由滑模、大模板等施工工艺施工的多层、高层建筑,其结构体系为由连梁和楼板联结的全剪力墙结构或框架剪力墙结构,把由门洞或窗洞分割开的剪力墙结构视为薄壁焊件,这各别的薄壁杆件和普通柱子经楼板、门上梁或窗上梁相互联结而构成一空间体系。按照B. 3.符拉索夫的弹性薄壁杆件理论,如果杆件截面的厚度t和截面的最大尺寸B_(max)相比较t/B_(max)<0.1;并且B_(max)和结构的高度H相比较B_(max)/H<0.1时,可按弹性薄壁杆件进行处理。对于高层建筑结构来说,这两个条件一般是能够满足的。当按这一模型进行结构内力分析时,由于也考虑了垂直位移的协调,从而这一空间分析方法所得计算结果要更合理些。
The multi-storey and high-rise buildings constructed by the construction techniques such as sliding mode and large formwork, whose structural system is a full-shear wall structure or frame shear wall structure connected by a coupling beam and a floor, and shear force separated by a door hole or a window hole. The wall structure is considered as a thin-walled weldment. These individual thin-walled rods and common pillars are connected to each other via a floor slab, a door upper beam or a window beam to form a space system. According to B. 3. Vlasov’s theory of elastic thin-walled members, if the thickness t of the cross-section of the bar is compared with the maximum size B_(max) of the cross-section, t/B_(max)<0.1; and B_(max) and When the height H of the structure is compared with B_(max)/H<0.1, it can be treated as an elastic thin-walled bar. For high-rise building structures, these two conditions are generally satisfactory. When the structural internal force analysis is performed according to this model, since the coordination of vertical displacement is also considered, the calculation results obtained by this spatial analysis method are more reasonable.
