Innovative and Sustainable Composite Material for the Seismic and Energetic Upgrade of Historic Masonry Buildings
نویسندگان
چکیده
Usually, energy and structural improvements for historic masonry buildings are addressed separately using distinct methods protocols. This paper covers an integrated assessment of new composite materials to reduce the seismic vulnerability while complying with sustainable conservation requirements, emissions’ reduction, savings. Firstly, this study focused on selecting suitable thermal mortars that could serve as base material innovative composite. Subsequently, mechanical characteristics these were examined by subjecting them compressive three-point bending tests. Dynamic thermo-hygrometric simulations conducted commercially available software check performance when used walls existing buildings. The mortar exhibited most favorable properties was subsequently reinforced a basalt fabric. A sample assembled subjected direct tensile testing determine its stress–strain behavior.

Seismic Mitigation of a Historic Masonry Building
This work presents an analysis of different proposals of rehabilitation of a masonry building, built around the beginning of the XX century for public schools, in the highest seismic risk zone of Argentine; and which was closed down after Mendoza`s Earthquake in 1985. The building has masonry walls of artisanal ceramic bricks and wood-framed roof but it does not have lateral ties. Currently, it...
متن کاملUncertainty in Seismic Capacity of Masonry Buildings
Seismic assessment of masonry structures is plagued by both inherent randomness and model uncertainty. The former is referred to as aleatory uncertainty, the latter as epistemic uncertainty because it depends on the knowledge level. Pioneering studies on reinforced concrete buildings have revealed a significant influence of modeling parameters on seismic vulnerability. However, confidence in me...
متن کاملSimplified indexes for the seismic vulnerability of ancient masonry buildings
This paper presents a contribution for the safety assessment of historical masonry buildings under seismic loading. Three different simplified safety indexes (in-plan area ratio, area to weight ratio and base shear ratio) are analyzed, taking into account a large sample of fifty-eight Portuguese churches. The sample of building has been organized according to the seismic zonation, from high to ...
