Bidirectional response ofWeak-Axis end-plate moment connections: numerical approach
(MDPI, 2020)
Brittle failure mechanisms can affect the seismic performance of structures composed of intersecting moment resisting frames, if the biaxial effects are not considered. In this research, the bidirectional cyclic response ...
Experimental behavior of a masonry wall supported on a RC twoway slab
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2015-11-01)
This paper discusses the experimental results of a prototype slab-wall that is subjected to vertical and horizontal cyclic loading. The key aspects under discussion are: (a) the differences between the capacity resistance ...
Test study on the influences of dynamic stress and load history to the dynamic properties of the remolded red clay
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2016-10-01)
The dynamic properties of subgrade materials are critical factors affecting stability within the traffic engineering discipline. Remolded red clays are frequently used as subgrade filling materials, however, to date, a ...
Sucker rod string design of the pumping systems
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2015-05-01)
The existing design of sucker rod string mainly focuses on the simplifying assumptions that rod string was exposed to simple tension loading. And its goal was to have equal modified stress at the top of each taper. The ...
Thermo-mechanical behavior of a granodiorite from the Liquine fractured geothermal system (39 degrees S) in the Southern Volcanic Zone of the Andes
(Elsevier, 2020)
Fractures and faults in granitic rocks play an important role in geothermal systems because they permit the circulation of hot fluids. However, the thermo-hydro-mechanical behavior of granitic rocks has predominantly been ...
Rehabilitación sísmica de muros de adobe de edificaciones monumentales mediante tensores de acero
(Pontificia Universidad JaverianaColombia, 2007)
Entre el año 2001 y el año 2003 el Grupo de Investigación en Materiales y Estructuras, grime, llevó a cabo una investigación exhaustiva de los sistemas constructivos de los monumentos históricos de los Andes colombianos ...
External strengthening of unreinforced masonry walls with polymers reinforced with carbon fiber
(Universidad Nacional de ColombiaBogotá, Colombia., 2018)
In many countries, buildings are usually made of unreinforced clay masonry walls, especially in Colombia. These constructions have low resistance and ductility, and are very vulnerable to seismic events, due to their low ...
Morpho-structural evolution of the Cordon Caulle geothermal region, Southern Volcanic Zone, Chile: Insights from gravity and Ar-40/Ar-39 dating
(ELSEVIER SCIENCE BV, 2005-11-15)
The Cordon Caulle geothermal region (40.5 degrees S) is a 13 km X 6 kin, NW-SE elongate, volcano-tectonic depression hosting numerous monogenetic volcanic centers, fumaroles, and hot-springs, most of which occur spatially ...
Desempeño ante cargas laterales de muros de mampostería no estructural reforzados con CFRP
(Universidad Escuela Colombiana de Ingeniería Julio GaravitoBogotá, 2015)
En muchos países son tradicionales las viviendas construidas con muros de mampostería en arcilla no reforzada, lo que da lugar a edificaciones de baja resistencia y ductilidad, muy vulnerables a eventos sísmicos debido a ...
