基于纤维模型的预应力混凝土桥墩滞回性能分析
Study on Hysteretic Behavior of Prestressed Concrete Bridge Pier with Fiber Model
摘要
Abstract
Abstract:The effects of the prestressed tendon reinforcement ratio,the ordinary longitudinal reinforcement ratio and the stirrup reinforcement ratio on the hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier have been obtained with the fiber model analysis method.The analysis results show that for the prestressed concrete bridge pier:the greater the prestressed tendons reinforcement ratio and the ordinary longitudinal reinforcement are,the more obvious the pier's hysteresis loop "pinching effect" is,the smaller the residual displacement is,the lower the energy dissipation capacity is; and the greater the stirrup reinforcement ratio is,the larger the hysteresis loop area is,the better the ductility of bridge piers is,the greater the shear capacity is.The research results will provide a theoretical basis for the hysteretic behavior analysis of the prestressed concrete pier.关键词
