摘要
本文利用分层空间桁架法对风荷载作用下的通信三管塔进行理论计算,得出三管塔的塔柱内力与塔架位移。通过SAP2000仿真软件建立三管塔有限元模型,利用虚面法与刚性隔板两种方法加载,分别进行三管塔结构分析。在此基础上,对不同的加载方式进行了比对。研究表明,刚性隔板法塔架位移的结果与理论值更为接近;虚面法加载时,在虚面划分合理的情况下,塔柱内力的结果更为接近理论值。
In this paper, stress and strain of a three-tube communication tower under wind load are calculated through the method of layered space truss. The finite element model of three-tube tower is built by SAP2000 simulation software and analyzed with the method of diaphragm and virtual surface. On this basis, twostructural analysis results are contrasted. The researches show that the strain using the method of diaphragm is more close to the theoretical value while the stessusing the method of virtual surface is more close to the theoretical value on the condition that the virtual surface is divided legitimately.
