摘要
文章根据当前的桥梁抗震处理需求,标定抗震点,采用多层级结构,扩大覆盖加固范围,实现多层级加固处理效果。在此基础上,建立了带黏滞阻尼器的桥梁有限元抗震计算模型。分析结果表明,对比传统技术,文章所述技术有效降低了桥梁的地震响应荷载,这说明黏滞阻尼器在桥梁抗震中的应用效果更好,实际应用价值更高。
According to the current demand for bridge seismic treatment,this paper calibrates seismic points,adopts multi-level structure,and expands the coverage and reinforcement range to realize the eff ect of multi-level reinforcement treatment.On this basis,the finite element seismic calculation model of bridge with viscous damper is established.The analysis results show that compared with the traditional technology,the technology described in this paper eff ectively reduces the seismic response load of the bridge,which indicates that the application eff ect of viscous damper in bridge seismic resistance is better and the practical application value is higher.
