摘要:
利用有限元法建立大跨度钢管混凝土拱桥的结构模型,计算其自振性能,应用时程分析法,计算该桥考虑吊杆张力和拱肋初始应力影响的动力特性和地震响应,并与不计吊杆张力和拱肋初应力影响的桥梁动力特性和地震响应进行了比较,分析了该拱桥的结构抗震反应.结果表明,初始应力对于拱肋的力学性能影响不大,并满足设计要求,本桥抗震性能良好.
Abstract:
According to the structural feature of the bridge，spatial finite element analysis model is established to calculate its natural vibrations，by use of the seismic time—history response，dynamic characteristics and the seismic responses derived from history analysis are analyzed and compared whether under initial stress or not．The results show that the response of initial stress do not have too much effect on the bridge．The anti—seismic capability of the bridge is good．
