【摘要】 采用弯矩－曲率法，对部分预应力砼受弯构件，在张拉、加载和卸载阶段分别进行受力特性的非线性分析，并讨论了影响构件载面延性指标的主要因素．文中提出部分预应力砼受弯构件曲率延性系数的计算方法．更多还原

【Abstract】 By flexure moment-curvature method,a nonlinear analysis is made on force-receiving characteristic of partially prestressed concrete flexural members during the stages of jacking,loading and unloading. The authors discuss the principal factors influencing ductility index of the section of member;and put forward a method for calculating ductility coefficient of the curvature of partially prestressed concrete flexural members.更多还原
