介绍了具有单个横撑的预应力斜柱的一般设计方法。通过与物理试验的结果进行比较,验证了所提出的设计表达式和其有限元模拟的准确性。根据欧洲规范EN1990中的附录D对该方法的可靠性进行评估。给出的预应力斜柱的抗力表达式为系统几何参数、悬索的初始预应力水平和整体缺陷水平的函数。对提出的设计方法通过实例进行了介绍。
The general design method of prestressed inclined column with single cross brace is introduced. The accuracy of the proposed design expression and its finite element simulation is verified by comparison with the results of physical experiments. The method is evaluated for its reliability in accordance with Appendix D of the European norm EN1990. The resistance expressions of the prestressed inclined columns are given as a function of the system geometry parameters, the initial prestressing force of the suspension cables and the overall level of defects. The proposed design method is introduced by examples.
