Comportamiento de la mampostería bajo esfuerzos cortantes debido a efectos sísmicos Diego Fernando Páez- M Ingeniería deriva bloque ladrillo distorsión Mampostería En el presente trabajo se evalúa la incidencia tanto de las unidades mampuestas como del espesor de junta, en el comportamiento de la mampostería no reforzada, característica de la ciudad de Tunja, cuando se ve sometida a esfuerzos cortantes a causa de eventos sísmicos. Se encontró que la resistencia al corte se ve influenciada por la rugosidad de los ladrillos pues afecta la adherencia entre la pieza y el mortero. Se observó una incidencia notable del espesor de pega vertical en los muros de bloque N°5, pues aquellos con pega vertical prácticamente doblaron en resistencia a los muros sin pega vertical. Las distorsiones angulares registradas están por debajo de 0.5%, valor estipulado en la NSR-98. Además de las variables estudiadas, el comportamiento a cortante de la mampostería depende de otros parámetros que se recomienda tener en cuenta 2006 artículo científico 1692-3324 https://www.redalyc.org/articulo.oa?id=75050808 es http://www.redalyc.org/revista.oa?id=750 Revista Ingenierías Universidad de Medellín application/pdf Universidad de Medellín Revista Ingenierías Universidad de Medellín (Colombia) Num.8 Vol.5
