Abstract: The mechanical behavior for one-way single-layer cable curtain walls was analyzed. A formula on calculating 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.
Keywords: One-way single-layer cable curtain wall; cable cross-section; initial strain; temperature load; boundary stiffness
