Summary Eight half‐scale brick masonry walls were tested to study two important aspects of confined masonry (CM) walls related to its seismic behavior under in‐plane and out‐of‐plane loads. Four solid wall specimens tested to investigate the role of type of interface between the masonry and tie‐columns, such as toothing varying from none to every course. The other four specimens with openings were tested to study the effectiveness of various strengthening options around opening to mitigate their negative influence. In the set of four walls, one wall was infilled frame while the other three were CM walls of different configurations. The experimental results were further used to determine the accuracy of various existing models in predicting the in‐plane response quantities of CM walls. Confined masonry walls maintained structural integrity even when severely damaged and performed much better than infill frames. No significant effect of toothing details was noticed although toothing at every brick course was preferred for better post‐peak response. For perforated walls, provision of vertical elements along with continuous horizontal bands around openings was more effective in improving the overall response. Several empirical and semi‐empirical equations are available to estimate the lateral strength and stiffness of CM walls, but those including the contribution of longitudinal reinforcement in tie‐columns provided better predictions. The available equations along with reduction factors proposed for infills could not provide good estimates of strength and stiffness for perforated CM walls. However, recently proposed relations correlating strength/stiffness with the degree of confinement provided reasonable predictions for all wall specimens. Copyright © 2016 John Wiley & Sons, Ltd.

“…From the available published experimental [134,31,189,70,87,[92][93][94]138,139,17,158,103,140,95,100,175,132,71] and numerical [135,128,80,86,11,16,186,67,164,64,69,60,161] [110,17,18,42,37,68,172,76,144,176,24,96] data, it can be observed that masonry infill walls (referred to also as infill walls in this paper) can have a significant effect on the structural performance of RC frames under seismic actions. This can result in a localized or global increase of strength and stiffness depending on the extent and the position of the infill walls within the frame.…”

In recent years, the interest in the out-of-plane response of infills has been growing due to the need of limiting damage to these elements, commonly considered as non structural. Different experimental tests and theoretical studies have been carried out on this subject. They highlighted that the slenderness and the boundary conditions of the panel, the mechanical characteristics of the masonry, the stiffness of the surrounding frame elements and the presence of cracks due to prior in-plane damage noticeably affect the out-of-plane carrying capacity of infill walls. In this paper, a review and a comparison of analytical models developed for the assessment of the out-of-plane response of masonry infills is presented. The suitability of selected models to predict the out-of-plane capacity is investigated by means of some experimental results available in the literature. It is concluded that, even though the considered models take into account the main parameters involved (slenderness of the panel, masonry compressive strength, etc.), they are not always able to adequately predict the actual resistance.
