一般单层工业厂房和仓库建筑结构设计中常用的变截面双坡梁和悬臂梁,在构件计算时往往需要进行构件挠度复核,在轻纺工业厂房中常用的柱顶挑牛腿的 T 形柱,结构排架分析也需要计算构件的形变常数。但目前尚缺乏这些构件的变位计算公式。为了应用方便,根据这些构件在钢筋混凝土和预应力钢筋混凝土结构方面常见的荷载形式,推算了下述几种变截面构件的变位计算公式,
The double-slope beam and cantilever beam with variable cross-sections commonly used in the design of building structures for general single-storey industrial plants and warehouses often require component re-evaluation during the calculation of the components. The T-shaped column is usually used to pick the leg of the bull’s leg in the light industrial building. Structural analysis of structural fencing also requires calculation of the deformation constants of the components. However, the displacement calculation formula of these components is still lacking. In order to facilitate the application, according to the common load forms of these components in reinforced concrete and prestressed reinforced concrete structures, the following calculation formulas for the displacement of the variable cross-section components are derived.
