摘要

为了解干字形角钢输电塔在地震作用下的特点和规律,以某大跨度输电塔为实际工程背景,基于空间梁单元建立了输电塔的力学模型,并选取典型地震波进行计算分析,观察输电塔4条塔腿相同位置主材杆件的轴应力峰值响应和塔顶位移响应。研究表明:输电塔4个塔腿主材杆件的轴应力响应,在不同方向地震波作用下存在较大的差别,而塔顶基本相同。
For understanding characteristics and laws of gan typed angle iron transmission tower under the force of earthquake,this paper takes one long-span transmission tower as practical engineering example and establishes mechanical model based on spatial beam unit.It chooses typical seismic wave to carry out calculation and analysis and observes axial peak stress response and tower top displacement response of principal material bars in the same position of four tower legs.The study shows that axial stress responses of principal material bars are comparatively different under force of seismic waves in different directions while same in tower top.
