新型伸臂消能体系的抗震性能研究

摘要

以天津某实际工程项目为例,对新型伸臂消能结构体系中消能伸臂的数量、位置和黏滞阻尼器参数进行了优化,比较了这一新型消能体系与常规消能减震方案的减震效果.研究表明,相对于常规消能减震方案,新型伸臂消能结构体系可在布置较少数量阻尼器时,仍获得较好的减震效果,其经济性十分明显,可望在实际工程中进一步推广应用.%In this paper, the number and position of outriggers and parameters of viscous dampers are investigated and optimized for a real high -rise building with novel damped outriggers in Tianjin. The paper compares seismic performance of the new damped outrigger system with that of the traditional energy dissipation system by the numerical simulation. Results show that the new damped outrigger system can greatly improve the seismic performance of high-rise building with a relatively small amount of viscous dampers. Thus, it is worthwhile to popularize and apply the new damped outrigger system in practical civil projects.
