钢纤维再生混凝土压-剪受力分析
Compression-shear Force Analysis of Steel Fiber Recycled Concrete
摘要
Abstract
To study the compression-shear composite axial state performance of steel fiber recycled concrete,different volume rates of steel fi-bers(0,1%,2%and 3%)were added,and the compression-shear mechanical properties of steel fiber normal concrete with the same condi-tions were analyzed in comparison.By selecting the axial compressive loads of 0 and 10 MPa,the damage patterns and displacement-load curves were obtained under different working conditions.The results show that:the presence of steel fibers can increase the shear strength val-ue of recycled concrete and ordinary concrete,and the integrity of the specimen can be maintained after shear damage;the presence of axial pressure specimens have obvious friction traces on the shear damage surface,but it effectively improves the shear strength value.According to the mathematical regression analysis,the linear relationship between the peak load and the amount of steel fiber was obtained.关键词
