Diseño sismo-resistente de edificio metálico de 4 pisos, para uso oficinas - residencial en la ciudad de Manta.

Abstract

This present work analyzes the use of structural steel as a construction system in a four-story building in Manta, promoting its adoption as a technical and competitive alternative in the construction sector in Ecuador. Currently, reinforced concrete predominates due to factors such as costs and the limited offer of specialized services in steel structures, despite the advantages of steel in terms of efficiency and performance. The project proposes an earthquake-resistant structural design methodology for large-span metal buildings, applied to a commercial-residential building, complying with AISC 360-22 and NEC 2015 regulations. The design incorporates reinforced beams, concrete-filled steel columns, steel deck slabs, leveling grout, plates, anchor bolts and stiffeners in beams and columns. The results show that structural steel allows reducing the number of columns from 20 to 9 and the construction time from 120 to 80 days, in addition to offering advantages in weight, flexibility and seismic energy dissipation capacity. Although it implies a 29.6% increase in the cost of the gray work, the system has a positive environmental impact and is positioned as a viable alternative to reinforced concrete in Ecuador.
