摘　　要：利用ANSYS程序建立了悬挑型脚手架的型钢(工字钢、槽钢)梁与钢丝绳共同作用的三维有限元模型。假设钢丝绳在初始状态张紧条件下,对不同型号的悬挑梁和钢丝绳进行模拟分析,对悬挑梁与钢丝绳共同承受脚手架荷载进行探讨,以确定工字钢、槽钢梁与钢丝绳所各自分担的荷载比例,并对两种悬挑公式计算结果进行对比分析,提出了钢丝绳参与结构受力计算并提供可靠支撑的必要条件。3 D finite element mo the steel beam and eable-staye tensioning eonditi and dete and analyzed, an ons, different d discussions del is created using ANSYS for cantilever scaffold with combined action of d steel wire rope. Assuming that the steel wire rope was in the initial combinations of the cantilever beam size and the wire rope were simulated were performed regarding the load bearing mechanism of the scaffold to rmine the respective share of scaffold loads taken by the I-shape steel beam, the channel steel the steel compared, and wire rope. The calculation results from two formulas for the cantilever beams results were proposed on the necessary conditions for the steel wire rope to be includ stress calculation and provide reliable support. beam were ed in
