摘　　要：本文进行了９根高强钢筋高强混盛大梁和２根普通钢筋高强混凝土梁的试验研究，探讨了其受力变形特点。经分析推导，提出了高强钢筋高强混凝土梁的抗裂弯矩和裂缝宽度计算公式，以及刚度、挠度计算方法，其计算结果与试验结果符合较好。Nine high-strength concrete beams with high-strength rebars and two with ordinary rebars were tested and studied . In which, the deformation characteristics of beams were investigated . Through analyses and derivations, the calculation formulas for crack resistant bending moment and crack width as well as the calculation methods of rigidity and deflection have been presented . The results calculated by the proposed formulas are in good agreement with those of the tests.
