Analytical solution for the dynamic study of non-uniform cylindrical piles with generalized end conditions in non-homogeneous elastic soil
Cordoba Ordoñez, Andres FelipeThis paper presents a simplified analytical method for the dynamic study of non-uniform cylindrical piles with generalized end conditions in non-homogeneous elastic soil. The governing differential equation (GDE) of the ... -
Aumento de la profundidad de exploración implementando el método de la “correlación cruzada” de registros pasivos obtenidos por medio de geófonos comerciales de 4.5Hz
López Ruiz, EstebanEste trabajo presenta la implementación de la técnica de la “Correlación Cruzada” en registros pasivos tomados con geófonos comerciales de 4.5 Hz para definir las propiedades de dispersión representadas en un modo fundamental, ... -
Constitutive model evaluation for predicting the mechanical behavior of a residual igneous soil in the south of the Aburrá Valley
Valencia Cifuentes, Daniel FernandoThe dynamic growth shown by cities has generated an accelerated reduction in useful areas and therefore the need to optimize space. This implies the need to execute works with special conditions such as important excavations, ... -
Influence of concrete material time-dependency and temperature on the performance of a cofferdam structure braced with braces with reinforces concrete ring beams
Velásquez Pérez, AlejandroAsbstract: The lateral load resisting system of tall buildings is often made of reinforced concrete shear walls that are constructed using a cofferdam structure. The term cofferdam, often used in offshore applications, is ...Universidad Nacional de Colombia Sede Medellín Facultad de Minas Escuela de Ingeniería Civil. -

Numerical evaluation of concrete time-dependent effects on urban cofferdams
Aguirre Molina, Dumas AlejandroCurrent construction methods for high-rise buildings combine a temporary cofferdam structure with top-down excavation techniques. The cofferdam allows the construction of the building rigid concrete core foundations in ...Universidad Nacional de Colombia Sede Medellín Facultad de Minas Escuela de Ingeniería Civil. -
Parametric analysis in deep urban excavations using fully coupled flow-deformation analysis
Ballesteros Luna, Camilo AntonioCurrently, the implementation of advanced methods for the analysis of deep urban excavations such as the Fully coupled flow-deformation analysis that enables to simultaneously calculate stress, deformations and pore water ...Universidad Nacional de Colombia Sede Medellín Facultad de Minas Escuela de Ingeniería Civil.
