Technical and economic analysis of design for performance of buildings with steel structure using concentric bracings

This paper presents the analysis of ten structural models of steel structure buildings, using different lateral concentric arches, with software Etabs-16 and Sap2000. to make an observation of the results obtained from the linear and non-linear analysis (Pushover) of the models; taking into consider...

Se proyectó realizar una observación de los resultados obtenidos del análisis lineal y no lineal (Pushover) de los modelos, tomando en consideración el cumplimiento de los parámetros mínimos establecidos en la Norma Ecuatoriana de la Construcción NEC-15, en lo referente a la evaluación del cortante basal y controles para que las estructuras sean consideradas sismorresistentes. Se obtienen los diseños definitivos tomando como referencia la norma American Institute of Steel Construction, y en base a los resúmenes de materiales en los que se detallan índices entre el peso total y el área de las estructuras se elaboraron presupuestos referenciales, como consecuencia se realizó una evaluación económica para determinar qué tipo de arriostramiento concéntrico resulta ser el más beneficioso en cuanto a costos. Los resultados obtenidos indicaron que la alternativa más económica corresponde a la utilización de muros de corte de hormigón armado, en la que se puede obtener un ahorro que oscila desde 14,18% hasta 17,34% con la utilización de las otras alternativas de arriostramientos Universidad Centroccidental Lisandro Alvarado - Decanato de Ingeniería Civil 2019-01-31 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo científico de investigación original application/pdf https://revistas.uclave.org/index.php/gt/article/view/2080 10.13140/RG.2.2.20052.86409 Gaceta Técnica; Vol. 20 No. 1 (2019): January-June; 41-59 Gaceta Técnica; Vol. 20 Núm. 1 (2019): Enero-Junio; 41-59 Gaceta Técnica; v. 20 n. 1 (2019): January-June; 41-59 2477-9539 spa https://revistas.uclave.org/index.php/gt/article/view/2080/1146 https://revistas.uclave.org/index.php/gt/article/view/2080/1209 https://revistas.uclave.org/index.php/gt/article/view/2080/1329
