摘要
根据带支撑体系框架结构的受力特点，对施工阶段框架内力进行探讨。通过大量结构的电算，表明带支撑框架结构的支撑间距、面积和材料的变化均会影响上层梁内力的变化，但变化的幅度并不大，在5％～10％左右。带支撑结构本身刚度大，可视为一独立的结构进行计算分析。最不利支撑受力体系为梁柱线刚度比较小的双跨单层支撑体系。
According to mechanics characteristic of frame structure with brace system, internal force of frame beam during construction phase is discussed. By calculated plenty of Multi-story Concrete Frames（ MCF）, brace parameters such as the spans, areas, floors and material selected of the brace system should be noted. Variation of internal force will be range about 5% - 10%. As braced system has rigidity, it can be separated from the whole structure. It is shown that single floor, double spans, the smaller ratio of beam and column may be the unfavorable factors.
