苏州工业园区档案管理中心各功能单体外化为棱柱、立方体、平板等几何体,似多块积木重叠错落搭建而成,属结构平面及竖向特别不规则、结构体系复杂、多项超规超限的建筑。本工程通过沿大跨悬挑块体的支撑体四周设置“环绕型内置式防震缝”化繁为简,将结构划分为3个独立的抗震单元,并且在薄弱部位设置防屈曲耗能减震支撑,减小地震反应。设计中对整个建筑进行动力弹塑性分析,并且对大悬挑空间桁架的方钢管相贯节点进行了有限元分析和试验验证,保证了整个设计项目的安全可靠,经济效果显著。
Suzhou Industrial Park Archive Management Center of the monomer into a prism, cube, plate and other geometric body, like a number of pieces of building blocks overlapped and scattered from the structure plane and vertical is particularly irregular, complex structural system, a number of ultra-super-ultra Limited building. The project divides the structure into three independent seismic units by setting “surround-type built-in anti-vibration seams” around the support body of the large-span suspension block, and sets the anti-buckling energy dissipation in the weak part Shock absorption support reduces earthquake response. The design of the entire building for the dynamic elasto-plastic analysis, and the large cantilevered space truss of the square steel pipe joints have been conducted by finite element analysis and experimental verification to ensure the safety of the entire design project, the economic effect is remarkable.
