Abstract
Concrete structures built throughout the 20th century show performance deficiencies that lead to undergo seismic and energy comfort consequences. In particular, independent reinforced concrete (RC) structures do not comply with European energy efficiency standards due to the absence or insufficient insulation, or the existence of significant thermal bridges. Moreover, they were built with obsoleted construction methodologies that, being incompatible with actual structural canons, make them vulnerable to earthquakes. The current prefabricated technologies, used for the refurbishment of buildings, are focused on energy retrofitting, leaving the field of structural reinforcement unexplored. The challenge of this research is to improve and monitor the mechanical characteristics of RC buildings as well as their energy performance through precast concrete modules. In this paper, preliminary design strategies of the innovative panel is presented. It connects the existing façades, stiffening the pillar-beam nodes in order to obtain a box-like effect. Integration with real-time detection sensors ensures monitoring of energy and structural performance.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
