analyze the bearing capacity, deformation capacity, stiffness degradation, energy dissipation capacity of different types of coupling beams, and the effect on seismic performance made by different span-depth ratio and slot position of semi seam coupling beams with slab. The results show that slab increases the shear compression ratio of the coupling beam, and makes ductility worse; however, compared with common coupling beam and slotted coupling beam, the semi seam coupling beam has better deformation capacity and bearing capacity,which is worth popularizing in practical engineering.
