Item Analysis of Planar Double-Layer Timber Spatial Frames by Using Parametric Tools(2024-08) Manterola-Ubillos, Maddi; Gonzalez-Quintial, Francisco; Rico-Martinez, Jose Miguel; Benito Ayucar, Josu; Begiristain-Mitxelena, Jon Andoni; Materiales Construcción AzpeitiaIt is in the preliminary design phase of a project that the designer makes decisions concerning the global geometry of the structure. When working with space frames, the choice of the frame topology is key for the structural behavior. It is difficult to find manuals that provide guidance on which of the most common topologies is the right one for the project, let alone in wood construction. In response to this shortcoming, the use of parametric software is proposed (Grasshopper build1.0.0007 and Karamba 3D 2.2.0.16-220828). The aim is to create a dynamic catalog that responds instantaneously to changes in the parameters to provide information on structural behavior, pre-dimensioning and metrics. With the display of all this information, the architect will have enough technical argumentation to choose or reject options. The proposal is developed through a case study: the early design and analysis stages of flat double-layer timber spatial frames as for rectangular medium-span roofs.Item Full scale experimental performance assessment of a prefabricated timber panel for the energy retrofitting of multi-rise buildings(2017-09) Garay, Roberto; Benito Ayucar, Josu; Arregi Goikolea, Beñat; Garay Martinez, Roberto; Tecnalia Research & Innovation; Materiales Construcción Azpeitia; EDIFICACIÓN DE ENERGÍA POSITIVAA prefabricated timber façade system is presented for the energy retrofitting of buildings. Large panel dimensions facilitate the installation of this system, with reduced disturbance to building users and increased overall quality in terms of thermal bridge mitigation and air tightness of architectural junctions. A full scale proof of concept test is performed, where several prefabricated timber panels were installed over a pre-existing brick façade, their junctions tested, and the differential thermal performance of the system is evaluated. It is concluded that the overall thermal performance of the system is satisfactory in terms of overall U-value, thermal bridge coefficient and, temperature factor. Furthermore, and based on experimentally obtained data, a dynamic characterization of the harmonic thermal response of the system is performed.
