［摘要］“生命之環(huán)”采用空間鋼桁架+鋼筋混凝土基座的混合結(jié)構(gòu)體系,上部結(jié)構(gòu)正立面投影為豎立在地面的變截面環(huán)，環(huán)內(nèi)外輪廓為非同心圓，內(nèi)圓直徑150m，底部相切于人工湖面，外圓直徑約170m，橫截面為頂點(diǎn)朝外的正三角形。整體建筑高度約為160m，是目前世界上已建成最高的同類型構(gòu)筑物。結(jié)構(gòu)形體確定、抗風(fēng)設(shè)計(jì)、多參數(shù)化空間鋼桁架設(shè)計(jì)、施工模擬計(jì)算、鋼桁架與混凝土基座連接支座構(gòu)造以及大直徑圓鋼管相貫焊節(jié)點(diǎn)設(shè)計(jì)等均為結(jié)構(gòu)設(shè)計(jì)的重點(diǎn)和難點(diǎn)。為了檢驗(yàn)設(shè)計(jì)的可靠性，同時(shí)加強(qiáng)此類復(fù)雜工程的施工監(jiān)控，在施工和使用過程進(jìn)行了結(jié)構(gòu)健康監(jiān)測。

Abstract: The combined spacial steel truss with reinforced concrete base is adopted in the structural design of the circle of life.The shape of the front elevation of the building is a variable cross-section circle formed by two non concentric circles. The inner circle has a diameter of 150 meters, which circumscribe the lake at the foot, and the diameter of the outer one is 170 meters. The sections of the building are triangles with the angles toward outside. The circle of life is about 160 meters high, which is the highest building of this type in the world. There are several emphases and-difficulties of the structural design, including form finding, wind resistant design, multi-parameters special steel truss design, construction simulating calculation, detail design for the joint of steel truss to concrete base, mega tube multi-planar intersections joint design, etc. The structural health monitoring is carried out to validate the reliability of the structural design and monitor the site work.

Keywords: landscape building; spacial steel truss; construction simulating calculation; multiparameters design; structural health monitoring
