La figura muestra la estructura de un panel publicitario digital (Pilar tubular cuadrado hueco y cimentación de concreto armado de peso equivalente a 3.5 veces el peso de la superestructura). La pantalla led es de peso 65 kg/m2. La densidad del acero estructural es 7850 kg/m3. Se conoce que la presión del viento sobre la pantalla es de 30 kg/m2 actuando de forma perpendicular sobre esta. Se pide determinar el ancho mínimo B para que el esfuerzo sobre el terreno debido a las cargas actuantes no sea mayor a 5 ton/m2.Considere una distribución constante de presiones. Haga un esbozo de la presión del suelo sobre la cimentación e indique la longitud apoyada sobre el terreno. Consideré que el peso de la pantalla led se aplica en el centroide del perfil tubular.
