摘要
结合32m跨部分预应力混凝土梁的设计,对梁的材料选择,预应力筋布置,内力计算,预应力筋选配,预应力损失及构造措施等问题进行分析。同时计算了由张拉控制力对梁产生轴向变形而引起的内力,强调该内力在设计中不可忽视。
Selection of beam material, layout of prestressed tendon, calculation of internal force, selection of prestressed tendon, prestress loss and construction measure are analyzed with consideration of design of partial prestressed concrete beam with 32m span. Meanwhile, internal force that is generated by axial deformation of beam under stretching force is calculated, so as to emphasize that the internal force shall not be ignored in design.
