摘要
海南省体育中心综合训练馆为单跨36m预应力框架及屋盖网架的三层混合结构。为解决单跨结构抗震问题,在建筑两端设置抗震墙作为主要抗侧力结构;为解决大跨边柱的大偏心受压问题,在边框架柱中设置斜向预应力筋,并通过设置牛腿增大预应力筋偏心距及解决柱张拉端问题。该文对强震区的大跨预应力梁柱设计,尤其是预应力柱的计算分析方法具有较大的参考意义。
The general physical training gymnasium of Hainan Sports Centre is a three storey composite structure consisting of a 36m span prestressed concrete frame and a lattice roof structure.The aseismic walls were set at two ends of the building as the principal structural component to resist lateral force for single-span structure.Prestressed reinforcements were set in side frame columns to overcome the large eccentric compression problem.Corbels were set to solve the tension anchorage problem,and to increase the eccentricity of prestressed reinforcements.The research in this paper can provide some reference for the design of large-span prestressed concrete beams and columns (especially the analytical method of prestressed concrete columns) in meizoseismal area.
