Evaluación estructural de elementos de madera tensada aplicados a la construcción de viviendas
(2016) Mauricio Vargas; Maylett Uzcátegui; Ricardo Picón; Scarlet Karina Montilla Barrios
La necesidad de crear nuevos sistemas constructivos en base a madera para viviendas, surge al considerar las pocas alternativas existentes en paises en desarrollo que garanticen una construccion economica, masiva y fundamentalmente sostenible. En este sentido, la presente investigacion pretende hacer un aporte para la implementacion de nuevos elementos estructurales para la construccion sostenible de viviendas de madera, que puedan ser fabricados mediante procesos de baja tecnologia, permitiendo un facil uso y apropiacion por parte de la poblacion en general. Especificamente se trata de un estudio sobre el desempeno de elementos tensados de madera, utilizados como componentes estructurales para viviendas. Para alcanzar los objetivos del proyecto se plantea el diseno de los elementos a partir del estudio de antecedentes y requerimientos contextuales, luego se procede a la validacion constructiva y estructural de los mismos a traves de la fabricacion de prototipos y de ensayos experimentales.
Structural system based on tensioned wood panels: experimental and numerical validation
(PGDesign/UFRGS, 2021) Scarlet Karina Montilla Barrios; Ricardo Picón; Mauricio Vargas; Maylett Uzcátegui
Housing in modern societies is a priority need. In the countries of industrial development, there are very sharp contrasts with respect to the housing deficit, affecting the great majority of the families with lower economic resources that solve their problem through subhuman constructions, elaborated, mostly, with residues of construction and disassembly of old buildings, highlighting the importance of the economy, from the financial point of the house built on the architectural quality and comfort. The need to create new building systems based on wood for homes arises when considering the few existing alternatives in developing countries that guarantee an economic, massive and fundamentally sustainable construction. In this sense, this research aims to make a contribution to the implementation of new structural elements for the sustainable construction of wooden houses, which can be manufactured by low technology processes, allowing easy use and appropriation by the general population. The system is called TENSO-WOOD, which is conceived as a system of solid wood plates of Caribbean pine, developed by means of low technology processes that allow an easy appropriation by the population in general. This paper presents a frame structural system using tensioned wood panels as structural elements. It is a lightweight prefabrication system for the construction of two-storey wooden houses. The system consists of bolted wood elements, creating different structural panels such as beam and column. An experimental program was carried out, which allowed knowing the mechanical behavior of each panel of the frame structure. In addition, it permits to know their maximum stress and deformations. The numerical models were compared with the experimental tests to validate and calibrate some parameters in the simulations. Therefore, the numerical models can be able to compute the load capacity and deformation of the wooden elements, obtaining behavior curves.
