Test on shear behavior of reinforced concrete beams filled with demolished concrete lumps
摘要
Abstract
In order to investigate the shear behavior of reinforced concrete (RC ) beams filled with demolished concrete lumps (DCLs) , 12 RC beams filled with DCLs and two conventional RC beams were tested to reveal the shear strengths and deformations of the specimens.Based on the test data, a formula is proposed to predict the shear strength of RC beam filled with DCLs.Test results show that; (a) the initial stiffness of RC beam filled with DCLs is almost the same as that of conventional RC beam; ( b) the cracking load and shear strength of RC beam filled with DCLs without stirrups are less than those of conventional RC beam without stirrups, but the cracking load and shear strength of RC beam filled with DCLs with stirrups are almost the same as those of conventional RC beam with stirrups; and ( c) the shear strength calculated using current design code has a similar safety margin for conventional RC beam with stirrups and RC beam filled with DCLs with stirrups.关键词
