Masonry Infill RC Frames with Openings: Review of In-plane Lateral Load Behaviour and Modeling Approaches

Abstract: Un-reinforced masonry walls are commonly used as infills in reinforced concrete (RC) buildings. These buildings have high in-plane stiffness and strength, and therefore, the lateral load behaviour of such RC frames is different than that of the frames without infill walls. Openings in walls significantly reduce the lateral strength and stiffness of RC frames, and alter their failure modes. Past researchers have tried to find out experimentally and analytically the influence of several parameters, like opening … Show more

“…A comparison was made in terms of initial stiffness and lateral strength between both models ( Table X). It is considered that these results validate the ability of Equation (16) in predicting the initial stiffness and lateral strength of multi-storey infilled frames with any distribution of openings in the infills. It is considered that these results validate the ability of Equation (16) in predicting the initial stiffness and lateral strength of multi-storey infilled frames with any distribution of openings in the infills.…”

“…Once the stiffness of the solid infill and bare frame are calculated, that is, K fill and K bare , respectively, these parameters can be replaced in Equation (16) for the calculation of the width of the equivalent diagonal strut for each one-bay one-storey frame inside the multi-storey structure.

“…This phenomenon has seldom been reported in the literature because most of the quasi-static reverse cyclic tests are displacement controlled with symmetric displacement cycles. Nevertheless, significant asymmetric lateral-load transfer mechanisms of infilled frames with openings have been reported [34,35].…”

“…In such cases, element birth and death techniques could be used to deactivate or reactivate selected elements, respectively [9]. To achieve the "element death" effect, it does not mean that the "killed" elements are actually removed.…”
