The effect of in-plane damage on the out-of-plane response of reinforced and thermally insulated masonry elements and infills was examined in this dissertation experimentally and analytically. Structural reinforcement was realized through the use of textile reinforced mortar while regular expanded polystyrene was used for thermal in-sulation. Various specimen configurations were tested both in- and out-of-plane sequentially within a strong frame using hydraulic actuators to impose the respective loads. Experimental results have shown that the TRM-based strengthening scheme can improve the out-of-plane response of masonry infills both in terms of strength and stiffness, especially in the case of pre-damaged walls. The addition of insulation arranged in a "sandwich" configuration resulted in a slight out-of-plane improvement, but was not as effective in the case of pre-damaged specimens. Last but not least, numerical and analytical models are proposed which can predict the out-of-plane behavior of masonry elements and infills while also accounting for the existence of reinforcement and prior damage.
