摘要
基于现有试验研究资料，进一步分析了钢筋混凝土和预应力混凝土叠合梁的正截面受力性能，提出了其正截面超配筋界限判别和正截面承载力计算方法，与普通钢筋混凝土和预应力混凝土梁相应计算形成统一理论体系。
Based on the existing experimental researching information, this paper makes a further analysis on the frontage cross-sectional mechanical properties of reinforced concrete and pre-stressed concrete composite beams, suggests the method of differentiating the over reinforcement limitation and a method for calculating its frontage cross-sectional bearing capacity. A unified theoretical system is formed concerning the ordinary RC beams and the pre-stressed concrete beams.
