| 摘 要： | 目前对活性粉末混凝土梁的正截面抗裂性能尚缺乏系统的研究,钢纤维加入后对受拉区混凝土塑性变形的影响也未做较为深入的探讨。为此,在试验研究的基础上建立了活性粉末混凝土梁的正截面抗裂计算模型,结合试验数据和有限元分析结果,提出活性粉末混凝土梁正截面抗裂计算公式。

| Abstract: | The crack-resistant capacity performance of RPC beam hadn't been researched systematically at present,and the effects of the steel fiber added on the plastic deformation of the RPC tension region hadn't been studied deeply.Based on the theoretical and finite element analysis,the model of the crack-resistant capacity of reactive powder concrete beams is set up,and the calculating formula are presented.The results from the method coincide well with those from the tests. |
