［摘要］貴陽未來方舟項(xiàng)目D1地塊塔樓為大底盤多塔結(jié)構(gòu)，塔樓在31～34層處有12-6m高的連接體結(jié)構(gòu)，屬于連體-多塔結(jié)構(gòu)。根據(jù)平面分布特點(diǎn)，塔樓與連接體之間設(shè)置8個(gè)橡膠支座實(shí)現(xiàn)柔性連接。介紹了橡膠支座選型、連接體及樓蓋的設(shè)計(jì)、支撐連接體的懸挑梁設(shè)計(jì)，并復(fù)核大震下橡膠支座變形能力。進(jìn)一步研究表明，含與不含連接體塔樓抗震性能幾乎相同。此外，進(jìn)行了多塔與單塔的結(jié)構(gòu)抗震性能比較，并考察了不同地震輸入角對(duì)結(jié)構(gòu)抗震性能的影響，結(jié)果表明，本工程的結(jié)構(gòu)設(shè)計(jì)可直接基于不含連接體的整體模型（模型中將連接體簡(jiǎn)化為重力荷載），并以施加多個(gè)水平附加角來模擬不同地震輸入角的影響。

Abstract:The structure of the proposed building in D1 Plot of  Ark for Future Project in Guiyang is multi-tower with large chassis and a 12-6m connecting structure from 31st to 34th floor, which helongs to a multi-tower connecting structure. According to the planar distribution characteristics, eight rubber bearings were designed to be set between the tower and the connection to achieve a flexible connection.  Firstly, the selection of rubber bearings, the design of connection and floor and the design of cantilevered beam which supports the connection were introduced. And then, the deformation ability of rubber bearings under rare earthquake was reviewed. Further studies show that the seismic performances of tower models with or without connecting structure are almost the same. In addition, structural seismic performances of the single tower and multi-tower were compared and the influences of different earthquake input angles on structural design were investigated. The results show that the structural design of the project can be directly applied based on the whole model without connection structure which is simplified as weight in the model. Also, a plurality of additional horizontal angles  exerted to simulate the influence of different earthquake input angles.

Keywords:multi-tower with large chassis; flexible connection; multi-tower connecting structure; seismic behavior; earthquake input angle
