SEISMIC RESPONSE ANALYSIS OF HIGH-PIER AND LONG-SPAN CONTINOUS RIGID-FRAMED BRIDGE UNDER NON-UNIFORM EXCITATION

摘要

Taking the Longtan River Bridge as the engineering background , the seismic response analysis of high-pier and long-span continuous rigid-framed bridge considering travelling wave effect is simulated by means of the great mass method. Conclusions are drawn under asynchronous and synchronous excitation respectively , between which comparison indicates that the seismic responses for the main beams of continuous rigid-framed bridge are decreased at various degrees , such as the longitudinal horizontal displacement. The travelling wave effects on the piers are also related to the characteristics and locations of the bridge piers and so on .
