Evaluation of Ductile Connections for Precast Frame Systems

该项目是明尼苏达大学、德克萨斯大学奥斯汀分校、和华盛顿大学在PRESS第二阶段协调研究计划下对预制混凝土延性节点框架中的梁柱连接进行了试验和分析研究。试验研究分为三个阶段：(1)连接构件，(2)梁柱组合，(3)多跨组合。测试的第一阶段调查一系列组件或连接元件，这些组件或连接元件是Presss第一阶段计划目前正在考虑的许多连接中的常见组件或连接元件。梁柱连接组件试验将被用来调查至少三种类型的梁柱框架连接，将由Presss第一阶段的研究人员详细说明。测试结果将用于开发代表连接行为的分析模型。该项目的最终结果将是制定预制混凝土延性梁-柱-楼板连接的设计建议，并详细说明在接缝区域交界处和通过接缝区域的剪力传递准则。

This project is a collaborative research effort between the University of Minnesota, the University of Texas at Austin, and the University of Washington for an experimental and analytical investigation of beam-column connections in precast concrete ductile-joint frames under the PRESSS Phase II Coordinated Research Program. The experimental research is divided into three phases of tests: (1) connection components, (2) beam-column subassemblages, and (3) multibay subassemblages. The first phase of testing investigates a series of components or connecting elements that are common among many of the connections currently under consideration by the PRESSS Phase I Program. Beam-column connection subassemblage tests will be used to investigate at least three types of beam-column frame connections to be detailed by PRESSS Phase I researchers. Results of the tests will be used to develop analytical models to represent connection behavior. The end result of this project will be the development of recommendations for the design of precast concrete ductile beam- column-floor panel connections and detailing guidelines for shear transfer at the interface of and through joint regions.
