Innovative Concept for Precast Prestressed Concrete Seismic Resistant Frames

本项目致力于发展预制预应力混凝土构件结构的抗震设计技术。重点是在预制柱和梁构件之间开发坚固和延性好的现浇接头。本项目的主要内容包括：(1)模拟地震型激励下部分预应力混凝土构件的延性研究；(2)结构对节点延性需求的评估；(3)采用典型梁柱单元进行节点连接研究；(4)拟动力试验研究选定节点的模型框架。该项目如果成功完工，将对预应力混凝土行业产生重大影响。

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.
