Experimental Study on Seismic Failure Modes of Confined Masonry Structures with Different Enhancements

Abstract

In this study, confined masonry specimens with regular arranged openings are tested in order to study the influence of different enhancements of the columns on seismic failure modes. In particular, five brick masonry walls and three half-scale two-storey masonry structures are tested under quasi-static loads. The experimental results show that increasing column ratio improves the seismic behavior of the wall specimens to some extent, but an excessive reinforcement ratio of the columns decreases the ductility. The global failure mode of the two-storey masonry structures is modified by inserting iron wires in the mortar bed joints, improving the structural collapse resistant capacity effectively.

Irregularity of the Distribution of Masonry Infill Panels and Its Effect on the Seismic Collapse of Reinforced Concrete Buildings

“…Most of the models used to numerically simulate the cyclical response of confined masonry buildings have been validated using laboratory tests in which the specimens were subjected to gravity loads and lateral loads in the masonry plane [1,[24][25][26].…”
