Análisis estructural del comportamiento de una edificación mixta de tres niveles con pórticos de hormigón armado y vigas secundarias de madera laminada utilizando diferentes programas especializados para el análisis estructural

Abstract

This study proposes a structural analysis and design alternative for the mixed structure construction system that is currently being widely used as a construction alternative in Ecuador. The proposal is a combination of reinforced concrete frames and laminated timber secondary beams with a deck type slab, with a metal plate connection between secondary beams and main beams. Specialized structural analysis programs such as ETABS, SAP2000 and Robot Structural will be used for the modeling, analysis and design of the building, The Structural Safety chapter NEC-SE-HM, 2015 was used for the moment resisting portal frames and the considerations of the Chilean standard will be used for the secondary glulam beams, since there is no specific standard for these elements subjected to bending. For this purpose, the minimum requirements of the Seismic Resistant Design specified in the Structural Safety chapter of NEC-SE-DS, 2015 were met. In order to compare, analyze and discuss the results obtained with the software, to recommend the design methodology for this type of structures.
