摘要:
为了解决隔震桥梁的梁体和支座位移在近断层地震激励下易超出容许值的问题,提出了基于混合罚函数理论的隔震支座参数优化方法。以四跨铅芯橡胶支座(LRB)隔震高架连续梁桥为背景,制作了该背景的1∶10缩尺模型桥,开展了模型桥振动台台阵试验。基于混合罚函数理论编制了用于优化LRB屈服力、初始刚度和硬化比的MATLAB程序,并分别对优化前后的模型桥在单条或多条地震激励下的响应进行了仿真和试验分析。结果表明:模型桥在优化前后的响应仿真值与试验值非常接近;多条地震激励下的目标函数值要比单条地震激励下的略大一些;优化后的模型桥在单条和多条地震激励下的梁体和支座位移均在容许值内,且各墩底内力均未明显增大.
