Abstract

Infill panels are usually used in structures; therefore, it is very important to study their behaviour and their influence on bare frames. Several models had been proposed to understand the effect of the infill panels on structure. The aim of this work is to identify the effect of the presence of infill panels on bare frames. The diagonal stiffness and shear compression failure of the structure, the nonlinear behaviour of the infilled frame under axial loading and the relation between the strength, ductility and stress-strain of different previous experiments will be presented. Experimental research on the interaction between the steel frames and infill panels has been done to determine the behaviour of steel frames with different types of infill walls. Many frames with composite panels subjected to cyclic-loading were realized to determine the damping ratio, the static and dynamic response, strength and stiffness degradation of infill elements. The objective of this paper is to represent and analyze the hysteretic behaviour, failure modes, and the variation of different parameters of the infilled bare frame like stiffness, strength, ductility and loading displacement curves.
