【摘要】 通过分析大量试验数据,分析了影响再生混凝土梁抗剪承载力的因素,并结合规范GB 50010—2002拟合出了再生混凝土梁抗剪承载力公式。再生混凝土梁抗剪承载力比普通混凝土梁低,并随着再生混凝土骨料取代率的增大而降低,工程设计中要控制取代率。更多还原

【Abstract】 Through the analysis of test data,he influence of recycled concrete beam shear bearing capacity factors were given.Combined with GB50010-2002,shear bearing capacity formula of recycled concrete beam was fitted out.Recycled concrete beam shear strength was lower than ordinary concrete beam,and with the recycled concrete aggregate replacement ratio increased.In engineering design,the recycled concrete aggregate replacement ratio should be controlled.更多还原
