Bracing walls are important buildings elements and have attracted the attention of many researchers in recent years. Thus, there is substantial information available about their behaviour. Most previous studies were on walls without openings and of single-floor height. However, in tall buildings, it is typical to have bracing walls with openings repeated over multiple stories. Considering coupled walls is more significant for tall buildings since a coupling beam over a door opening or masonry infill above and below a window opening will significantly alter their behaviour, stiffness and load capacity. A literature review indicated the need for tests on multi-story bracing walls with openings to determine the actual mechanism of rupture, maximum lateral load, and post-cracking stiffness taking into account the effects of openings, cracking, shear distortions, and axial forces. Here, we present the preliminary results of the first two tests in an extensive testing program of half-scale three-story reinforced masonry walls with door and window openings. Results from walls coupled by masonry or reinforced concrete beams are discussed in this paper. (AU) | |
