包头市奥体中心钢桁架简化模型的力学反应分析

Simplified model of steel truss in the olympic center of Baotou city

:对包头市奥林匹克体育中心体育场钢桁架采用空腹格构梁柱的方法进行简化计算,确定该钢桁架结构虚拟梁柱的参数,建立了一个合理的计算机模型.该模型能基本反映原桁架的截面受力和刚度,并能有效的分析结构受力情况,还能提高结构节点位移的运算精度.更加精准判断桁架的破坏位置和破坏程度.

The Olympic Sports Center Stadium in Baotou City was selected as an example to carry out the research on the method of using the hollow lattice beam column for the stadium steel truss,and the parameters of the virtual beam column of the steel truss structure were determined.A reasonable computer model was established to basically reflect the section force and stiffness of the original truss.By using this model,not only the structural stress can be analyzed effectively,but the calculation accuracy of the structural joint displacement can be improved as well,making it more accurate to judge the damage position and damage degree of the truss.Therefore,the hidden dangers in the steel truss can be found out in time to make the use of the stadium more secure.
