摘要
高耸结构对风荷载比较敏感,在以风荷载为主的荷载作用下,对结构的变形有着严格的要求,特别是某些具有特定使用功能的自立塔结构,塔顶设置标校设备来接收天线进行联调或指标测试,需保持塔顶的稳定,因此对风荷载作用下的塔顶变形要求更为严格.本文主要以工程中某自立塔塔顶位移的优化为主要研究对象,分析结构在风荷载作用下的顶部变形控制因素.对比分析通过增大结构刚度、改变塔体使用材料、增加辅助杆件等措施对塔顶部变形量的影响,选取出最经济、有效的控制变形方法来达到使用要求.
Abstract
High-rising structures are particularly susceptible to wind loads.Under predominantly wind-in-duced loads,strict requirements are set for the deformation of these structure,especially for self-supporting tow-er structures with specific functional purposes.Typically,these towers are equipped with calibration devices on top to receive antenna signals for alignment or performance testing.Therefore,the requirements for top deforma-tion under wind loads are even more stringent.This paper primarily focuses on optimizing the top displacement of a self-supporting tower in real engineering.The factors influencing the top deformation of the structure under wind loads are analyzed.By comparing and analyzing the impact of measures such as increasing structure stiff-ness,altering tower materials,and adding auxiliary rods,the most economical and effective deformation control measures to meet the application requirements is selected.
