Evaluación y reforzamiento del sistema resistente a carga lateral de muros del ex colegio Simón Bolívar

Abstract

In Ecuador, there are many patrimonial structures, made up of fragile earth-based materials. Recent seismic events have revealed the poor performance of these structures, due to their large mass and low capacity to withstand loads outside their plane.

The present project, presents the evaluation of current state and reinforcement, through the modeling, based on finite elements, using computational software. For the modeling, a calibration of the finite mesh was carried out, which resulted in parametric values, such as the number of parts, the proportion of the element, with respect to itself and with respect to its main length, parameters such as the thickness of the Wall and the type of element to model (FRAME, SHELL, SOLID).

The current state of the structure, front of the design earthquake, was evaluated, taking into account experiences from neighboring countries, with similar seismic events, using the recommendations of its regulations, in combination with the Ecuadorian norm (NEC).

Reinforcement stages were proposed, focused on the reduction of stresses and control of displacements
