摘要: 歲寶國展中心的三棟超 B 級(jí)高度塔樓,在 141m 標(biāo)高上通過兩個(gè)空中連橋相連,連橋的設(shè)計(jì)是該項(xiàng)目的重要設(shè)計(jì)難點(diǎn);三棟塔樓及連橋均不在同一條軸線上,本項(xiàng)目屬于不對(duì)稱多塔多向高位連體結(jié)構(gòu)。 系統(tǒng)論述了空中連橋結(jié)構(gòu)體系及其分析方法,提出了摩擦擺隔震支座的連接方案;全面分析了支座力學(xué)性能對(duì)豎向及水平傳力的影響,介紹了用 SAP2000 進(jìn)行連橋受力分析的方法和具體步驟。 結(jié)果表明:支座的設(shè)計(jì)可以滿足大震下受力和變形的要求,采用摩擦擺隔震支座后可顯著減少連橋與塔樓之間的相互作用,連橋設(shè)計(jì)滿足小震、中震、大震、抗傾覆等不同設(shè)計(jì)工況下的要求。

Abstract:The three towers with super-B height of SuiBao International Exhibition Center are connected by two sky corridorsat an elevation of 141m. The design of the corridors is an important design difficulty of the project. Since the three towersand the corridors are not on the same axis, this project belongs to asymmetrical multi-tower multi-directional high-levelconjoined structure. The structural system and its analysis method of the sky corridors were discussed systematically, andthe connection scheme of the friction pendulum bearing was put forward. The influence of the mechanical properties of thebearing on the vertical and horizontal force transmission were comprehensively analyzed, the method and specific steps ofusing SAP2000 to analyze the corridors force were introduced. The results show that the design of the bearing can meet therequirements of force and deformation under rare earthquakes, and the interaction between corridors and tower can besignificantly reduced by using the friction pendulum bearing. The design of the corridors can meet the requirements ofdifferent design conditions such as frequent earthquake, moderate earthquake, rare earthquake and anti-overturning.Keywords:multi-directional high-level conjoined structure; asymmetrical multi-tower structure; sky corridor; frictionpendulum bearing; mechanical parameter of bearing
