Analyzing the Effect of Infill Walls on a RC Structure
Abstract
In reinforced concrete
buildings, the openings between frames are generally filled by using infill
material and by plastering the sides. This application is called infill wall,
and it is widely acknowledged as a non-structural element. Therefore, infill
walls are often designed assuming that they do not have any effect on the
structure other than their weight. However, several experimental and
theoretical studies have documented that infill walls, in fact, affect the
behavior of a structure under vertical and horizontal loads along with its
dynamic characteristics such as its stiffness, period and damping. This study
aims to investigate the effect of infill walls on the earthquake performance of
a selected building. The structure with and without infill walls has been
modelled in SAP2000 structural analysis software and the pushover analysis has
been carried out. The infill walls have been modelled as commonly used diagonal
bracing without any tensile capacity, which are compatible to their actual
behavior. As a result of the comparison of the analyses, infill walls have been
found to increase the earthquake performance of the structure, limit the
displacement and contribute to the base shear force.
