Evaluación técnica económica del diseño por desempeño de edificios con estructura de acero utilizando diversos tipos de arriostramientos laterales

Abstract

The main objective of this research is to analyze several steel buildings, which have different geometric characteristics, in which different types of bracing side such as: diagonal cross, diagonal in tip and shear walls of reinforced concrete; the structures are discussed with the Ecuadorian Norm Construction NEC-15 and AISC standards for the design of steel. It comes with analysis of vertical loads, to later evaluate the seismic force, taking into account the structural configuration and typology of each building. For the analysis software is used the Etab-13 and Sap2000 simulations. Met the minimum requirements as regards the linear analysis, it comes with non-linear analysis (Pushover Analysis) whose parameters are described in rules of FEMA, are obtained capacity curves (base shear vs lateral displacement). The is a referential budget of metal structures, in which it obtains the ratio of weight of structure on the area of construction; finally, it was seen that structure complies with technical and economic parameters.
