南沙某仓库,总建筑面积约6.0万m2,两层框架结构。由于结构总高度受物流仓库货物限制。总高度超过24m高度造成消防建筑等级及结构抗震等级的级别提高。从经济角度考虑。业主希望总高度不超过24m而且要充分利用室内净空,尽量减少结构层高度,所以在结构方案选择上,选择当前兴起的空心楼板形式,在空心楼板设计上,涉及到各种计算模型的具体的结构布置形式,而且结构柱跨度达10m结构活荷载重达35k N/m2,均与常规的结构设计有很大不同。本文分析了密肋梁模型及大板模型,得出对于该工程目前大板模型的经济性要优于密肋梁模型。
Nansha a warehouse, with a total construction area of about 60,000 m2, two-story frame structure. Due to the total height of the structure of the logistics warehouse goods restrictions. The total height of more than 24m height caused by the level of fire building rating and structural level of anti-seismic level. From an economic point of view. Owners hope that the total height of not more than 24m and make full use of indoor clearance to minimize the height of the structural layer, so the choice of structural options, the rise of hollow floor form, in the hollow floor design, involving a variety of computing models specific Structural layout, and structural column span of 10m live load weight of 35k N / m2, both with conventional structural design is very different. In this paper, the beam girder model and the slab model are analyzed, and the economy of the present slab model is better than the girder beam model.
