【摘要】 介绍了铁路工程抗震规范提供的钢筋混凝土桥墩延性设计计算方法;并以昆明地铁6号线某桥为工程实例,对比铁路工程抗震规范提供的钢筋混凝土桥墩延性设计简化计算方法及时程分析法,能为今后8度地震区同类桥梁设计提供一定的借鉴。更多还原

【Abstract】 This paper introduces the calculation of ductility of RC bridge piers presented in code for seismic design of railway engineering.On the base of a bridge of Kunming Urban Light Rail Line 6,the time history analysis method of ductility for bridge piers is compared with the simplified calculation method presented in code for seismic design of railway engineering.The result would provide references for the similar bridges design in future in seismic region of 8 degree.更多还原
