Influence of Masonry Walls on Unintended Torsional Response of Framed-Masonry Building
Earthquakes have shown that buildings that are regular in plan and elevation have more favorable behavior than irregular buildings. This is in part because torsional effects in irregular buildings can amplify demands. But sources of irregularity are not always the result of structural design decisions. Masonry walls are often used in reinforced concrete buildings for architectural purposes, but their presence and the locations of openings in them can introduce stiffness irregularities that affect structural response. The aim of this paper is to show, through dynamic earthquake-simulation tests, the torsional response of a three-story reinforced concrete frame-masonry building. Two series of tests were considered: in the first series, the structure had unreinforced clay block masonry walls ; in the second, the masonry walls in the first and the second stories were replaced by solid brick walls and vertical reinforced confining elements were added around openings. In both series, the structure was subjected to sequences of ten ground motions of increasing intensity from 0.05 up to 1.2 g along a single axis. In addition to in-plane drift, out of-plane drift at the roof also was observed, suggesting rotational response. Conclusions are given in the form of torsional stiffness variation with respect to ground motion intensity i.e. structural damage increase.
