ABSTRACT
This paper presents an analytical simulation approach which considers the critical modelling aspects in reinforced concrete (RC) buildings with unreinforced masonry (URM) infill walls, e.g. in-plane/out-of-plane interaction, explicit account of infill failure through element removal and consideration of shear damage of the columns due to frame/wall interactions. A commonly configured and code-designed five story RC frame with URM infill walls is analysed under the effect of bi-directional ground motions. The analysis results clearly demonstrate the effect of URM infill walls on the response of RC frames and the necessity for proper modelling in order to represent these effects realistically, even for the cases of code-designed frames.
