Rigidez de una conexión de columna-cimentación para estructuras de Guadua angustifolia Kunth
(Universidad de la Salle, 2014)
Una de las limitantes que encuentran los ingenieros estructurales para el diseño de una edificación y, en general, de cualquier estructura en Guadua angustifolia Kunth es la falta de información técnica relacionada con ...
Análisis de estructuras
(Universidad de los Andes, 1991)
Properties prediction of environmentally friendly ultra-highperformance concrete using artificial neural networks
(Taylor and Francis, 2020)
Ultra-high-performance concrete (UHPC) results from the mixture of several constituents, leading to a highly complex material in both, fresh and hardened state. The higher number of constituents, together with a higher ...
Observation of significant differences between electromagnetic and acoustic emissions during fracture processes: A study on rocks under compression loading
(IOP Publishing Ltd, 2019)
Electromagnetic radiation (known as electromagnetic emissions) related to processes of loading and fracture in different types of materials (from metals to rocks) has been widely reported. The physical mechanisms behind ...
Utilización de agregado grueso de concreto reciclado en elementos estructurales de concreto reforzado
(Escuela Colombiana de Ingeniería Julio Garavito, 2014)
Rehabilitación sísmica de muros de adobe de edificaciones monumentales mediante tensores de acero
(Pontificia Universidad Javeriana, 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 ...
Performance under sulfate attack of concrete additioned with fluid catalytic cracking catalyst residue (FCC) and metakaolin (MK)
(Universidad Nacional de Colombia, 2013)
In this work the evaluation of the performance of concrete added with Fluid Catalytic Cracking Catalyst residue (FCC) from a Colombian petroleum company, under sulfate attack, is presented. The results of this concrete are ...
Factorial design of reactive concrete powder containing electric arc slag furnace and recycled glass powder
(Universidad Nacional de Colombia, 2020)
The main objective of this research is to develop an optimized mixture of reactive powder concrete (RPC) containing supplementary cementitious materials (SCM), such as Electric Arc Slag Furnace (EASF), and Recycled Glass ...
External strengthening of unreinforced masonry walls with polymers reinforced with carbon fiber
(Universidad Nacional de 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 ...
Comparative analysis of acoustic emissions produced in abrupt and non-abrupt fracture processes in reinforced concrete walls
(IOP Publishing Ltd, 2023)
The determination of the eventual abrupt fracture of a reinforced concrete structure is of fundamental importance to estimate and mitigate the possible damages caused by its failure; of particular importance are shear-type ...
