通过集中荷载作用下的6根钢筋混凝土梁的受剪试验,研究废玻璃粉掺量和混凝土强度对钢筋混凝土梁的受力与变形性能的影响.试验结果表明:废玻璃粉钢筋混凝土梁的受剪破坏形态相似于普通钢筋混凝土梁;废玻璃粉钢筋混凝土梁的开裂荷载比普通钢筋混凝土梁要低;在废玻璃粉掺量相同的情况下,试件的承载力随着混凝土强度的增大而逐渐增大,跨中挠度逐渐减小;在相同混凝土强度设计等级的情况下,试件的承载力随着废玻璃粉掺量的增加而逐渐下降,跨中挠度逐渐增大.废玻璃粉钢筋混凝土梁的受剪承载力具有与普通钢筋混凝土梁相接近的计算安全性,其计算公式可以采用普通钢筋混凝土梁的受剪承载力公式.

Through the shear test of six reinforced concrete beams underconcentrated load, it studies the influenceon the stress state and deformation of the reinforced concrete beam exerted by the mixed waste-glass-powder quantityand concrete strength.Experimental results show that the shear failure mode of the waste-glass-powder reinforced concrete beams is similar to that of ordinary reinforced concrete beams.The cracking load of waste-glass-powder reinforced concrete beams is lower than the ordinary reinforced concrete beams.Under the condition mixing...
