［摘要］正佳極地海洋世界生物館項目是在已運營商業(yè)建筑中建設(shè)海洋館的特殊改造工程，海洋館在既有建筑中增加10萬kN的荷載，并需切除部分樓層的少量框架柱。結(jié)構(gòu)改造設(shè)計中充分考慮了海洋館的特殊建筑功能及新增重載的要求，采用從整體到構(gòu)件的加固改造設(shè)計思路，為提高結(jié)構(gòu)抗震性能，原有框架結(jié)構(gòu)體系轉(zhuǎn)變?yōu)榭蚣?剪力墻結(jié)構(gòu)體系，原樁基礎(chǔ)改造成樁-箱基礎(chǔ)，并通過結(jié)構(gòu)托換、消能減震等技術(shù)的應(yīng)用確保建筑安全及改造施工不影響商場營業(yè)，項目的成功運營為商業(yè)綜合體的升級改造提供了參考。

Abstract:Zhengjia Grandview Aquarium is a rarely special modification project, which conducts the construction of an aquarium inside an operating commercial building. The aquarium has introduced additional load of 10 thousand tons into the original structure. Besides, a few of frame columns has been cut in several floors. The structural modification design has fully considered the particular architectural function of aquarium and newly added enormous loads. The core modification design idea is integral design first, then component design. For the purpose of improving structural seismic performance, the original structure system has been transformed from previous frame structure system to frames and shearing-force wall structure system. The former pile foundation has been modified to pile-box foundation. In addition, structural techniques such as structural underpinning, vibration energy dissipation ect. were used to ensure the safety of the building.Applications of these structural techniques also made sure that the normal operating of commerce were not affected during the modification construction process. The successful operating of this project can be taken as a reference for the improvement and modification project of commercial complex.
Keywords:aquarium; modification project; structural system transformation; pile-box foundation; vibration energy dissipation; column underpinning
