摘　　要：介绍了西安音乐学院演艺中心工程25.7m跨后张法有粘结预应力框架梁的设计方法,在8度抗震设防大跨结构中应采用预应力筋与非预应力筋的混合配筋方式,能较好地满足建筑空间和使用功能要求。但是由于我国现行规范中没有预应力混凝土结构的抗震设计专门条款及构造措施,而仅仅对预应力混凝土的抗震设计提出了一般的要求,在抗震区使用部分预应力混凝土结构保证构件截面延性很重要,同时应注意控制预应力度和截面的相对受压区高度。This paper introduces the method for design of 25.7m span post-tensioned bond prestressed frame beam in performing art center of Xi＇ an Music college. Using mixed type of prestressed and nomprestressed reinforcements in Intensity 8 seismic fortificated large-span structure can satifsfy firely the demand for architectural space and use function. In current code, there are not special clauses and construction measures on prestressed concrete structure design and only there are some general demand for seismic design for prestressed concrete structure. It is important to use partial prestressed concrete structure in seismic zone to ensure ductility of component section. At the sametime, we should play attention to control the degree of prestress and the height of relative compressed zone of cross section.
