Diseño estructural en condiciones de incendio del sistema de entrepiso del edificio “Torino” aplicando un método de cálculo basado en la modelación estructural del edificio

Abstract

In the present work the modeling of composite beams to fire conditions is developed, where it is sought to obtain the degradation of the resistant capacity both shear force and the bending moment of the same. Consequently, the results obtained by comparing those calculated by means of three foreign regulations in a previous technical work were validated, such as: EUROCODE, BRAZILIAN NORM and AISC. To perform the numerical modeling using the FEA software, the main features that the program offers in terms of thermal and structural modeling were reviewed, in order to simulate the “TORINO” building’s steel-concrete floor system so that all considerations can be closest to reality. Through the comparative analysis from the technical point of view, it was decided to propose some fire protection alternatives in the steel-concrete floor systems, with the purpose of improving its behavior under fire conditions. Finally, an economic assessment of the fire protection was carried out to determine in these terms the best option.
