摘要
海南中学综合艺术楼为大跨度钢筋混凝土框架结构,采用基础隔震技术,隔震层位于连接上部结构的斜板和地下室顶板之间。该结构前三层均存在柱距大于30 m的大跨度,最大柱间距超过45m。由于柱距过大,且还要考虑地震作用下隔震层的移动空间,难以设置统一的隔震层。经过分析,在高于室外地坪1.3 m处设置整块斜板来连接上部结构,并在该板下端设计了一系列尺寸不同、位置不同的上下支墩来布置隔震支座,隔震效果较好。
Hainan middle school integrated art building is a large span reinforced concrete frame structure,using the base isolation technology, and the isolation layer is located between the upper structure and the basement roof. The structure of the first three layer are greater than the column span of 30 meters, the maximum column spacing of more than 45 meters.As the column spacing is too long and also consideration the mobile space for isolation layer under the earthquake that it is difficult to set up a unified isolation layer.After detailed analysis, set a whole piece of inclined plate links the upper structure higher than the outdoor terrace at 1.3 meters and design a series of different sizes and different position prop up and down to arrangement of isolation bearing in the lower end plate,and then showing good isolation effect.
