Resumo: | The phenomenon of subsidence caused by the extraction of groundwater is a problem that occurs in different places around the world. Particularly in the Mexican Republic is a situation that affects several cities in at least eight states located in the central region. Given the particular nature of the subsoil that occurs in these regions affected, subsidence can generate cracks and fractures that are evident on the surface of the soil causing differential settlement affecting all types of construction causing considerable damage to the structural elements of the dwellings. The materials traditionally used for housing construction such as masonry and concrete among others, have stiffness characteristics that make them especially vulnerable to these effects. In contrast, steel is an excellent choice for use due to their structural characteristics, such as its high tensile strength, ductility, compressive good performance, high efficiency in weight — strength ratio, among other qualities. The cold formed thin-walled steel elements, are another type of very light profiles, although its use has been known for several decades, is in recent times that have extended their application, mainly in housing construction, and to a lesser scale commercial and industrial construction. The main advantage of this material is that it retains the mechanical properties of steel, but with a significant reduction in the weight of the items. The most common use of this type of profile is in the manufacture of structural frames as standard modules, the most common form it is assembly profile channel with rigid edge section and section profiles of single channel, with different dimensions and sizes. In full-scale testing and numerical simulation models, the system exhibits an excellent performance under differential displacements as those caused by subsidence, accepting considerable deformations without reaching the failure of structural elements. In the goodness of this behavior is observed thin-walled cold formed steel, first by its deformation without collapse and second for being a sustainable system that causes less harm to the environment compared to traditional buildings. Therefore exposure is considered that this system is an excellent choice for use in housing construction in areas with subsidence. |

Particularmente, en la República Mexicana es una situación que afecta varias ciudades en por lo menos ocho estados localizados en la zona central del país. Por las caracterís-ticas del subsuelo que se presenta en estas regiones afectadas, la subsidencia puede llegar a generar grietas y fracturas que se hacen evidentes en la superficie del suelo provocando asentamientos diferenciales que afec-tan todo tipo de construcción causando daños considerables en los elementos estructurales de las viviendas. Los materiales tradicionalmente empleados para la construcción de viviendas tales como la mampostería y el concreto entre otros, presentan características de rigidez que los hacen especialmente vulnerables ante es-tos efectos. En contraste, el acero representa una excelente opción de uso debido a sus características estruc-turales, como es su alta resistencia a la tensión, ductilidad, buen comportamiento a la compresión y su alta eficiencia en su relación peso-resistencia, entre otras cualidades. Los elementos de acero formado en frío de pared delgada, son otro tipo de perfiles muy ligeros, que aunque su uso se conoce desde hace algunas déca-das, es en tiempos recientes que han extendido su aplicación, principalmente en la construcción de viviendas, y en menor escala en la construcción comercial e industrial. La principal ventaja de este material es que con-serva las características mecánicas del acero pero con una reducción importante en cuanto al peso de los elementos. El uso más frecuente de este tipo de perfiles es en la fabricación de marcos estructurales en forma de módulos estándar, cuyo ensamblaje más común es formarlo con perfiles de sección; canal con borde rígi-do y perfiles de sección, canal simple, con diferentes dimensiones y calibres. En pruebas experimentales a es-cala real y en modelos de simulación numérica el sistema presenta un excelente comportamiento ante los desplazamientos diferenciales como los provocados por la subsidencia, aceptando deformaciones considera-bles sin sufrir daños apreciables y con una capacidad portante muy adecuada. En este comportamiento se observa la bondad del acero formado en frío de pared delgada, primero por su capacidad de deformación sin colapso y segundo por ser un sistema sustentable que causa un menor impacto al ambiente, en comparación con las construcciones tradicionales. Por lo anterior expuesto, se considera que este sistema constructivo-estructural puede ser muy adecuado para reducir daños y garantizar la seguridad estructural en viviendas construidas en zonas afectadas por hundimientos diferenciales debidos a agrietamientos del suelo asociados al fenómeno de subsidencia.Universidade Estadual de Campinas2014-04-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAnálise descritivaapplication/pdfhttps://periodicos.sbu.unicamp.br/ojs/index.php/labore/article/view/21410.20396/lobore.v8i2.214Labor e Engenho; Vol. 8 No. 2 (2014): abr./jun.; 52-61Labor e Engenho; Vol. 8 Núm. 2 (2014): abr./jun.; 52-61Labor e Engenho; v. 8 n. 2 (2014): abr./jun.; 52-612176-8846reponame:Labor & Engenho (Online)instname:Universidade Estadual de Campinas (UNICAMP)instacron:UNICAMPspahttps://periodicos.sbu.unicamp.br/ojs/index.php/labore/article/view/214/pdf_110BrasilCopyright (c) 2015 Labor & Engenhoinfo:eu-repo/semantics/openAccessHernádez Castillo, Luis AlfredoOrtiz Lozano, José Ángel2019-07-27T06:03:26Zoai:ojs.periodicos.sbu.unicamp.br:article/214Revistahttp://periodicos.sbu.unicamp.br/ojs/index.php/laborePUBhttps://periodicos.sbu.unicamp.br/ojs/index.php/labore/oai||argollo@fec.unicamp.br2176-88461981-1152opendoar:2019-07-27T06:03:26Labor & Engenho (Online) - Universidade Estadual de Campinas (UNICAMP)false |
