Exploring the Feasibility of Infilled-Timber Frames in Seismic Regions Through Historical Vernacular Approaches

This paper presents a design proposal for a new two-storey residential building situated in the seismically active Italian region of Calabria. The design employs the traditional “baraccata” technique, originating from the same region and with historical roots dating back to the 18th century. This construction approach consists of a timber framework comprising vertical and horizontal elements with an infill of rubble stone masonry, resulting in walls approximately 300 mm thick. The seismic performance of the proposed structure has been evaluated through both linear dynamic and nonlinear static analyses conducted using SAP2000 software. Furthermore, it includes a calculation of the structure's embodied carbon, offering insights into its environmental impact. The findings suggest that the baraccata technique exhibits promising seismic performance, but further investigation is necessary to review detailing and prevent potential deterioration. Additionally, the study highlights the potential sustainability benefits of the method, particularly if reclaimed materials are used for the rubble stone masonry infill. This paper thus presents the baraccata technique as a prospective and sustainable option for new housing, contingent on further research.
