| 摘 要： | 简要介绍了重庆浪高凯悦大酒店工程有粘结预应力扁梁的设计特点。在设计中应用有限元程序，分析了梁柱刚度对梁轴向预压力的影响。通过对柱及墙体预留后浇带减小了竖向构件对预应力梁的约束作用，降低了梁中的次轴力，使设计经济合理。对同类工程设计具有一定的参考价值。

| Abstract: | This article briefly introduces the design characteristics of bonded prestressed flat beams for the Chongqing Langgao Hyatt Hotel project. In the design, the finite element program is used to analyze the influence of beam column stiffness on the axial preload of the beam. By reserving post pouring strips for columns and walls, the constraint effect of vertical components on prestressed beams is reduced, and the secondary axial force in the beams is reduced, making the design economical and reasonable. It has certain reference value for similar engineering designs |
