在设计钢筋混凝土结构的实践中,有时遇到下部具有厚翼缘的倒T形截面梁的计算情况。当受压区界限位于翼缘中时,即(?),系指下部具有厚翼缘的倒T形横梁、非标准的钢筋混凝土装配式承重梁、一列柱下的条形基础等(图1)。在这种情况下翼缘 In the practice of designing reinforced concrete structures, the calculation of the inverted T-section beam with a thick flange at the bottom is sometimes encountered. When the pressure zone boundary is located in the flange, ie (?), it refers to the inverted T-shaped beam with a thick flange at the lower part, non-standard reinforced concrete assembled load-bearing beams, and a bar-shaped strip foundation (Fig. 1) ). In this case the flange
