| Abstract: | Computer program for dynamic analysis of a structure including a Maxwell damping unit in itself as well was developed with Fortran and the damping effect of the damper on the anti-seismic performance of continuous girder bridges was investigated.It was shown by the investigation that the seismic response of the constructure could be decreased by using the damper,so that the distribution of inner force in the bottom of bridge pier was made uniform,benefiting the anti-seismic design of the structure.When the parameters of the damper was selected reasonably,a good damping effect of the structure of continuous girder bridge could be obtained with the help of Maxwell model damper. |
