摘　　要：对一种普通装配整体式框架结构与配置黏滞阻尼器的装配整体式减震框架进行了动力试验与有限元对比分析研究,试验与有限元结果吻合较好,并对普通装配式框架与装配式黏滞阻尼器减震框架进行对比分析,在此基础上进行拆除黏滞阻尼器的带连接墙的装配式框架与黏滞阻尼器跨内不同布置位置的参数影响分析研究。结果表明:黏滞阻尼器在装配式框架中具有良好的减震效能,且能够延缓梁端塑性铰的开展,而阻尼器连接墙的存在可以提高框架的刚度,但会削弱构件的最大承载力。黏滞阻尼器在跨中与跨边布置均能有效提高结构承载力,其中跨内中部布置黏滞阻尼器相较于端部阻尼器布置能够更好地发挥减震效能,说明黏滞阻尼器在端部布置削弱了装配式黏滞阻尼器减震框架的承载力,该研究可为装配式结构减震方案优选提供帮助。The dynamic test and finite element comparative analysis of a common precast monolithic frame structure and a precast monolithic damping frame with a viscous damper are carried out.The test results are in good agreement with the finite element results.The common precast frame structure and the precast damping frame with the viscous damper are compared and analyzed.On this basis,the parametric analyses are carried out to evaluate the effect of the existence of the damper connection wall and the installation location of the viscous damper.The results show that the viscous damper has a good damping effect on the precast frame and can delay the development of plastic hinges in beam ends.The existence of the damper connection wall enlarges the stiffness of the frame but weakens the maximum bearing capacity.The viscous damper effectively improves the bearing capacity of the specimens,while being mounted in the middle of the span is more effective than the end arrangement method,which shows that the arrangement of the viscous damper at the end weakens the bearing capacity of the precast frame with a viscous damper.This study can provide help for the optimization of the damping scheme of the precast structure.
