| 摘 要： | 首先建立了钢筋钢纤维混凝土梁曲率沿梁长的分布曲线模型,然后结合结构力学理论,推导了钢筋混凝土梁和钢纤维增强钢筋混凝土梁变形的理论计算公式,并结合试验结果,提出了适合于钢筋混凝土梁和钢纤维增强钢筋混凝土梁,并研究了钢纤维对钢筋混凝土梁等效塑性区长度的影响.研究表明,钢纤维增大了等效塑性区长度,使构件塑性区的塑性变形能力得到了改善,提出的等效塑性区长度的统一计算公式可用于钢筋混凝土构件和钢纤维增强钢筋混凝土构件等效塑性区长度的计算,计算结果与试验结果比较吻合.

| Abstract: | Based on the distributing curve model of curvature and the theory of structural mechanics,this paper derives formula of computing the deformations of reinforced concrete beams and steel fiber reinforced concrete beams,puts forward uniform formula of equivalent plastic area length fitted to reinforced concrete beams and steel fiber reinforced concrete beams by combining with test data,studies the effect of steel fibers on equicalent plastic area leagth of reinforced concrete beam.These results show that steel fibers increase the equivalent plastic area length,improve the ability of the plastic deforming of plastic area. |
