大型浮顶罐抗风研究现状与分析

摘要

Large metal storage tanks is vulnerable to storm damage , it is necessary to conduct the thorough research to the wind resistance stability of the tank .Wind tunnel test and numerical simulation method to study the wind pressure distribution of tanks were introduced .The advantages and disadvantages and research status of the two methods were analyzed .The wind-induced buckling method used to study the stability of tank under wind load was illustrated .The characteristics and applicable conditions of the two common finite element softwares ABAQUS and ANSYS were compared to provide reference to wind resist -ance design of the tank .%大型金属储罐易遭受风灾破坏，有必要对储罐的抗风稳定性进行深入研究。文中介绍了研究风压在储罐上分布的风洞试验方法和数值模拟方法，分析了二者的优缺点和研究现状。介绍了用来研究储罐在风荷载作用下稳定性的风致屈曲分析方法。比较了2种常用有限元软件（ ABAQUS和AN-SYS ）的特点及适用条件，为储罐的抗风设计提供参考。
