【摘要】 以西部地区某连续梁桥为例,分析了E1,E2两个设计水准地震作用下连梁装置的抗震性能。研究发现,通过在连续梁梁端设置连梁装置,可以显著降低梁端相对位移,有效减小结构关键截面的地震内力,建议在高烈度区采用连梁装置,以提高连续梁桥的抗震性能。更多还原

【Abstract】 Based on a continuous beam bridge in western region,seismic performance of unseating prevention devices was studied under seismic level E1 and E2.It was found relative displacement and seismic force of key section of structure could be effectively reduced by installing unseating prevention devices.It was suggested the unseating prevention devices should be used in the highly seismic region to improve seismic performance of continuous beam bridges.更多还原
