集成黏滞阻尼伸臂减震装置超高层建筑结构续建改造设计OA北大核心CSTPCD
Reconstruction structural design of super high-rise building with integrated viscous damped outriggers
为了在超高层建筑结构续建改造设计中减少已建结构的改造工程量,通过附加黏滞阻尼装置有效提高高层建筑在地震作用下的结构耗能,从而降低结构的内力和变形响应.研究了黏滞阻尼伸臂的变形放大原理,介绍了黏滞阻尼伸臂的最优布置方法,并提出了续建改造多状态矩阵,分析了续建改造项目典型驱动因素,总结了集成黏滞阻尼伸臂减震装置的超高层建筑结构续建改造设计策略,最后以工程实例验证该方法的有效性及准确性.结果表明:黏滞阻尼伸臂适用于以弯曲变形为主的超高层建筑结构,变形放…查看全部>>
In order to reduce the amount of reconstruction work of existing structures in the continued reconstruction design of the super high-rise building structure,additional viscous damping device can effectively improve the structural energy dissipation under earthquake,so as to reduce the internal force and deformation of the structure.In this paper,the deformation amplification principle of a damped outrigger was studied,the optimal arrangement method of the da…查看全部>>
