［摘要］通過簡化的二維模型，對不同荷載作用下、不同傾斜方式的斜柱對樓面水平構(gòu)件的內(nèi)力影響進行分析，指出隨斜柱傾斜方式的不同，斜柱轉(zhuǎn)折層與之相連的水平構(gòu)件內(nèi)力方向完全不同，該力對核心筒支承部位局部區(qū)域產(chǎn)生較大作用，且在水平荷載作用下外折角層的斜柱會對該層核心筒墻體產(chǎn)生附加水平剪力。結(jié)合工程實例，針對轉(zhuǎn)折層構(gòu)件受力特征對如何可靠傳遞由斜柱引起的水平力提出設(shè)計建議。轉(zhuǎn)折層中與斜柱相連的水平構(gòu)件的承載力應(yīng)予以加強，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
