摘要:

我國地域遼闊，許多地區(qū)位于地震帶上，采用隔震技術(shù)提高建筑物、橋梁等的抗震能力以避免和減少地震事件后人民生命財產(chǎn)損失，具有重大意義。應(yīng)用天然橡膠制備的隔震支座，具有很好的豎向剛度和水平等效剛度，但等效阻尼比非常低，需要增加另外的阻尼器或灌注鉛芯來提高阻尼比。為了解決這一問題，工程技術(shù)人員通過共混、共聚、添加小分子等方式制備具有優(yōu)異綜合力學(xué)性能和阻尼性能的橡膠復(fù)合材料，并將其應(yīng)用在隔震體系中，促進了隔震技術(shù)的發(fā)展。介紹了隔震技術(shù)的原理和分類，特別是疊層橡膠支座隔震體系的分類和研究現(xiàn)狀。綜述了隔震支座用橡膠復(fù)合材料，包括：單一組分橡膠、多元組分橡膠、有機小分子雜化材料、磁流變彈性體等的研究現(xiàn)狀和應(yīng)用情況。

Abstract:

Many areas of China are located in the seismic zone, the use of isolation technology to improve the seismic capacity of buildings or bridges for avoiding and reducing the loss of people�餾 lives and property after the earthquake is of great significance. Natural rubber bearings has good vertical stiffness and shear stiffness, but the equivalent damping ratio is very low, and additional dampers or infused lead cores are needed to increase the damping ratio. In order to solve this problem, engineers are developing rubber composites with excellent comprehensive mechanical properties and damping properties by blending, copolymerizing and adding small molecules, and widely using them in isolation systems, which greatly promotes the development of isolation technology. This paper firstly introduces the principle and classification of the isolation technology, especially the classification and current status of the laminated rubber bearing isolation system. Finally, the rubber composite materials for seismic isolation bearings are reviewed, including the research status and application of single component rubber, multicomponent rubber, organic small molecular hybrid materials and magnetorheological elastomers.
