【摘要】：目前中小跨径装配式组合梁桥的支座形式多采用普通板式支座,其抗震效果不够理想。为了很好的满足桥梁结构抗震设计要求,同时又具有良好的经济性,本文在已有减隔震体系的基础上,提出一种新型减隔震体系,即钢阻尼滑板支座体系,该体系具有经济性和减隔震性能良好的优点。并对一实际工程的中小跨径桥梁进行了理论验证,结果表明钢阻尼滑板支座体系减隔震效果良好,可以较好的满足桥梁结构抗震设计要求,具有广阔的运用价值。
[Abstract]:At present, the support form of small and medium span assembled composite girder bridge is usually supported by ordinary plate type, and its seismic effect is not ideal. In order to meet the requirements of aseismic design of bridge structure and have good economy at the same time, based on the existing isolation system, a new type of isolation system, that is, steel damping slide bearing system, is proposed in this paper. The system has the advantages of economy and good isolation performance. The results show that the isolation effect of the steel damping slide bearing system is good, which can meet the seismic design requirements of the bridge structure and has broad application value.
