支座摩阻效应对大跨长联连续梁桥地震反应的影响分析OA北大核心
Analysis of Sliding Bearing Friction Effect on Seismic Behavior of Long and Large-Span Continuous Bridges
为了解支座摩阻效应对长联大跨连续梁桥地震反应的影响,并得出可应用于工程的相应简化计算方法,以处于高烈度区的某铁路大跨长联连续梁为工程背景,按照不计与计入活动支座摩阻效应两种工况,利用Midas/Civil软件建立结构的三维空间杆件模型,并选用软件中的两种双线性理想弹塑性单元模拟支座的摩阻,采用非线性时程分析方法,对结构进行多遇地震下的地震反应分析.分析结果表明,对于这种设置1个固定墩的大跨长联连续梁结构,是否计入活动墩的支座摩阻效应对固定墩的设计…查看全部>>
With reference to a long and large-span continuous bridge used in a high-intensity area, a three-dimensional space model of the structure is established with Midas/Civil software to understand the effect of bearing friction on the seismic response of the bridge,and to obtain the corresponding simplified calculation method applicable to engineering according to two kinds of working conditions about the sliding bearing friction. Two bilinear ideal elastic-plas…查看全部>>
