Abstract:

联肢剪力墙结构抗震性能控制是目前尚未很好解决的问题之一。该文以连续化方法的解析解为基础,在联肢剪力墙高度、截面尺寸和材料性能等已知的条件下,首先通过控制联肢剪力墙满足整体位移延性需求的耦联率来确定连梁的截面尺寸;然后通过控制联肢剪力墙结构顶点和层间侧移角来确定其基底剪力,并假定水平地震作用沿高度为倒三角形分布;最后确定连梁满足位移延性需求的弦转角需求,并依据连梁两端相对竖向变形需求确定连梁所需要的约束箍筋数量,连梁箍筋数量同时应满足受剪承载力要求。分析结果表明,根据联肢剪力墙的整体位移延性需求、目标耦联率以及连梁两端相对竖向变形需求所确定的连梁约束箍筋数量比较合理;当耦联率在0.4~0.66取值时,连梁的箍筋数量由受剪承载力计算控制。
