In-Plane Seismic Resistance of Two-Story Concrete Masonry Walls with Openings

这个项目是最近一个项目的延续，该项目是在协调的TCCMAR项目下研究带开口的两层砖石墙的面内抗震性能。将使用现有的测试装置进行额外的实验工作，以允许(1)地板水平的面外运动，以及(2)面外载荷的应用。这项额外的研究将解决两种不同设计概念之间存在的差异：(a)地震破坏集中在垂直砌体墩上；(b)墙壁应设计成耦合墙，在这种情况下，破坏将集中在墙壁基座上。本研究将拓宽砌体墙设计概念的理论基础，促进合理设计方法的发展，以抵御地震荷载。

This project is a continuation of a recent project to study the in-plane seismic resistance of two-story masonry walls with openings under the coordinated TCCMAR program. Additional experimental work will be conducted, using the existing test set-up to permit (1) out-of-plane movement at floor levels, and (2) application of out-of-plane loads. This additional study will resolve the discrepancies existing between two different design concepts: (a) the earthquake damage is concentrated in vertical masonry piers and (b) the walls should be designed as coupled walls in which case the damage will be concentrated at the wall bases. This study will broaden the theoretical basis of masonry walls design concepts and facilitate the development of rational design methodologies to resist seismic loads.
