【摘要】 介绍了哈尔滨体育学院冰球馆工程概况,提出了同一轴线上不等跨、不等高且相邻跨预应力筋用量不同时的双跨预应力混凝土框架梁的预应力筋布置方案及张拉方法,给出了基于裂缝控制方程的预应力筋用量计算、基于抗力和构造要求的非预应力筋用量的计算确定、变形验算等相关计算过程,可供同类工程设计建造时参考。更多还原

【Abstract】 The general introduction of ice hockey gymnasium in Harbin institute of physical education is introduced.Arrangement and tension methods for prestressing reinforcements in two-span prestressed concrete beam are presented in which length of span,depth of beam and number of prestressing reinforcement in the same axis are different.Some calculation processes are given such as placing of prestressing reinforcements on the basis of equations of crack control,placing of nonprestressed reinforcements on the basis of resistance and construction requirements,deformation check and so on.All these can provide references in design and construction of the similar project.更多还原
