| Summary: | 碩士 === 國立臺北科技大學 === 土木工程系土木與防災碩士班 === 105 === In recent years, serious earthquakes have occurred all around the world, such as the Landers Earthquake, and Northridge Earthquake in America, the Kobe Earthquake in Japan, the Chi-Chi Earthquake in Taiwan and the Great East Japan Earthquake which caused great casualties and property losses. In view of the damage of structures and the threat of life and property caused by Fault earthquakes, the related research has been paid more and more attention by domestic and abroad scholars. Bridge plays critical role in time of any disastrous event since it is a major part of transportation, any serious damaged done to it might hinder rescue and evacuation mission.
Therefore, in this study, the simulation analysis of the creep displacement of Yu-li Bridge and Pseudodynamic test of the near-fault motions of the single-column pier are carried out. A three - dimensional finite element software program was used to establish a model of interaction between soil and the bridge structure, which the displacement behaviour of the existing bridge is considered based on the static incremental displacement analysis of the fault displacement, then response behavior of the existing bridges and the long-term creep and displacement characteristics of cross-fault bridges are studied by the experimental long-term monitoring data. In addition, a bridge specimen with different period and ductility was used as a single column specimen at the National Center for Research on Earthquake Engineering (NCREE) to study the dynamic behaviors of the bridge under the near-fault earthquake. With the expectation that engineers will be provided with comprehensive safety considerations for future design and maintenance.
