ABSTRACT
ABSTRACT: The influence of temperature to the long-span multiple bar steel structural transmission tower of through various aspects is joint action. The influence of different connection, span number and temperature is different. In order to study the mechanics and deformation characteristics of the large statically indeterminate tower structure on temperature load, ANSYS software is used to establish the large span steel structure model of the transmission tower system and the deformation and internal force of the most adverse conditions are obtained under different temperature load and gravity. Further the safety factor and the relative deformation are defined here to analyze the strength security and stability of the tower components.
