un nuevo metodo de diseno de losas para pisos industriales ante la inaplicabilidad de los metodos simplificados de diseno entre ellos los de la Portland Cement Association pca y wire reinforCement institute wri
Revista Ingenieria E Investigacion, 2007Co-Authors: Camero Sanabria, Hugo ErnestoAbstract:Se presenta una metodologia para el diseno de losas sobre terreno para pisos industriales en donde hay excentricidad entre el centroide de la losa y el centro de gravedad de las cargas del ele cargado del montacargas que transita sobre el piso. Mediante un ejemplo se analiza como los metodos de diseno de pisos de la Portland Cement Association (PCA) y la Wire ReinforCement Institute (WRI) son inadecuados para el diseno de pisos sometidos a esta condicion. El nuevo metodo propuesto para disenar pisos industriales ha sido llamado Camero. Mediante un ejemplo, un piso industrial es disenado para ser capaz de admitir un numero infinito de aplicaciones de carga (o un periodo de vida util del piso de 50 anos), comparando los resultados del metodo Camero y los simplificados de la PCA y la WRI. El piso industrial sera capaz de admitir un numero infinito de aplicaciones de carga (50 anos) si es disenado con el metodo Camero. De otra manera: si es disenado por los metodos de la PCA y la WRI unicamente durara un ano (En este ejemplo, en el periodo de un ano el numero de aplicaciones del ele cargado es igual al numero de repeticiones admisibles), por eso el piso industrial no sera capaz de admitir un numero infinito de aplicaciones de carga. Concluimos que el diseno de losas sobre terreno de concreto simple (sin refuerzo), de acuerdo con la metodologia de la PCA y la WRI, conduce a losas disenadas a fatiga, a pesar de haber considerado en el diseno que el esfuerzo en las fibras superiores no excederia el 50% del modulo de rotura del concreto y que admitirian un numero infinito de repeticiones de carga (numero infinito de transito del montacargas de diseno).

A new method for designing floor slabs on grade due to the difficulty of applying simplified design methods, amongst them being the Portland Cement Association (PCA) and Wire ReinforCement Institute (WRI) methods
Revista Ingenieria E Investigacion, 2007Co-Authors: Camero Sanabria, Hugo ErnestoAbstract:This article presents a methodology for designing slabs on grade for industrial floors where there is an eccentricity between the slab centroid and the gravity centre loads of the loaded axle of forklift trucks travelling over the floor. An example was used for analysing how Portland Cement Association (PCA) and the Wire ReinforCement Institute (WRI) methods are inadequate for designing floors subjected to this condition. The new proposal for designing slabs on grade for industrial floors has been called the Camero method. An example of an industrial floor designed to be capable of sustaining an infinite number of load applications (or 50-year life) was compared to the results of the Camero method and PCA and WRI’s simplified methods. Industrial floors should be capable of sustaining an infinite number of load applications (50-year life) if designed with the Camero method; on the other hand, if designed using PCA and WRI methods they will only last one year (in this example the number of axle load applications in a 1-year period was equal to the number of allowable repetitions) because they will not be able to sustain an infinite number of load applications. It was concluded that designing plain concrete slabs (without reinforCement) on grade according to PCA and the WRI methods leads to slab fatigue, even though extreme fibre stress should not exceed 50 percent (50%) of static modulus of concrete rupture and slabs should sustain an infinite number of load repetitions (infinite amount of forklift truck traffic) were considered parameters in their design.
