当不同类型的横向构架组合在同一高层结构中时,由于其自由偏移形状各不同,在水平方向上它们将通过连接板相互影响。这种水平方向的共同工作,有利于增大结构物的刚度和强度。现以一框架剪力墙结构为例加以说明。此剪力墙在水平分布荷载作用下,其自由偏移为背风面呈凹形的弯曲悬臂,最大斜率在顶部(见图1a)。相反,在同样荷载作用下,单榀刚架的自由变形为迎风面呈凹形的剪切悬臂,最大斜率在底部(见图1b),将这两者组合一起,在水平荷载作用下,由于框架和剪力
When different types of transverse frames are combined in the same high-rise structure, they will interact with each other through the connecting plates in the horizontal direction due to their different free offset shapes. This horizontal working together helps increase the stiffness and strength of the structure. A frame shear wall structure is taken as an example for illustration. This shear wall under the effect of horizontal distributed load, the free deflection of the leeward surface is a concave curved cantilever, the maximum slope at the top (see Figure 1a). On the contrary, under the same load, the free deformation of the single-frame rigid frame is a sheared cantilever with a concave shape on the windward side. The maximum slope is at the bottom (see Figure 1b). Combining the two together, under the effect of horizontal loads, Frame and shear
