中文摘要: 为了处理汶川地震产生的大量建筑垃圾,研究以再生混凝土梁为对象,通过现行规范的理论分析建立了以再生骨料取代率为参数的再生混凝土梁正截面受弯承载力计算公式,并通过有限元分析得到了再生混凝土梁受弯全过程的M-φ关系曲线。结果表明,理论计算结果与再生混凝土梁的试验数据符合较好,方差分析表明理论分析和有限元分析两种算法本身都是适用的,为再生混凝土梁设计提供了有价值的参考依据。
中文关键词: 再生混凝土  受弯承载力  取代率
Abstract:In order to treat the large waste concrecte caused by the Wenchuan Earthquake,the RC(recycled concrete) beam flexural capacity calculation formula with the recycled aggregate replacement rate was founded according to the Code for design of concrete structures. The M-φ relation curves of the RC beams were calculated by the analyses of finite element method. The results showed that the results of calculation accorded well with the results of recycled concrete beam experiments all over the world. Variance Analysis proved that these two methods are both applicable. The research supplied much valuable references for the design of RC beam.
