摘　　要：单层索网幕墙中拉索的结构设计非常重要,以往工程通常采用反复试算来确定拉索的直径和初始预拉力。本文针对这种情况提出一套简捷的计算方法,不但能根据已知挠度限值快速算出拉索的最大内力,确定拉索的直径大小,而且还能反推出拉索的初始预拉力,帮助工程师进行拉索的分析校核和指导现场张拉施工。The structure design of the tension cable in monolayer cable net curtain wall is very important. Generally the diameter and initial pre-tension of the tension cable is identified via iterative computing in the past works. This paper proposes a simple computing method for this case, which not only quickly computes the maximal internal force of the tension cable by the known deflection limit and identify the diameter of the tension cable, but also deduces the initial pre-tension of the tension cable and assist engineers to analyze and calibrate the tension cable and guide field tension construction.
