Response of R.C. Frames With Partial Infill Subjected To Lateral In-Plane Loading


Abstract eng:
Infill walls in reinforced concrete framed buildings are often constructed up to a limited height of columns to provide more lighting and ventilation especially in the corridor of public buildings like schools, hospitals, etc. These partial infill walls have an important role in lateral load-transfer mechanism in building frames. Performance of RC framed buildings in past earthquakes clearly illustrates that the columns of partial infilled frames fail due to short-column and captive-column effects. In the present study, finite element analysis of partial infilled frame with different height of infill are carried out in open source code OpenSees. In the analysis, nonlinear behaviour of frame elements is modelled while infills are assumed to be linear elastic. Separation and sliding at the frame-infill interfaces are also modelled. The lateral stiffness of partial infilled frame considering perfect contact at the interface is compared with the lateral stiffness of the same frame considering separation and sliding. It is concluded that the separation and sliding at frame-infill interfaces has an important role in reducing stiffness of infilled frame.
