| Abstract: | This paper summarizes the superiority of lead-rubber bearing(LRB) continuous girder bridges.The research method for isolation performance is discussed when pile-soil interaction is considered.By the finite element method and self-compiling program,a systematic study of the reliability of LRB continuous girder bridges is given by the use of different indicators,including the riding comfort of the LRB system,the pounding and dynamic stability when the LRB system is subjected to seismic excitations,and the rel... |
