At first in the preliminary design this paper computes the linear damping coefficient of the viscous damper employed in this project using Composite Response Spectra approach, meantime, this paper proves that reducing the exponent of velocity of the piston can increase the magnitude of the dissipative energy, because of the viscous damper employed in the practical project character nonlinear behavior; next this chapter performs analysis and comparison between the building without and with the viscous dampers aforementioned when the building suffers from various Time Domain Response, from the angle of displacement, interstroy drift, velocity, interstory velocity, acceleration, energy, maximum axial force of the dampers and of the column etc., in order to prove that the incorporating the viscous dampers into the buildings has great superiority on enhancing its aseismic performance ; furthermore, this chapter also expatiates on diverse assembly form of the viscous dampers that results in the adverse impact on the internal force of the structural member in this building, on the ground of which this segment bring about the preference of the assembly form of the viscous damper; finally this chapter points out the sphere of application of the analysis and computation using Composite Response Spectra approach in design: it is available in well-proportioned stiffness structures and isn抰 available in the structures that contain weak story. It is recommendable, particularly, to incorporate the fluid viscous dampers into this structure that contain weak story to refrain earthquake and reinforce, such as the Central Hall of Shanghai Exhibition Hall.

首先使用了反应谱分析法设计出欲附设的粘滞阻尼器的线性阻尼系数，由于实际工程所用的粘滞阻尼器具有非线性的特性，故而笔者又证明了降低速度指数对提高粘滞阻尼器的耗能量的优势所在；接着分别从位移、层间位移、速度、层间速度、加速度、能量、最大阻尼出力和柱轴力等不同的角度对结构在附设粘滞阻尼器前后的时程反应进行了分析对比，籍此在实际工程中证明了附设粘滞阻尼器对于提高结构的抗震性能的优越性；再者，笔者还阐述了采用不同的粘滞阻尼器布置方式对结构中构件内力特别是柱轴力和基座竖向反力产生的不利影响，并在此基础上提出了布置方式的优选；最后，指出了反应谱法在设计中的适用范围：对于均匀结构反应谱法能够使用，而对于含有薄弱层的结构反应谱法并不适用；对于类似于上海展览馆中央大厅的含薄弱层的结构尤其值得使用粘滞阻尼器的方法进行抗震加固。
