【摘要】 以一座三跨小箱梁连续梁桥为计算对象,分别在Midas和Sap2000有限元软件中对其进行反应谱分析、延性设计弹塑性分析和隔震设计弹塑性分析。分析结果表明,二者的反应谱分析结果比较接近,Sap2000的弹塑性分析结果均比Midas的结果偏小。研究成果可为同类桥梁抗震分析提供参考。更多还原

【Abstract】 A three-span small box girder continuous bridge is taken as a calculation model in Midas and Sap2000 finite element software for spectrum analysis,elastic-plastic analysis of ductility design and elastic-plastic analysis of isolation design.The results demonstrate that the spectrum analysis results of the both are more closely,and the elastic-plastic analysis result of Sap2000 is relatively smaller than that of Midas,and may serve as reference for seismic analysis of the similar bridges.更多还原
