摘　　要：再生混凝土正截面开裂弯矩在土建工程中并不少见,混凝土的极限拉应变和梁的抗裂性能有着直接性的关系。然而,在再生混凝土的发展中并没有其受拉应力-应变全曲线报告。为此,如何使用再生混凝土拉伸应力应变关系,在整个土建工程中显得非常重要。通过分析再生混凝土的发展状况,再生混凝土梁开裂弯矩的影响因素和再生混凝土的结构的性能,分析了再生混凝土梁正截面开裂弯矩理论计算模式,论证出再生混凝土梁正截面开裂弯矩计算公式具有较好的适用性,在结尾分析了再生混凝土发展趋势。Recycled concrete of normal section cracking moment is not uncommon in civil engineering, the ultimate tensile strain of concrete and the beams crack resistance has a direct relationship.However, in the development of recycled concrete and not by the tensile stress-strain curve of the report.To this end, how to use recycled concrete tensile stress-strain relationship is yery important in the entire civil works.By analyzing the state of development of the recycled concrete, recycled concrete beams cracking moment of impact factors and recycled concrete structure of the performance analysis of the beams cracking recycled concrete beams cracking moment theory computing model, demonstrated the regeneration of coagulation moment formula has better applicability of recycled concrete development trends at the end.
