Influencia de la presión en roturas de tubería de redes de distribución
(2016-09-01)Uno de los síntomas del deterioro de las redes de distribución de agua son las frecuentes roturas de tubería. Las gestoras del agua tratan de evitarlas en la medida de lo posible debido a los elevados costos económicos, ... -
Estudio experimental de la ductibilidad de soportes de hormigón convencional sometidos a compresión y carga lateral cíclica
(2009-12)Los soportes de hormigón armado que forman parte de una estructura sismorresistentes en lugares donde existen mayores riesgos de sismo, deben diseñarse con el objetivo de asegurar un adecuado comportamiento en cuanto a ... -
Determinacion de indicadores para la calidad del agua y sedimento marino no costero en la bahia de manzanillo
(2014-06)El Índice de Calidad de Agua (ICA) es una herramienta utilizada para conocer los atributos de un cuerpo de agua de acuerdo a sus distintos usos; sin embargo, su aplicación se ha dado principalmente en aguas continentales, ... -
Estudio teórico de capacidad de deformación de soportes esbeltos de hormigón armado con fibras de acero sometidos a esfuerzos combinados de axil y carga lateral
(2012-10)El estudio de la ductilidad es muy importante en elementos estructurales sometidos a esfuerzos combinados, ya que nos determina la capacidad de resistencia y a la deformación. Actualmente son escasos los ensayos experimentales ... -
Comportamiento de soportes esbeltos de hormigón armado con fibras de acero sometidos a esfuerzos combinados de axil y carga lateral cíclica
(2012-10)La ductilidad es un indicador de la capacidad de deformación en estructuras sometidas a esfuerzos combinados de axil y carga lateral cíclica. El elemento estructural sometido a estos esfuerzos debe ser capaz de absorber y ... -
Assessing resilience to climate change in the US cities
(2012-03-09)In the face of uncertainties associated with climate change, building adaptive capacity and resilience at the community level emerges as an essential and timely element of local planning. However, key social factors that ... -
An experimental study of steel fiber-reinforced high-strength concrete slender columns under cyclic loading
(2012-08-10)Structural engineers usually limit the use of HSC columns to seismic active zones because of their britle behavior in comparison with NSC, even though it presents advantages both in terms of mechanics and durability. A ... -
Behaviour of steel-fibre-reinforced normal-strength concrete slender columns under cyclic loading
(2012-03-28)The inclusion of ductility requirements is necessary to guarantee a safety design of concrete structures subjected to unexpected and/or reversal loads. It is important to outline that plastic hinges may develop in columns ... -
Seismic Response of Single-Degree-of-Freedom (SDOF) Structural Fuse Systems
(2004-06-26)Passive energy dissipation (PED) devices have been implemented to enhance structural performance by reducing seismically induced structural damage. In this paper metallic dampers are defined to be structural fuses (SF) ... -
Investigation of the Structural Fuse Concept
(2005-06-26)Passive energy dissipation (PED devices have been implemented to enhance structural performance by reducing seismically induced structural damage. In this paper metallic dampers are defined to be structural fuses (SF) when ... -
Seismic Design of Multi-story Buildings with Metallic Structural Fuses
(2006-06-28)Seismic design relies on inelastic deformations through hysteretic behavior. However, this translates into damage on structural elements, permanent system deformations following an earthquake, and possibly high cost for ... -
