本结构是在不拆除原建筑物的情况,采用框架结构加层,将原建筑物从35层,加高到8～13层,不再占用建筑用地。原建筑物地基可以是岩层或土层,所加层重量不压在原建筑物上,但使新、旧结构一体化,表面上看不出加层迹象,所需费用比拆除原建筑物节约30～60％左右。本结构还使用了建筑物抗震减震装置。采用本结构必须索取该技术的关键措施,否则盲目利用,将会留下严重后患。 The structure is without demolition of the original building situation, the use of frame structure plus layer, the original building from the 35th floor, raised to 8 to 13 layers, no longer occupy the construction site. The foundation of the original building can be a rock or soil layer, and the weight of the added layer does not rest on the original building. However, if the new and old structures are integrated, no signs of additional layer can be seen on the surface and the cost can be saved by 30% ~ 60% or so. The structure also uses a building seismic damping device. The use of this structure must obtain the key measures of the technology, or blind use, will leave a serious risk.
