[摘要]通过简化的二维模型,对不同荷载作用下、不同倾斜方式的斜柱对楼面水平构件的内力影响进行分析,指出随斜柱倾斜方式的不同,斜柱转折层与之相连的水平构件内力方向完全不同,该力对核心筒支承部位局部区域产生较大作用,且在水平荷载作用下外折角层的斜柱会对该层核心筒墙体产生附加水平剪力。结合工程实例,针对转折层构件受力特征对如何可靠传递由斜柱引起的水平力提出设计建议。转折层中与斜柱相连的水平构件的承载力应予以加强,并宜保留一定的冗余度。

Abstract:The simplified two-dimensional model was used to analyze the influence of inclined columns on the internal force of horizontal members of the floor under different loads and inclined modes. It was pointed out that the internal force direction of the horizontal members connected with the inclined column transition layer is totally different when the inclined modes of the inclined columns were different. The forces have a great effect on the local area of the supporting part of the corewall, and the inclined columns of the outer folding angle layer produce additional horizontal shear force to the corewall of the layer under the action of horizontal loads. Combined with the engineering examples, the design suggestions were proposed on how to reliably transfer the horizontal force caused by the inclined column according to the mechanical characteristics of the transition layer members. The bearing capacity of the horizontal members connected with the inclined columns in the transition layer should be strengthened and a certain degree of redundancy should be reserved.
Keywords:inclined column; transition layer; inner folding angle; outer folding angle
