Abstract
In order to further study the seismic performance of recoverable functional prefabricated high-strength recycled concrete shear walls,a constant vertical axial loading test was carried out by preparing 4 groups of specimens,and the effects of different factors on the horizontal force,characteristic stiffness and equivalent viscous damping coefficient of the recycled concrete shear walls were systematically analyzed.The results show that the higher the strength grade of concrete,the greater the horizontal force,equivalent viscous damping coefficient and characteristic stiffness.The smaller the replacement rate of regenerated coarse aggregate,the larger the horizontal force,the larger the characteristic stiffness,and the smaller the equivalent viscous damping coefficient.The greater the steel fiber content,the greater the equivalent viscous damping coefficient.It is suggested that the recycled concrete shear wall with the strength grade of concrete C60,the replacement rate of recycled coarse aggregate of 50%and the volume rate of steel fiber of 1%should be adopted for optimization.关键词
