本文介绍了采用双层结构体系(结构墙和框架组合)建造的半比例两层预制混凝土结构的试验研究结果。在试验结构的一些梁柱节点中，一个典型的特征是节点区域的梁底纵筋锚固不良。试验结构受到模拟地震荷载的作用，直到结构达到破坏。本文着重介绍了预制结构构件及其节点在试验过程中的观测响应，包括梁柱连接、柱基础连接和横隔板。并对顶板与预制混凝土楼板之间的粘结性能进行了评价。探讨了预制混凝土建筑中节点和横隔板的抗震设计准则和规范含义，并对其设计提出了建议。
This paper describes the results of an experimental study of a half-scale two-story precast concrete structure built with a dual structural system (combination of structural walls and frames). A typical feature in some of the beam-to-column connections in the test structure was that the beam bottom longitudinal bars in the joint region were poorly anchored. The test structure was subjected to simulated seismic loading until the structure reached failure. This paper emphasizes the observed response of the precast structural elements and their connections during testing, including beam-to-column connections, column-to-foundation connections, and diaphragms. An evaluation of the bond between the topping slab and the precast concrete floor is also discussed. Seismic design criteria and code implications for connections and diaphragms in precast concrete buildings resulting from this research are explored, and recommendations for their design are offered.
