摘要:
为了提高铁路房屋的抗震能力，分析地震动竖向分量对铁路房屋的地震响应性能，提出基于荷载—变形关系联合评估的地震动竖向分量对铁路房屋的地震响应评估模型。构建地震动竖向分量的力学响应评估模型，识别铁路房屋的地震屈服响应参数，采用荷载—变形关系和极限荷载结合的方法进行铁路房屋的地震屈服响应应力评估，分析地震动竖向分量对铁路房屋的响应。建立动量平衡方程和弯矩平衡方程，构建铁路房屋的地震响应的三阶段荷载—变形模式，实现地震动竖向分量对铁路房屋的地震响应性能评估模型的优化设计。测试结果表明，采用该模型能有效分析地震动竖向分量对铁路房屋的地震响应性能影响，Simulink仿真结果和有限元模拟结果的准确性较高，力学参数辨识性能优越，计算结果准确可靠。
Abstract:
In order to improve the seismic capacity of railway buildings，effect of vertical components of ground motion on seismic response of the buildings is analyzed，and an evaluation model of seismic response of railway buildings based on joint assessment of load-deformation relation is proposed. The mechanical response evaluation model of vertical component of ground motion is constructed，the seismic yield response parameters of railway buildings are identified，and the seismic yield response stress of railway buildings is evaluated by the combination of load-deformation relation and limit load. The response of vertical component of earthquake ground motion to railway building is analyzed. The momentum equilibrium equation and bending moment equilibrium equation are established to construct the three-stage load-variation of earthquake response of railway buildings and to optimize the evaluation model of seismic response performance of railway buildings with vertical components of ground motion. The test results show that the model can effectively analyze the effect of vertical component of ground motion on seismic response of railway buildings. Simulink simulation results and finite element simulation results have higher accuracy，superior identification performance of mechanical parameters and accurate and reliable calculation results.
