世构体系框架中节点抗震性能试验研究
|
摘要
通过对3个不同键槽长度的世构体系(预制预应力混凝土装配整体式框架结构)梁柱节点的低周反复荷载试验,研究世构体系框架节点的破坏形态、滞回性能、节点延性、耗能能力和刚度强度退化等抗震性能指标,对世构体系的抗震性能得出一个大致的评价。试验结果表明:世构体系的滞回曲线丰满,具有良好的耗能能力;世构体系的配筋设计可以参照现行的混凝土结构设计规范进行;经过良好的设计施工,世构体系的抗震性能完全能够满足预期的要求;目前采用的键槽长度能够满足抗震的需要。
The seismic behavior of joints of SCOPE system(Frame structures comprised of precast prestressed concrete components) was investigated under low cyclic and reciprocal loading.The specimens had three joint members with different lengths of service hole.The estimation was given on the seismic performance of SCOPE system joint on the basis of the failure mechanism on the beam-column connections,as well as hysteretic loops,ductility,energy dissipation,strength and stiffness degeneration etc.The test result shows that the SCOPE system joint has full hysteretic loops and better energy dissipation capacity,and the design of SCOPE system joint can be done according to the existing design of concrete structure code.The seismic performance of joints of SCOPE system can satisfy the demand if they are well designed.The service hole length of the members can satisfy the seismic demand.
