摘要
介绍了重庆江北机场新航站楼主楼钢结构方管主桁架的模型试验研究。试验模拟了实际结构主桁架和其侧向支撑 ,研究其在不利工况下的内力和变形 ,试验结果和线性有限元数值分析对比符合较好 ,并表明所设计的桁架能满足工程要求。对试验结果的进一步非线性有限元分析表明 ,主桁架的侧向支撑效应将对其稳定和承载力产生较为显著的影响。
The experimental research on the model of steel t russ with rectangular tube members for new terminal building of Chongqing Jiangb ei Airport is reported. The main truss and the lateral braces were simulated in the test. The results of linear finite element analysis match the experimental r esults well both in interior forces and deformations. It is also shown that the designed truss can meet the demands of capacities and stiffness. The further non linear analysis shows that lateral braces have obvious effects on bearing capaci ty of the main truss.
