Key scope of this research is evaluation of actions of beam to column joints under the impact load acting on it. The beam-column joints, a common area between frame beams and columns. It is the most critical zone to ensure the global response of such momentary resistance structures. Several approaches have been attempted over the years by many civil engineers and practitioners to improve the deficiently thorough joint in between beam and column. The highest bending moment and shear forces in the framed structures are at the junction area. As a result, that joint between beam and column is one of a collapse zone. Joint in outer is more important among the beam-column joints. The effect may be caused by a weight falling on the design object or possibly falling off the design object and hitting the hard surface. In this work, an emphasis has been made to understand the joint vulnerability against impact loads and its behavior is analyzed using the ANSYS software. From this experimental program observed that, impact resistance in RCC beam to column joints can be improved by improving stiffness by added polypropylene fibers and energy absorption can also be improved.
Este estudio evalúa las características de la durabilidad del ferrocemento mezclado con mortero de geopolímeros después de ser sometido al fuego. El ferrocemento fue preparado con mortero de geopolímeros y se comparó con el ferrocemento convencional preparado solo con mortero de cemento. Previamente, se estandarizó la concentración molar de la solución de hidróxido de sodio usada para preparar el mortero de geopolímeros mediante la resistencia residual de los cubos de mortero preparados con diversas concentraciones de NaOH. Se determinó y comparó la resistencia residual a flexión de probetas de hormigón preparadas con diferentes porcentajes en volumen (1,5%, 1,8% y 2,1%) de ferro-geopolímeros y ferrocemento, las que luego fueron sometidas durante dos horas a tres niveles de temperatura entre los 300°C y 900°C. Además, probetas con los mismos porcentajes en volumen fueron expuestas a temperaturas sobre los 900°C con el objetivo de determinar su resistencia residual al impacto. Se determinaron las características de la resistencia al fuego de las probetas en términos de Resistencia residual a flexión, resistencia residual al impacto y pérdida de peso. En todos los aspectos, las probetas preparadas con ferro-geopolímeros mostraron un comportamiento superior a las probetas convencionales de ferrocemento.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
