摘要
分析了单层单向索网幕墙的受力性能,并给出了最优索截面和初应变的计算公式。考虑了温度荷载和边界刚度对索截面和初应变的影响,得出了不锈钢索和高钒索的索截面快速估算公式,给出了常规索网的初应变合理取值范围,大大减少了有限元软件计算中的试算工作量。
The mechanical behavior for one-way single-layer cable curtain walls was analyzed. A formula on calcu]ating optimum cable cross-section and initial strain was presented. Considering the effect of the temperature load and boundary stiffness on cable cross-section and initial strain, quick estimation formula on cable cross-section of stainless steel cable and high-vanadium was obtained. At the same time, the proper value range of initial strain for conventional cable nets was given out, reducing the workload for the finite element analysis of trial calculation.
