[提要] 《钢结构设计规范》(GBJ-88)中没有预应力钢(混凝土组合结构方面的内容,针对福建会堂工程的设计实例,探讨了35m单跨简支预应力钢-混凝土组合箱梁的结构设计方法。实际工程表明,预应力钢-混凝土组合结构比钢-混凝土组合梁更具有优越性。[关键词] 预应力; 钢-混凝土组合结构; 设计方法; 箱梁Abstract: The design method of prestressed steel-concrete composite box beam is not discussed in Code dot Design of Steel Structure(GBJ17-88).The design method was studied about the prestressed steel-concrete composite beam with 35m span in Fujian Hall project.The practical project indicates that the prestressed steel-concrete composite structure is more superior than steel—concrete composite.Keywords:prestressed steel-concrete composite structure; design method; box beam
