Masonry construction comprises a large portion of building construction in the U.S. and the world. Reinforced masonry construction use is increasing in moderate to higher seismic zones because of its apparent features of economy, fire safety, architectural flexibility, and ease of construction. The present state of masonry structural analysis and design and materials and construction technologies does not enable an accurate prediction of building behavior under lateral loads such as seismic loads. This research project is an experimental and analytical investigation of the seismic response of concrete plank diaphragms. Many masonry buildings are constructed with floor slab systems consisting of concrete planks. The first of two tasks will be full-scale experimental tests of concrete diaphragm slabs. The second task will integrate existing diaphragm data with the experimental test data to determine the behavioral and strength characteristics.

在美国和世界范围内，砖石建筑占建筑建筑的很大一部分。由于配筋砌体结构具有明显的经济性、防火安全性、建筑灵活性和施工简便性等特点，在中高地震区的使用日益增多。目前的砌体结构分析和设计以及材料和施工技术无法准确预测建筑物在横向荷载(如地震荷载)下的行为。本研究项目是对混凝土楼板横隔板的地震反应进行试验和分析研究。许多砖石建筑是用混凝土板组成的楼板系统建造的。两项任务中的第一项将是混凝土地下连续板的全尺寸实验测试。第二项任务是将现有的隔膜数据与实验测试数据相结合，以确定其行为和强度特性。
