混凝土矩形截面受弯纵向受拉钢筋配筋计算
Various limiting values available in some countries design codes of concrete structures for minimal ratio of longitudinal tensile reinforcement in non-seismic reinforced concrete beams are studied.
通过对各有关国家混凝土结构设计规范中非抗震梁类构件受拉钢筋最小配筋率取值规定的对比分析,展示了有关这类最小配筋率取值的国际总体情况,指明了各国规范中存在抗震与非抗震情况取值相同和抗震与非抗震情况取值高低不同的两种取值体系,和各国正在向有模型的取值方案过渡的总体趋势;并在这一认识的基础上,为我国国家标准《混凝土结构设计规范》(GBJ10-89)提出了修订这类最小配筋率取值的建议。
