STM(Strut and Tie Mode1)模型具有力学概念明晰、受力直观、简便和易于掌握等优点,已经被广泛用于结构复杂区域或构件配筋计算和梁柱节点强度校核等。基于STM模型的概念,本文提出一种由拉杆、压杆和刚性梁组成的剪力墙宏观单元模型,用于离散高层钢筋混凝土结构中的剪力墙,尝试改进高层钢筋混凝土结构弹塑性地震反应分析中的剪力墙模拟问题。
Hybrid Coupled Walls (HCW) are comprised of two or more reinforced concrete wall piers
connected with steel coupling beams distributed over the height of the structure. Extensive
research over the past several decades suggests that such systems are particularly well suited for use in regions of moderate to high seismic risk. This paper reviews the state-of-the-art in seismic modeling, analysis and design of hybrid coupled wall systems. Design methodologies are
presented in both prescriptive and performance-based design formats and a discussion of alterative types of hybrid wall systems is provided.
框架. 剪力墙结构和框架. 核心筒结构 中, 钢筋混凝土楼面梁和剪力墙或核心筒的连接经常会 出现两种节点情况: 平面内节点: 即梁与墙在同一平面内连接; 平面外节点, 即梁以一定角度与墙连接。文中研究的重点为后者, 且为垂直连接的节 点形式, 目前国内外对此类节点的研究还比较少。采用 A N S Y S分析软件对配暗柱剪力墙构件进行了非线性有限元分析, 并进 行了实验验证。
