Estudio Experimental De Cargas Sobre Muros Cartón Yeso (Drywall)

This research studies the Drywall panel's behavior subjected to the action of horizontal loads. Furthermore this pretends to establish a comparison between the damage produced in the two systems (Drywall - Masonry) when they were submitted to horizontal loads. The research gave as a result that Drywall panels submitted to drift values about 0.5% had an acceptable behavior from the point of view of the damage present in this system compared to masonry nonstructural walls. Being Drywall panels nonstructural walls with larger inter story drift capacity than masonry walls, they emerge as a new alternative because of the requirements presented in NSR-98 (Norma Colombiana de Diseño y Construcción Sismo Resistente) about demand of drift.

Industrial or traditional bamboo construction? Comparative life cycle assessment (LCA) of bamboo-based buildings

© 2018 by the authors. The past five decades have witnessed an unprecedented growth in population. This has led to an ever-growing housing demand. It has been proposed that the use of bio-based materials, and specifically bamboo, can help alleviate the housing demand in a sustainable manner. The present paper aims to assess the environmental impact caused by using four different construction materials (bamboo, brick, concrete hollow block, and engineered bamboo) in buildings. A comparative life cycle assessment (LCA) was carried out to measure the environmental impact of the different construction materials in the construction of single and multi-storey buildings. The LCA considered the extraction, production, transport, and use of the construction materials. The IPCC2013 evaluation method from the Intergovernmental Panel on Climate Change IPCC2013 was used for the calculations of CO2 emissions. The assessment was geographically located in Colombia, South America, and estimates the transport distances of the construction materials. The results show that transportation and reinforcing materials significantly contribute to the environmental impact, whereas the engineered bamboo construction system has the lowest environmental impact. The adoption of bamboo-based construction systems has a significant potential to support the regenerative development of regions where they could be used and might lead to long-lasting improvements to economies, environments, and livelihoods

Tras siglos de uso, la guadua se somete a pruebas científicas

Materiales innovadores: una apuesta de investigaciónDesde el 2007, el ingeniero Correal estudia la guadua en busca de suficientes explicaciones científicas de su comportamiento estructural. Ello permitirá difinir unos estándares unificados para promover la construcción sostenible de viviendas de hasta cuatro pisos. El modelo de casa construido con guadua laminada fue sometido a sismos de diversa intensidad apra probar la resistencia del material, medida con sensores que se colocaron en distintas partes de la estructur
