Numerical Investigation on the Effect of Partially-Inclined Reinforcement on the In-Plane Behavior of Shear-wall

Abstract

A shear wall is a structural component commonly used in buildings to resist lateral loads such as
wind and seismic forces. They are vertical elements typically made of reinforced concrete,
masonry, or steel. The effectiveness of shear walls in resisting lateral loads depends on various
factors including their size, material properties, connection details, and the overall structural
design of the building. An innovative idea of a concrete shear wall with partial diagonal
reinforcement was introduced in this paper. All specimens were modelled and analyzed with the
finite element software ABAQUS. The investigation was carried out to investigate the global
behaviour of the shear wall in terms of lateral load and story drift response, yielding of
reinforcement, and plastic concrete strain by varying the angles of inclined reinforcement from
45° to 65°. The research shows that the seismic performance of the shear wall in particular its
resistance to sliding shear, was improved through this layout of the inclined reinforcement.
Compared to the other shear walls, the shear wall with 60° partial rebars has a maximum lateral
strength.
