Evaluación del comportamiento estructural de conexiones semirrígidas unión viga - columna sometida a flexión mediante el análisis por elementos finitos

Abstract

The present work deals with the analysis and design a structure with four sections and five levels, the same one that is simulated in the STAAD PRO Software, with which data on moments and forces of each structural element of the building are obtained, Thus finding the most unfavorable gantry when applying dead, live and accidental loads, all under the regulations corresponding to the design by the ASD method, the national standards such as the NEC 2015 and the general standard AISC 360-16 are taken as reference standards. On the other hand, the design and analysis of the end plate semi-rigid connection takes place in the Idea StatiCa software, which allows the creation of the connection based on pre-existing models, the program simulates and develops with data exported from the software STAAD PRO the entire connection providing data of equivalent stress, local buckling, bolt design, welding, end plate, more unfavorable results of the internal and external connection are appreciated having as relevance data of equivalent stress of 150.2 MPa which represents a maximum equivalent plastic deformation percentage of 0.7%, does not present failure and the maximum values are 248.3 MPa and 5% respectively. A plastic deformation in the end plate of the external and internal connection of 3.4 and 2.5% is also observed, as the plate has been correctly optimized until reaching a thickness of 14 mm, these deformation values do not represent any failure.
