高大超长单层钢结构刚架温度分析及优化设计

Temperature Analysis and Optimal Design of Rigid Frame of Tall Extra-Long Single-Layer Steel Structure

通过对某高大超长单层钢结构厂房建筑的主刚架进行温度作用计算及对比分析,解决了高大超长刚架结构设计的温度影响问题,分析了温度作用、风荷载对高大超长单层钢结构刚架设计的主要影响,并根据主要影响因素探讨了不同的结构方案,提出了高大超长单层钢结构刚架的优化设计思路。

Through the calculation and comparative analysis of temperature action on the main rigid frame of a tall and ultra-long single-storey steel structure factory building,the temperature influence problem of the design of tall and ultra-long rigid frame structure is solved.The main influence of temperature action and wind load on the design of tall and ultra-long single-storey steel structure rigid frame is analyzed,and different structural schemes are discussed according to the main influencing factors.The optimal design idea of tall and extra-long single-layer steel structure rigid frame is presented.
