摘要
本文提出了一种切实有效的隔震技术,利用钢筋沥青建立隔震层,通过对试件进行振动台模拟试验,研究该隔震层在不同高度和不同台面输入加速度幅值时的减震效果;介绍了该隔震层的设计过程、施工技术要点,并通过实地试验验证其技术的可靠性和实用性。结果证明:该隔震层可以有效地折减地震作用下加速度响应,且具有施工简单、取材方便和造价低廉等特点,非常适合在全球地震区应用。
This paper proposes a practical and effective seismic isolation technology be made of steel and asphalt.To study the seismic isolation effect of the isolation layer,shaking table tests are performed for specimen heights and different acceleration amplitude input by shaking table. It introduces the design process and the construction technique about the steel-asphalt isolation layer,and field tests are performed to verify the technical reliability and usefulness. The results show that the steel-asphalt isolation layer with simple construction method,local materials and low cost can effectively reduce acceleration response under earthquake,and it is very suitable for seismic areas around the world.
