Evaluación del desempeño estructural de una torre para montaje mediante un análisis estático lineal y no lineal

Abstract

This thesis develops the geometric non-linearity topic applied to an assembly tower for the cable-stayed arch bridge with a 120-meter span. Where he designed a methodology that he included: the contextualization of the type of structure in front of other structural models; determining the types of gravitational or environmental loads to which the towers of its class are exposed; and finally, the comparative analysis of the results achieved with a linear and non-linear model of the tower itself through the SAP2000 software. He took as a reference the considerations and calculations applied to both the cables and the pile tower itself of a cable-stayed bridge. Through a recognition of the type of non-linearity that the tower was presenting, and the characterization of the deformation of the cables in the SAP2000, it was possible to determine the gradual deformation that the tower experienced at two reference points (tower cusp and the counterweight point), due to the influence of the weight of the arches of the bridge. Finally, an average displacement difference of 13.6 mm was obtained between the nonlinear versus the linear analysis.
