Study of the seismic behavior of confined masonry buildings typical of the Totoracocha - Cuenca sector

Cuenca is a city of high seismic threat. 60% of its built heritage is made up of confined masonry buildings (MC). The seismic behavior of this typology is more complex than non-reinforced masonry, due to two problems: 1) Marco-Park interaction and 2) instability of failure modes as an effect of the openings on the walls, not well resolved by seismic engineering. In this sense, in the seismore resistant capacity project and walls of walls composed of confined masonry (XVII call-Diuc), it was proposed to solve them by implementing a wall-element wall for static non-linear analysis Pushover of walls confined with typical characteristics of the built heritage of the city. The project that proposes continuity to the aforementioned of the past call. From the validated wall-element, incorporating the floor system model, both a mass model and a 3D Pushover analysis model will be established. In this way, it is proposed to study the seismic behavior of confined masonry buildings typical of the Totoracocha-Cuenca sector. In the first instance, under a scheme of definition of buildings-prototype and parametric analysis, their capacity curves will be obtained. And in the second instance, considering the building-program of average characteristics, its seismic performance will be evaluated in terms of the expected degree of damage, and the effect of its redesign using the guidelines of the Ecuadorian Standard of Construction (NEC 2015) and of the New Zealand seismic evaluation guides, section C7 (GESNZ-C7).
