结构设计规范中关于预应力结构抗震设计若干规定的讨论

主要讨论了预应力混凝土结构抗震设计中，为了保证结构的延性要求，国家规范对预应力混凝土结构的受压区高度、纵向受力钢筋的配筋率以及预应力强度比等所做的若干规定，以及在满足规范规定的前提下，如何尽量发挥预应力混凝土结构优越性问题。

Discussion on Seismic Design of Prestressing Structures in the National Compulsory Code

In order to assure the requirement of the ductility of prestressing concrete structures, the national code strictly stipulates the height of compression zone, ratio of the longitudinal reinforcement, and the ratio of prestressing strength etc. in prestressing concrete structures. In this paper, some of the stipulations in the national compulsory code on seismic design of prestressing concrete structures are introduced and it is mainly discussed how to give more superiority of the prestressing concrete structure under the condition satisfying the stipulations of the code.
