This project focuses on the development of an earthquake resistant design technique for structures made out of precast prestressed concrete members. The emphasis is on developing a strong and ductile cast-in- place joint between the precast column and beam elements. The main parts of this project are: (1) the study of ductility of partially prestressed concrete members subjected to simulated seismic type excitations, (2) the evaluation of ductility demand of the structure to the joint, (3) the study of the joint-connection using typical beam-column elements, and (4) the study of model frames with selected connection using pseudo-dynamic testing. The project, if successfully completed, would have a major impact on the prestress concrete industry.

该项目的重点是开发一种抗震 预制预应力混凝土结构设计技术 成员 重点是开发一种强度高、韧性好的镶铸钢， 在预制柱和梁构件之间放置接头。 本课题的主要内容是：（1）对预应力混凝土梁的延性进行了研究， 模拟地震作用下部分预应力混凝土构件 型激励，（2）结构延性需求评估 （3）节点连接的研究 典型梁柱单元的研究;（4） 使用伪动态测试选择连接。 如果项目 成功完成，将对预应力产生重大影响 混凝土工业。
