摘要
为探究高延性混凝土在提升剪力墙抗震性能方面的作用,文中研究制备了改性活性粉末混凝土,其中添加了聚丙烯纤维和钢纤维.制作三组剪力墙试件,利用高延性混凝土对第三组试件进行局部置换加固,另外两组作为对照组.通过向试件施加垂直载荷与水平载荷模拟地震作用,观察其破坏形态、位移量、钢筋应变.经对比可知,加固试件的承载能力、变形消能效果均强于对照组,说明加固后的剪力墙具有更好的抗震性能.
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.
