摘要

鉴于输电铁塔单变双角钢转换节点基础理论和设计规范的欠缺

开展单变双角钢转换节点承载力的数值仿真和设计理论研究。对工程常见构型的单变双角钢转换节点进行有限元建模及其仿真计算分析

探究该节点在受拉、受压荷载条件下的受力机理和破坏模式

以此获得转换节点各部件(上单角钢、下双拼角钢、上下靴板以及水平过渡板)匹配设计基本原则

为提出设计推荐公式提供重要依据; 基于屈服线法理论提出单变双角钢转换节点整体承载力设计推荐公式

并借助“塑性分析

弹性设计”的思想对承载力的预测考虑合理的安全储备

便于工程设计; 采用屈服线法设计公式和现行相关设计公式对相同构型的单变双角钢转换节点分别进行承载力计算。对比结果表明

屈服线法设计公式计算结果与有限元仿真最为接近

平均相差仅为0.82%

能较好地反映单变双角钢转换节点的整体承载力。研究成果可对现行设计规范及理论提供参考。

Abstract

Conversion joints between single-angle and dual-angle steels are widely applied in steel pylons. Aiming at the lack of related basic theory and design specifications

the bearing capacity of conversion joints between single-angle and dual-angle steel is investigated via numerical simulation. Nine common-si-ed conversion joints are taken as the simulation examples with finite element method(FEM)

and their stress state and failure mode under static tension and compressive loadings are discussed. Several design principles of component match are obtained to provide the crucial basis for the recommended design formula

the components include top single-angle and bottom dual-angle steel

vertical plates

and hori-ontal plate. The recommended design formula are then presented to evaluated the bearing capacity of conversion joints following yield line theory(YLT). It is convenient to reasonably consider certain safe reservation in virtue of the idea of -plastic analysis and elastic design-
