摘要:
上海浦东机场T2航站楼结构为复杂大跨混合结构,本文采用NosaCAD2005有限元程序建立结构分析模型,模型主要由非线性杆单元组成,包括梁、柱和二力杆单元,梁、柱采用三段变刚度杆模型,以受弯为主的梁单元截面弯矩-曲率关系采用二折线和三折线模型,柱和二力杆截面采用纤维模型.通过多遇和罕遇烈度下的弹塑性时程分析,研究了该结构的变形、内力、破坏情况的发展历程.计算结果表明,该结构可以满足“小震不坏,大震不倒”的设防要求.
Abstract:
The T2 building of Shanghai Pudong International Airport is a complex long-span spacial hybrid structure.Using NosaCAD2005,the structural analysis model,mainly composed of beams,columns and trusses,is established.Beams and columns are combined with three different stiffness segments.The beams mainly bear moment.The bilinear and tri-linear moment curvature hysteretic models are employed to simulate the behavior of nonlinear segments,while fiber model is employed to simulate the behavior of nonlinear segments of columns and trusses.The elasto-plastic time history analysis is carried out to study the seismic behavior of the structure under the frequent and rare intensity earthquakes.Based on the analysis,the deformations,internal forces and damage patterns of the structure are investigated.The results show that the structure can meet the code requirements of no damage under frequent earthquakes and without collapse under rare earthquakes.
