摘　　要：梁式转换结构具有传力清晰明确、结构形式较为简单等优点,但存在许多弊端,如转换梁刚度过大易形成“弱柱强梁”的不利构造以及梁自重较大造成转换层质量过大等缺点。而出现的斜柱转换结构在一定程度上弥补了梁式转换结构的缺点与不足,斜柱的设置提升了转换结构转换梁抗剪承载力,有效减少了转换梁的截面高度。对此建立了斜柱式和梁式转换结构的两组受力模型,采用有限元软件对荷载作用进行对比分析,总结斜柱转换结构的受力特点和梁式转换结构的优缺点,通过试验表明了再有效降低转换梁截面的同事,由于斜柱对转换梁的支撑作用以及斜柱、转换梁、框架柱的稳定三角体系,斜柱转换结构比梁式转换结构的抵抗竖向荷载和水平变形能力更优,为高层建筑中应用斜柱转换结构提供参考。The beam type conversion structure,which has the advantages of clear force transmission and simple structure,but there are many disadvantages,such as the conversion beam stiffness is too large,easy to form the unfavorable structure of weak column strong beam and the beam dead weight caused by the large quality of the conversion layer and other shortcomings.The inclined column conversion structure makes up for the shortcomings and deficiencies of the beam conversion structure to a certain extent.The setting of the inclined column improves the shear capacity of the conversion beam of the conversion structure and effectively reduces the section height of the conversion beam.In this paper,two groups of force models of inclined column transfer structure and beam transfer structure are established.The finite element software is used to compare and analyze the load action,and the force characteristics of inclined column transfer structure and the advantages and disadvantages of beam transfer structure are summarized.The test shows that the colleagues who can effectively reduce the section of transfer beam,because of the supporting effect of inclined column on transfer beam and the stable triangular system of inclined column,transfer beam and frame column,the inclined column transfer structure has better resistance to vertical load and horizontal deformation than beam transfer structure,which provides reference for the application of inclined column transfer structure in high-rise buildings.
