Abstract
In order to explore the role of high-ductile concrete in improving the seismic performance of shear wall,the modified active powder concrete is prepared,in which polypropylene fiber and steel fiber are added.Three sets of shear wall specimens were made,and the third set of specimens were partially replaced and reinforced by high-tensile concrete,and the other two sets were used as control groups.Apply vertical load and horizontal load to the specimen,and observe the damage form,displacement and reinforcement strain.After comparison,the bearing capacity and deformation and energy dissipation effect of the reinforced specimen are stronger than that of the control group,indicating that the reinforced shear wall has better seismic performance.关键词
