Evaluación de la conexión precalificada: viga de sección reducida-columna cajón relleno, para pórticos de momento a base de planchas de acero A36 soldadas

Abstract

The present project aims to evaluate the behavior of the beam-column prequalified connection for steel building and to determine if it meets ductility requirements and energy dissipation capacity, considering that our country is in a high seismic zone. The pre-design of main elements beams and columns, is made based on the architectural plans of the Jade building, later the ETABS software is used and the requirements of the Ecuadorian Construction Standard NEC to model and perform the Static Analysis. Finite element analysis of the beam-column outer connection is carried out using the SOLIDWORKS software, which predicts its behavior and observes critical areas of the connection. In the workshop, the beam and column is fabricated in real scale. The casting of the concrete of the column is made. The welding of the connection is executed by emulating actual positions and environments on site, all according to the requirements of AISC Codes 341-16, AISC 358-16, FEMA 350, AWS D1.1-15. The experimental trial is developed at the CIV-EPN Housing Research Center following the requirements of AISC 341-16 and FEMA 350. Subsequently the external connection is evaluated according to the criteria of AISC Code 341-16.
