The Direct Displacement-Based Design (DDBD) method has become a popular seismic design tool for structures. It takes drift as the performance criterion while designing structures. This method overcomes the shortcomings of the traditional force-based seismic design method, which considers peak force as the design parameter. In terms of structural damage, deflection is a better indicator, and hence, DDBD is a more acceptable method for seismic design. In this paper, a 12-story RC frame building with supplemental damping has been designed and investigated using a direct procedure of calculation, while considering the displacement-based design method. The performance of building with and without viscous dampers for a particular performance level has been compared. The effects of the non-linearity of dampers have also been discussed, and the effect of constant and story proportional drift proportional damper forces have been investigated. The results of various cases have been compared. It has been found that drift proportional story shear proportional carried damper design leads to construction economy.

Bridge is an important part of transport system, especially for the long-span bridges of important route. And it belongs to the lifeline project. It is an important measure for reducing the secondary disaster to ensure bridge’s normality in traffic after the earthquake. Currently, the isolation seismic design of long-span bridges with the special structure is used to reduce damage of bridges by the reason of the earthquake. Based on damping principle of the viscous dampers, the calculation and analysis of what the effect of shock absorption done by damper in decorate position of long-span cable-stayed bridge to structure of bridges are formulated in this paper.
