钢管混凝土系杆拱桥的有限元抗震分析
|
摘要
近年来,全球地震频繁发生,严重地危害着人民的生命和财产的安全。刚刚发生的5.12汶川大地震破坏了大量的作为生命线工程的桥梁,对抢救工作带来了极大的困难,使许多生命因此罹难。在地震作用下,作为生命线工程之一的桥梁结构的破坏,将加重次生灾害的程度,导致更为严重的生命财产及经济损失。为此,有必要掌握和理解桥梁的地震反应,建立合理抗震体系,采取有效的抗震措施。该文在简述结构动力特性与地震反应分析的基本理论基础上,对某铁路钢管混凝土系杆拱桥进行了自振特性分析、稳定分析、地震反应谱分析和地震反应时程分析。主要研究内容包括:第一,建立完善的桥梁计算模型;第二,进行结构的自振特性分析和稳定分析,并考虑了桩-土相互作用对桥梁自振特性的影响;第三,考虑纵桥向和横桥向反应谱输入,对桥梁进行了地震反应谱分析。第四,考虑纵桥向+竖向地震动输入与横桥向+竖向地震动输入,对桥梁进行了动态时程分析,并考虑了行波效应的影响。
In recent years, the world's earthquakes happen frequently and endanger people's lives and property seriously. The 5.12 Wenchuan earthquake Which has happened just now damaged a large number of bridges as a life-line engineering.It brings numbers of difficulties for rescue and so much the victims. the destruction of the bridge, as one of lifeline engineering , will increase the extent of secondary disasters, leading to more serious life and property and economic losses. Therefore, it is necessary to grasp and understand the seismic response of the bridges, set up a reasonable system and take effective anti-seismic measures. This paper,basing on the basic theory of a brief structural dynamic characteristics and seismic response analysis, carries out the analysis of the self-vibration characteristics , stability ,the spectrum and time-history of earthquake response.The Main research contents include: First,setting up a perfect calculation model of the bridge;Second,carrying out the analysis of the self-vibration characteristics and stability and considering the pile - soil interaction on the effects of self-vibration characteristics of the bridge; Third, considering the spectrum input of the the longitudinal and cross-bridge and carring out the spectrum analysis of seismic response of the bridge. The fourth,considering the longitudinal-bridge and vertical ground motion input and cross-bridge and vertical ground motion input and carrying out the time-history analysis and considering the traveling wave effects.
