【摘要】 预应力混凝土板柱结构在大开间的多层及高层建筑中得到了广泛的应用，其设计方法有直接设计法、等代框架法、塑性分析法和有限元法等多种方法。其中等代框架法为国内外规范推荐和工程界广泛使用的方法。等代框架法对规则板柱结构的分析比较接近真实情况，对板带宽度变化的板柱结构则需作近似或改用有限元法来计算。本文对板带宽度变化的板柱结构推导了变截面直杆单元的单元刚度矩阵和等效结点荷载列阵，避免了在结构分析时所作的近似，也扩大了等代框架法的计算范围，使工程技术人员免于使用占用机时、难于掌握的有限元分析法。在本文中，还给出了预应力混凝土板柱结构用等代框架法进行分析和设计的步骤和框图，阐述了柱帽、托板、边梁、扁梁对结构内力分析的影响。更多还原

【Abstract】 Prestressed concrete slab-column structure has been widely used in long-span and multistory building. There are four commonly used analysis methods for slab-column structure, which are direct design method, equivalent frame method, plasticity method and finite element method. The equivalent frame method is recommended at home and abroad, and it is also the most common method in engineering circles. The analysis result on prestressed concrete slab-column structure in regular column layout is closed to that of actual situation. For slab-column structure of variable slab width, approximation is needed or is replaced by FEM. This paper presents the element stiffness matrix and equivalent node force of the variable cross-section bar. So the approximation in structural analysis is avoided, and the calculation capacity of equivalent frame method is also developed. This helped the engineers avoid the FEM, which consume much time and is difficult to master. In this paper, the steps and frame of analysis and design is presented and the influence of column capital, drop panel, edge beam and flat beam on structural analysis is introduced.更多还原
