应用虚功原理和变形协调条件,本文得到了考虑多种因素的求解水平带状桁架最佳位置和侧移折减系数的计算式。而后对影响水平带状桁架最佳位置以及侧移折减系数的因素,如核心筒刚度与外柱刚度之比α、核心筒线刚度与伸臂线刚度之比β和结构特性沿高度变化等逐一进行了分析。在此基础上,给出了一组实用计算图表,以供设计人员参考。
Applying the principle of virtual work and the conditions of deformation coordination, this paper obtains a formula for calculating the optimal position and lateral displacement reduction factor of the horizontal truss truss considering various factors. The factors affecting the optimal position of the horizontal truss truss and the sideshift reduction factor, such as the ratio α of the stiffness of the core cylinder to the stiffness of the external pillar, the ratio β of the stiffness of the core cylinder to the stiffness of the extension line, and the change in the structural characteristics along the height, etc. One by one analysis. Based on this, a set of practical calculation charts are given for designers’ reference.
