“…This is also corroborated by previous research conducted in this topic, concluding that using a rigid assumption for this type of RC building floor diaphragms may give non-conservative results [18,20,25].…”

“…Al Harash et al [25] investigated the effect of diaphragm openings and flexibility (versus rigid assumption) on seismic response of five 3-story RC buildings with end shear walls having plan aspect ratios of 4:1 using a damage computational tool (IDARC 2). Results indicated that inelastic in-plane floor deformations caused by presence of openings led to erroneous and non-conservative results when compared to the cases where rigid floor assumption with no openings were analyzed.…”

“…Sin embargo, para relaciones de aspecto mayores a 2.0, el diafragma ya deja de ser suficientemente rígido y su flexibilidad no debería despreciarse (Panahshahi et al 1991, Saffarini y Qudaimat 1992, Ju y Lin 1999, Doudoumis y Athanatopoulou 2001, Barron y Hueste 2004, Bal y Ozdemir 2006, Al Harash et al 2008, Moeini y Rafezy 2011. En contraste, no se puede afirmar la condición de diafragma rígido para distintas relaciones de aspecto o espesores relativamente reducidos de lo que se conoce como "firme de compresión" para otros sistemas que ya tienen un tiempo razonable de uso en el mercado mexicano, como la losa plana reticular aligerada (Chen 1986, Chen et al 1988, Rodríguez et al 1995, la vigueta y bovedilla (Damian et al 2000), la losacero (Sarkissian et al 2006), sobre todo si no cuenta con un "firme de compresión" (Paulte et al 2004, Mastrogiuseppe et al 2008, o los nuevos sistemas que están teniendo una gran demanda en estos días, como las losas planas aligeradas con bloques de espuma de poliestireno de grandes dimensiones (de un metro por un metro, incluso más largos), situación que puede conducir a una reducción importante de su rigidez y resistencia ante cargas laterales.…”

“…Las configuraciones irregulares en planta (Ju y Lin 1999, López y Raven 1999 Athanatopoulou 2001, Moeini y Rafezy 2011) y la presencia de aberturas importantes en los sistemas de piso (Doudoumis y Athanatopoulou 2001, Al Harash et al 2008, Öztürk 2011 también favorecen el desarrollo de la flexibilidad de los diafragmas.…”

“…Al Harash et al [10,11] studied in uence of diaphragm openings on buildings with three types of oor diaphragm models, namely rigid, elastic, and inelastic. The results illustrate that interior frames absorb more shear when there are openings in diaphragm since in-plane diaphragm deformation is greater in this situation.…”
