The objective of the present study is to investigate the possibility
of the application of high damping ratio structure ,by using linear fluid
dampers ,on the aseismic design and retrofitting of buildings .Factors
related to the results of the applications will be studied numerically.
Topics of study are (a) the feasibility and effectiveness of high
damping ratio structural system used in the aseismic design and
retrofitting of buildings (b) the accuracy of results by using method of
model analysis to analyze the high damping ratio buildings structure to
strong ground motions ,and (c) the influence of the stiffness of the
foundation on dynamic responses of the heavily damped building .
It is found that (a) the damping ratio of a building structure can be
largely increased by using the efficiency –enhanced damping device
systems,(b) the heavily damped building possesses high capability of
seismic resistance ,and(c) the dynamic responses of a building with
efficiency-enhanced damping device systems can be analyzed by using
the response spectrum method to obtain the conservative results for
design and retrofit of buildings if the damping coefficient of the device
systems have been adjusted following the rule proposed in the present study. |
