［摘要］采用风洞试验方法获得了呈平面S形布置的高层建筑的整体体型系数，探讨由于伸缩缝的设置使得在设计中变成两栋独立建筑后，两幢塔楼的整体体型系数，并分析了其分布规律，供设计参考。研究发现，整体体型系数沿高度递减；S型高层建筑风荷载作用在短轴方向时，其整体体型系数较大,须引起设计的重视；考虑伸缩缝后，每个塔楼在两栋塔楼邻接面的风压为0，即相当于只受三个面的风荷载。

Abstract: The total body shape coefficients of an S-type high-rise building are obtained using wind tunnel test. The setting of temperature joint in the middle part of the building results in two independent buildings. The total body type coefficients and distribution of body type coefficients of the two buildings are investigated, which could be a useful reference for the wind-resistant design of buildings with similar shape. Results from this study show that the total body type coefficients of the building decrease as the height on the building increase. The total body type coefficients on the short axis of the S-type high-rise building are significant, which should be paid much more attention in the design. When considering the effect of the temperature joint, the wind pressures on the neighboring face of the two independent buildings are zero, indicating that only three faces of the independent buildings are under wind action.

Keywords: wind tunnel test; body shape coefficient; S-type high-rise building; resultant wind force
