Analysis of Composite Behavior of Masonry Wall and Supporting Beam

Abstract

Composite behavior of brick masonry wall and supporting beam is outlined through this topic. Masonry in filled reinforced concrete construction is most common in urban and rural areas. The composite behavior of masonry and the supporting beam is neglected in the modern structural design. In the present study, finite element analysis is used for analysis of composite action of wall and supporting beam. Materials are modeled using Macro modeling. The properties required for material modeling has been taken from the literature. The composite action of masonry wall with supporting beam is studied by various parameters such as height to span ratio, size and position of opening in the wall, elastic properties of masonry and beam. Vertical stress and shear stress variation along the span are plotted at the interface between wall and supporting beam. The bending moment, axial force in the beam and vertical compressive stress in the wall are determined by varying various parameters.
