| description | In housing, concrete masonry is one of the most used construction systems in Costa Rica. Under this construction system, beams and columns of equal width (12 or 15 cm) are usually required. In these cases, constructively, bending the reinforcing steel of the beam or column is used. This type of bend used“strangles” the reinforcement right in the section of maximum moment. Thus, it is relevant to experimentally investigate the behavior of these joints that are typically observed in constructions.The behavior of joints with two different reinforcement details and with 12 cm thick elements for use in housing was analyzed. Four joints were built, two with a “bottleneck” reinforcement detail(Type A Joint) and two with a 1:6 slope detail (Type B Joint). These were failed in the LanammeUCR Structures Laboratory under the application of a pseudo dynamic cyclic load. Rotations were calculated and the hysteresis curve and elastoplastic curve were constructed for each joint. The behavior of the twotypes of joints was compared, as well as the experimental capacity results with respect to the expected theoretical capacity.The results obtained show that Type A Joints do not reach the calculated theoretical capacity and present a less ductile behavior than Type B Joints. It was concluded that it is preferable and advisable to use beam-column joints with the slope detail 1:6 as part of the earthquake-resistant system of a home. |

En vivienda, la mampostería de concreto es uno de los sistemas constructivos más utilizados en Costa Rica. Bajo este sistema constructivo, se suelen requerir vigas y columnas de igual ancho (12 o 15 cm). En estos casos, constructivamente se recurre a doblar el acero de refuerzo de la viga o de la columna. Este tipo de doblez utilizado “estrangula” al refuerzo justo en la sección del máximo momento. De tal forma, resulta relevante investigar experimentalmente el comportamiento de estas uniones que típicamente se observan en las construcciones.Se analizó el comportamiento de uniones con dos distintos detalles de armado y con elementos de 12 cm de espesor para uso en vivienda. Se construyeron cuatro uniones, dos con un detalle de armado de “cuello de botella” (Unión Tipo A) y dos con detalle de pendiente 1:6 (Unión Tipo B). Estas se fallaron en el Laboratorio de Estructuras del LanammeUCR bajo la aplicación de una carga cíclica pseudo dinámica.Se calcularon rotaciones y se construyeron la curva de histéresis y la curva elastoplástica para cada unión. Se comparó el comportamiento de los dos tipos de uniones, así como, los resultados de capacidad experimentales con respecto a la capacidad teórica esperada.Los resultados obtenidos muestran que las Uniones Tipo A no alcanzan la capacidad teórica calculada y presentan un comportamiento menos dúctil que las Uniones Tipo B. Se logró concluir que es preferible y recomendable utilizar uniones viga-columna con el detalle de la pendiente 1:6 como parte del sistema sismorresistente de una vivienda.
