Characterization of the Out-Of-Plane Behaviour of Full-Scale Masonry Infill Walls With and Without Previous In-Plane Damage: Experimental Study


Abstract eng:
The seismic performance of the infill masonry (IM) walls is characterized by the interaction with the surrounding reinforced concrete (RC) frames, which can result in different failure modes depending on their in-plane and out-of-plane behaviour. It is known that the out-of-plane capacity of the IM walls is conditioned by the existence of previous in-plane damage that could decrease significantly their strength and stiffness, as well as the reduced support-width on RC beams and/or slabs adopted to minimize thermal bridges effect, or the absence of connection between the infill panel and the surrounding RC frame can result in a poor out-of-plane performance. However, in the literature the number of experimental studies regarding to IM walls subjected to out-of-plane loadings, combined or not with in-plane damage is reduced. For this an experimental testing campaign of full scale IM walls was started at the Laboratory of Earthquake and Structural Engineering – LESE by performing three experimental (cyclic and monotonic) out-of-plane tests with and without previous in-plane damage. The dimensions adopted for the specimens are representative of those existing in a large portion of the Portuguese building stock according to recent studies. The experimental campaign and test setup will be described as well as the experimental tests’ results will be presented and discussed in the manuscript in terms of hysteretic force-displacement curves and damage evolution.
