Abstract

A type of precast concrete structure system with precast reinforced column, precast prestressedconcrete beam and slab was investigated. The structural details such as beam-to-column connection, column-foundation and precast slabs were firstly presented. Then the seismic performance of the system was discussed by the cyclic loading test on interior beam-to-column joints and pushover analysis of a numerical example with structural analysis software OpenSees. The analytical and experimental results shows that this precast system has following outstanding characters such as the adoption of first prestressed easily, the reduction in the height of member section, convenient construction of joints and low amount of steel usage. The hysteretic loop of beam-to-column joint is full and energy dissipation capacity of the joint is excellent. And the mode of system behavior in the post-elastic range during seismic loading is the perfect beam sidesway mechanism. It is thus concluded that this system has an excellent seismic behavior.

预制混凝土结构体系的研究

研究了一种由预制钢筋柱、预制预应力混凝土梁、板组成的预制混凝土结构体系。首先介绍了梁柱连接、柱基础和预制板等结构细节。然后，利用结构分析软件OpenSees对该体系进行了内部梁柱节点的循环加载试验和数值算例的推覆分析，探讨了该体系的抗震性能。分析和试验结果表明，该预制体系具有易于采用首次预应力、降低构件截面高度、节点施工方便、钢材用量少等突出特点。梁柱节点滞回环饱满，节点的消能能力优良。在地震荷载作用下，后弹性范围内的体系行为模式为完善的梁侧移机制。因此，该体系具有良好的抗震性能。
