En esta investigación se llevan a cabo análisis no lineales paso a paso para estudiar el comportamiento de fachadas prefabricadas de concreto del tipo &#8220;piso a piso&#8221;, las cuales han presentado fallas y desprendimientos aun cuando la estructura no ha sufrido daño. Para alcanzar este objetivo, se evalúan los desplazamientos y aceleraciones de cada uno de los pisos de un edificio de 15 niveles y 4 crujías, donde se calcula el nivel de daño de diferentes paneles. Para obtener estas respuestas, se diseña el sistema estructural mencionado utilizando el Apéndice A de las Normas Técnicas Complementarias para Diseño por Sismo del Reglamento de Construcciones del Distrito Federal del 2004 y se realiza un análisis dinámico incremental utilizando el registro sísmico del sismo de Michoacán del 19 de septiembre de 1985, obtenido en la estación de la Secretaría de Comunicaciones y Transportes. Se observa que al reducir las fuerzas sísmicas por ductilidad y sobrerresistencia, se podrían ignorar las fuerzas reales durante un sismo que son mayores a las de diseño, lo que podría provocar daño en las fachadas estudiadas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract During recent earthquakes in Mexico, it has been observed that despite a proper behavior of the structure, there are failures and damage among non-structural elements. This paper presents analytical time-history analysis and results of the seismic behavior of &#8220;floor to floor&#8221; precast concrete facades. This analysis includes the evaluation of accelerations and displacements at the supports of the panels in a 15-story building. For the structural design, the 2004 Mexico City code has been used. An incremental dynamic analysis was carried out using the record of the 1985 earthquake at the site SCT. It has been observed that after reducing the seismic design forces by ductility and over strength, it may be possible to ignore that the actual forces are larger than the design forces, which may cause damage to the precast concrete facades.]]></p></abstract>
