使用一个简单平面框架说明施工加载的两个概念：1）施工过程中重力荷载在竖向构件变形协调下对各构件的内力影响；2）采用施工过程加载模拟和一次性加载的差别及分析，同时引述了其他一些施工加载的问题，以期能引起对施工加载计算的重视和对计算方法的思考。%The paper adopts the simple plane framework to indicate two concepts, including the gravity loading' s internal stress influence on all components with the deforming coordination of the vertical components in the construction and the adoption of the loading simulation of the con- struction process and the difference and analysis of the one-trial loading, and indicates some problems in other construction loading, so as to a- muse enough emphasis for the loading calculation in the construction and the consideration for the calculation methods.
