| Summary: | 碩士 === 雲林科技大學 === 營建工程系碩士班 === 96 === In the initial stage of the seismic-isolation concept used for bridge design, only traffic direction of the bridges were considered to adopt the new design concept so the dynamical behavior was simple but the mitigation of seismic effect was limited. Later, the concept was extended to the transverse design of the bridge and then the behavior became more complicate. When the concept was used in transverse design of the bridge in Taiwan the girder was constrained at both ends in order to make the behavior simpler as well as to use the traditional expansion joint. To investigate the dynamical characteristics and response of the isolated bridges partially constrained, the method of virtual work was applied in this study to attain the approximate solution of the fundamental period of the flexural vibration of the bridges in different assumptions of the boundary condition at the both ends of the girder, which is used to.
