摘要: 珠海橫琴總部大廈龍珠項目為不規(guī)則自由曲面空間結(jié)構(gòu),結(jié)構(gòu)輪廓線采用 Grasshopper 參數(shù)化平臺找形確定,結(jié)構(gòu)布置方案采用正交網(wǎng)格形式,由 16 根放射狀分布的弓形主桿及環(huán)向的次桿組成.龍珠底部嵌固于橫琴總部大廈裙樓屋面層,建筑功能為珠海橫琴總部大廈階梯會議廳.為保證龍珠結(jié)構(gòu)的穩(wěn)定性,減小其對下部裙樓的不利影響,在龍珠底部設置雙環(huán)底盤,形成自平衡體系,采用彈簧支座的形式,并采用 MIDAS 軟件對龍珠結(jié)構(gòu)進行計算分析.分析結(jié)果表明,彈簧支座+自平衡體系可以減小地震力向下的傳遞,保證龍珠結(jié)構(gòu)的穩(wěn)定性,是類似造型結(jié)構(gòu)的理想方案.

Abstract: The pearl-shaped building of Zhuhai Hengqin Headquarters Complex is an irregular free surface space structure.The structural outline was determined by the Grasshopper parametric platform form-finding. The structural layout schemeadopts the form of orthogonal grid,which consists of 16 radially distributed arcuate main rods and circumferential secondaryrods. The bottom of the pearl-shaped building is embedded in the roof layer of the podium of the Hengqin HeadquartersComplex. The building function is the staircase conference hall of the Zhuhai Hengqin Headquarters Complex. In order toensure the stability of the pearl-shaped building structure and reduce its adverse impact on the lower podium,a double-ringchassis was set up in the form of a spring support to form a self-balancing system,and the MIDAS software was used tocalculate and analyze the structure. The analysis results show that the spring support + self-balancing system can reduce thedownward transmission of seismic force and ensure the stability of the pearl-shaped structure,which is an ideal solution forsimilar facade structures.
