Simulación numérica de los apoyos de puente metálico giratorio // Numeric simulation of gyratory metallic bridge supports
Abstract
En el presente trabajo se muestran algunos de los resultados del análisis realizado a los
mecanismos de apoyo, de cierre y de giro del puente metálico del municipio Playa en ciudad de La
Habana (popularmente conocido como “Puente de Hierro”), como parte inicial de un proyecto más
amplio que abarcará la reparación de todo el puente. El mismo tiene más de 100 años de explotación
(desde 1906) y con un mantenimiento casi nulo, lo que ha traído como consecuencia un considerable
deterioro del puente. En éste artículo se describen las principales características y patologías
detectadas al inspeccionar los mecanismos mencionados anteriormente y se presentan además, los
resultados de la simulación numérica de uno de los ensambles de piezas del mecanismo de apoyo.
Esta simulación arrojó que el apoyo puede trabajar con una seguridad adecuada.
Palabras claves: puente, modelación, análisis estructural y modelación, resistencia de materiales.

Abstract
Presently work some of the results of the analysis carried out to the mechanisms of support, of
closing and of turn of the metallic bridge of the Beach district in Havana city (popularly known as "Iron
Bridge") are shown, like initial part of a wider project that will include the repair of the whole bridge.
This has more than 100 years of exploitation (from 1906) and with an almost null maintenance, that
has resulted in a considerable deterioration o f the bridge. In this article the main ones characteristic
and pathologies detected when inspecting the mechanisms mentioned previously are described and
also are presented, the results of the numeric simulation of one of assembles of pieces of the support
mechanism. This simulation profited that the support can work with an appropriate security.
Key words: bridge, structural analysis and modeling, strength of materials.
