Diseño estructural para construir un edificio aporticado con muros de corte de 5 pisos aplicando la Norma Ecuatoriana de la Construcción NEC- SE,2015, ubicado en la parroquia Cotocollao, barrio 23 de junio, provincia de Pichincha

Abstract

This project analyzes the values of drifts, torsion and vibration periods produced by seismic loads for the framed system with shear walls of a five-story building for which a structural analysis was carried out based on the (Norma Ecuatoriana de la Construcción NEC-SE-DS, 2014), which involves the review of the design parameters for columns, beams, slabs and shear walls. Next, the design loads are determined according to the use of the building as indicated in the regulations, the calculation by own weight is included according to the number of floors of the project and the percentage of the seismic action to which it is determined is determined. The structure will be subjected when the seismic load acts. With these values, the pre-design of structural elements is carried out with electronic sheets where minimum sections will be assumed to start the process. With these data, a mathematical modeling of the structure is made in the Etabs V21.2.0 computer program, the design regulations to be used are determined, the loads, types of materials and previously calculated sections are defined. In addition, the load combinations indicated by the regulations are entered, the calculated basal shear value is entered and the program is run to perform the Static Linear Analysis and Dynamic Linear Analysis (Modal Spectral). This will verify that the building meets the minimum design requirements and that the values obtained from inelastic drifts for the static and dynamic earthquake are below the maximum values, which is 2%, and that the mass participation is at least 90%. %, that the first two vibration modes must be translational and the third rotational and that the value of T_E≤T_N*1.30. Subsequently, the moment, shear, and axial diagrams are obtained; according to the values, the maximum amount is designed for each structural element. Finally, we proceed with the structural detailing through the definitive design of two frames in each direction in the computer program and the respective detailed engineering plans are made.
