数值模拟在高耸结构设计分析中的应用

摘要

Taking the power transmission tower in coastal region as the original model,the paper analyzes the ultimate bearing capacity of the structure under wind load by applying numerical simulation method. Results show that:the dynamic wind load increasing effect owing to high and strong typhoon turbulence must be taken into consideration of power transmission tower design in typhoon region;furthermore,numerical simulation is an economic method used in high-rise structure design analysis.%以沿海地区某输电塔结构为原型，采用数值模拟的方法对结构在风荷载作用下的极限承载力进行了分析，结果表明：台风多发地区的输电塔设计必须考虑台风高湍流引起的动力风荷载增大效应，并指出数值模拟是高耸结构设计分析中经济有效的方法。
