【摘要】 针对木框架结构的特点研发了一种新型粘弹性角位移阻尼器,并对安装了新型粘弹性角位移阻尼器的2层木框架结构进行了振动台试验及数值模拟,与未加阻尼器的木框架进行了对比分析。结果表明:新型角位移阻尼器能够给结构提供一定的刚度和阻尼,并有效减小结构的位移和加速度反应,提高木框架结构的抗震能力;在计算粘弹性阻尼结构的动力反应时,采用Wen模型可以很好地模拟阻尼器对结构的控制作用。更多还原

【Abstract】 According to the characteristics of the wood frame structures,a new viscoelastic angle-displacement damper was put forward,and the shaking table tests and numerical simulations of two-floor wood frame structures with the new viscoelastic angle-displacement damper were carried out.Furthermore,the wood frame structures with and without dampers were comparatively analyzed.Results show that the new angle-displacement damper can increase the stiffness and damp of structure,decrease the displacement and acceleration reaction effectively,and improve the seismic capacity of wood frame structures;Wen Model can simulate control action of damper on structure well during the calculation of dynamic reaction of viscoelastic damping structures.更多还原
