本文在前人对刚体碰撞模型所作分析的基础上,以简支梁桥为研究对象,建立了考虑横向碰撞的简化模型。通过量化挡块碰撞刚度、初始间隙对简支梁桥地震碰撞响应的影响,探讨了桥梁抗震挡块的抗震效果,得出简支梁桥抗震挡块的最优参数,供梁桥抗震设计及规范修编参考。
Based on the previous analysis of the rigid-body collision model, a simplified model considering lateral collision is established based on the simple-supported beam bridge. By quantifying the influence of the impact stiffness and the initial clearance of the stop on the seismic response of a simply supported beam bridge, the aseismic effects of the seismic block of the bridge are discussed. The optimal parameters of the seismic block of the simply supported beam bridge are obtained, Normative references.
