摘要: 兩棟形體不對(duì)稱塔樓在高位通過空中連廊連接為整體結(jié)構(gòu)。 連接體一層是觀光平臺(tái),二層是室外游泳池,因?yàn)樗切误w不對(duì)稱,連接體平面位置偏置,并且游泳池的設(shè)備管線只從一側(cè)塔樓進(jìn)出,造成兩側(cè)變形縫的性能需求不一致。 連接體的一側(cè)變形縫設(shè)置較柔的摩擦擺隔震支座,通過較大的位移釋放支座水平反力;另一側(cè)設(shè)置較剛的摩擦擺隔震支座和黏滯阻尼器,以改善設(shè)備管道的抗疲勞性能,從而能更合理地滿足安全性和使用性需要。對(duì)連體結(jié)構(gòu)雙塔進(jìn)行動(dòng)力彈塑性分析,對(duì)不同參數(shù)隔震支座的選型、摩擦擺隔震支座最大矢量位移、豎向作用力對(duì)摩擦擺隔震支座的影響等幾個(gè)相關(guān)問題進(jìn)行了分析。 結(jié)果表明,根據(jù)性能需求的差異而選定的隔震支座參數(shù),可以更好地匹配建筑功能,且具有足夠的安全儲(chǔ)備。

Abstract: The two asymmetrical towers are connected by the air connective corridor to form a whole structure at a high level.The first floor of the connective corridor is a sightseeing platform, and the second floor is an outdoor swimming pool. Becausethe shape of the tower is asymmetrical, the plane of the connective corridor is offset, and the equipment pipelines of theswimming pool only enter and exit from one tower, resulting in inconsistent performance requirements of the deformation jointson both sides. One side of the connective corridor was provided with a relatively soft friction pendulum vibration isolationbearing, which releases the horizontal reaction force of the bearing through a large displacement; The other side was providedwith a relatively rigid friction pendulum isolation bearing and a viscous damper to improve the anti?fatigue performance ofequipment pipelines, so as to meet the needs of safety and usability more reasonably. The dynamic elastic?plastic analysis ofthe conjoined twin towers was carried out, and the selection of the isolation bearing with different parameters, the maximumvector displacement of the friction pendulum isolation bearing, the influence of vertical force on the friction pendulum isolationbearing, etc. were analyzed. The results show that the seismic isolation bearing parameters selected according to thedifference of performance requirements can better match the building function and have sufficient safety reserves.
Keywords:conjoined structure; isolation design; parameter asymmetry; friction pendulum isolation bearing; viscous damper; maximum vector displacement
