Analysis of the mechanical behavior of the recycled concrete-filled double skin shear walls with ribbed stiffener and opening
摘要
Abstract
In order to study the mechanical behavior of the recycled concrete-filled double skin shear walls with ribbed stiffener and opening, numerical simulation for the shear walls, the accuracy of which was verified, was conducted based on finite element software ABAQUS. The stress failure process of the walls was discussed, and the effects of opening rate, replacement ratio of waste concrete, shape of the hole, strength of the steel plate and axial compression ratio on the mechanical property were taken into account under unilateral horizontal load. The results indicate that the influence of opening rate and replacement rate of waste concrete on the mechanical property of the walls was significant. The stiffness and bearing capacity was reduced, but the deformation capacity was improved due to increased peak displacement. The shape of the hole has obvious influence on mechanical property of the walls, and the mechanical property of the walls with wide flat hole was poor. The bearing capacity and deformation capacity of the walls were enhanced by improving strength of the steel plate. With the increase of axial compression ratio, the bearing capacity of walls was improved, but the deformation capacity was decreased.关键词
