Characterization of failures in school buildings exposed in aggressive environment M4 of Falcón State

The present investigation focused on establishing a characterization of public used reinforced concrete constructions such as school units in the coastal zone of Chichiriviche and Tucacas in Venezuela’s Falcon State, exposed to highly corrosive environments and built with inadequate construction tec...

The ultimate aim was to make recommendations to regional bodies so that they could make structural interventions more precisely and assertively. The study was carried out in seven educational units, in which planimetric surveys were carried out, the collection of fault symptoms, tests in some structural members and finally a general evaluation of damages that allowed identifying their durability and particular recommendations for each school building. As a result, these units of different construction ages were in a better state of conservation, when compared directly to the sample evaluated in 2006 in private multifamily buildings, which were even younger than this sample. It was recommended for all cases that they apply a programmed and technical continuous maintenance system, which goes beyond the systems of paints whose substrate is not properly prepared, resulting in a process of superficial repair and aesthetic ineffective. El presente estudio se centró en establecer una caracterización de edificaciones de concreto armado de uso público como las unidades escolares, en la zona costera de Chichiriviche y Tucacas, en el Estado Falcón, de Venezuela, expuestas a ambientes altamente corrosivos y edificados en base a prácticas constructivas inadecuadas. La finalidad última era la de aportar recomendaciones a los organismos regionales, a fin de que pudieran hacer las intervenciones estructurales de manera más precisa y asertiva. Se realizó el estudio en siete unidades educativas, en las que se efectuaron levantamientos planimétricos, levantamiento de síntomas de fallas, ensayos en algunos miembros estructurales y finalmente una valoración general de daños que permitió identificar su durabilidad y recomendaciones particulares a cada edificación escolar. Se obtuvo como resultado que dichas unidades de diversas edades de construcción se encontraban en mejor estado de conservación, si se compara directamente con la muestra evaluada en el 2006 realizada en edificaciones multifamiliares privadas, que eran incluso más jóvenes que ésta muestra. Se recomendó para todos los casos que aplicaran un sistema de mantenimiento continuo programado y técnico, que fuese más allá de los sistemas de pinturas que cuyo sustrato no está idóneamente preparado, teniendo como consecuencia un proceso de reparación superficial y estético poco efectivo.
