Resumen
Este trabajo de titulación tiene como objetivo el estudio del comportamiento en la conexión viga columna de un edificio de 10 pisos diseñado en acero estructural ASTM A992 de Grado 50 con sistema de pórticos resistentes a momentos. En el diseño se usarán conexiones soldadas precalificadas y posteriormente se comprobará si las mismas cumplen con las disposiciones sísmicas de acuerdo con el capítulo j del código AISC 360-10, AISC 341-10, AISC 358-10 y la norma NEC 2015, las mismas que indican que una conexión que une a miembros que pertenezcan a un sistema resistente a cargas sísmicas debe ser diseñada de tal forma que el estado límite dúctil sea quien controle el diseño ya sea en los miembros o en la conexión. La edificación es una estructura nueva, diseñada para para este proyecto. Se asumió que se encuentra en la ciudad de Guayaquil sobre un suelo tipo D y su importancia será de uso residencial. El predimensionamiento de las columnas y vigas que son los elementos principales es calculado conforme a el plano arquitectónico realizado mediante el Software AutoCAD 2016, para el predimensionamiento y análisis de las vigas principales y secundarias se usó el Software SAP 2000, el análisis dinámico se lo realizó con el Software ETABS 2016, las cargas gravitacionales para el pre diseño y el análisis estático se las calculó mediante los capítulos NEC-SE-CG Y NEC-SE-DS de la NEC-2015, para el análisis sísmico de las secciones escogidas se verificó que cumplan con los requerimientos del código AISC 341-10 según recomienda la norma NEC-2015 en el capítulo de estructuras de acero (provisiones sísmicas), los perfiles escogidos para el diseño de la edificación y que cumplen con los requerimientos fueron el IPE 500 para las vigas principales e IPE 200 para las vigas secundarias, las columnas son rectangulares tipo cajón sin relleno. Realizado el diseño de la edificación, con los resultados obtenidos se analiza y diseña teóricamente la conexión viga columna precalificada para garantizar que cumpla con los requisitos de diseño como son los de capacidad de disipación de energía y ductilidad según AISC 358-10 y posteriormente se realiza el diseño digital en el software RAM Connection 2016 con los datos geométricos para la conexión obtenidos del diseño teórico.
Al final, una vez que se desarrolló la investigación, se realizan las recomendaciones y conclusiones.
This titration work aims to study the behavior in the column beam connection of a 10-story building designed in ASTM A992 Grade 50 structural steel with moment-resistant gantry system. Pre-qualified welded connections will be used in the design and subsequently it will be checked if they comply with the seismic provisions in accordance with chapter j of the AISC 360-10, AISC 341-10, AISC 358-10 and NEC 2015 standards, the same that indicate that a connection that unites members belonging to a system resistant to seismic loads must be designed in such a way that the ductile limit state is the one who controls the design either in the members or in the connection.The building is a new structure, designed for this project. It was assumed that it is located in the city of Guayaquil on a type D floor and its importance will be for residential use. The pre-sizing of the columns and beams that are the main elements is calculated according to the architectural plan made using the AutoCAD 2016 Software, for the pre-sizing and analysis of the main and secondary beams the SAP 2000 Software was used, the dynamic analysis was performed With the 2016 ETABS Software, gravitational loads for pre-design and static analysis were calculated using NEC-SE-CG and NEC-SE-DS chapters of NEC-2015, for the seismic analysis of the selected sections that meet the requirements of the AISC 341-10 code as recommended by the NEC-2015 standard in the chapter of steel structures (seismic provisions), the profiles chosen for the design of the building and that meet the requirements were the IPE 500 for the main beams and IPE 200 for the secondary beams, the columns are rectangular type drawer without padding.Once the design of the building has been carried out, with the results obtained, the pre-qualified column beam connection is analyzed and theoretically designed to ensure that it meets the design requirements such as energy dissipation capacity and ductility according to AISC 358-10 and subsequently performed the digital design in the RAM Connection 2016 software with the geometric data for the connection obtained from the theoretical design.In the end, once the research was developed, recommendations and conclusions are made.
