摘要
为了提升桥梁抗震设计水平,总结了反应谱法和时程分析法在高烈度地区地震力分析中的应用,从抗震设防目标、地震作用分量组合、墩柱构造细节设计、减隔震设计等方面探讨了高烈度山区桥梁的抗震设计要点.同时,以某山区大跨连续刚构桥为研究对象,利用有限元软件MIDAS Civil计算了地震作用下桥梁结构的动力相应规律.
Abstract
In order to improve the seismic design level of bridges,the application of response spectrum method and time history analysis method in seismic force analysis in high intensity mountainous areas is summarized.The key points of seismic design for bridges in high intensity mountainous areas are discussed from the aspects of seismic fortification objectives,seismic action component combinations,pier column structural details design,seismic isolation design,and other aspects.At the same time,taking a long span continuous rigid frame bridge in a mountainous area as the research object,the dynamic response laws of the bridge structure under earthquake action are calculated using the finite element software MIDAS Civil.
