【摘要】：目前中小跨徑裝配式組合梁橋的支座形式多采用普通板式支座,其抗震效果不夠理想。為了很好的滿足橋梁結(jié)構(gòu)抗震設(shè)計(jì)要求,同時(shí)又具有良好的經(jīng)濟(jì)性,本文在已有減隔震體系的基礎(chǔ)上,提出一種新型減隔震體系,即鋼阻尼滑板支座體系,該體系具有經(jīng)濟(jì)性和減隔震性能良好的優(yōu)點(diǎn)。并對(duì)一實(shí)際工程的中小跨徑橋梁進(jìn)行了理論驗(yàn)證,結(jié)果表明鋼阻尼滑板支座體系減隔震效果良好,可以較好的滿足橋梁結(jié)構(gòu)抗震設(shè)計(jì)要求,具有廣闊的運(yùn)用價(jià)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.
