Effect of Over-Stroke Capacity of Curved Surface Sliders on the Collapse Safety of Seismically Isolated Buildings

RETROFITTING OF R.C. FRAME BUILDINGS WITH DOUBLE CONCAVE CURVED SURFACE ISOLATOR SLIDERS CHARACTERIZED BY OVER-STROKE DISPLACEMENT CAPACITY

Base isolation system is one of the most widespread passive control system techniques currently used for seismic protection of buildings and bridges. At the ultimate limit state, isolating devices are designed to attain the design displacement at the Maximum Credible Earthquake (MCE), while the superstructure remains in the elastic range for earthquake intensity corresponding to the Design Basis Earthquake (DBE). Among various isolation devices the friction pendulum sliders and elastomeric b...

Per una nuova cittadinanza digitale tra nuove competenze, metaverso, merito e inclusione

Questo lavoro rappresenta una prima ipotesi di ricerca sull’impatto del Metaverso in ambito educativo. Le nuove tecnologie e il digitale, dopo la Pandemia da Covid 19, hanno accelerato la nascita di un nuovo paradigma educativo nella scuola italiana. Didattica a distanza, didattica digitale integrata, intelligenza artificiale hanno pervaso in maniera significativa le nostre aule scolastiche ponendo al centro della riflessione scientifica un nuovo modo di fare scuola. La competenza digitale di...

LA PERICOLOSITÀ GEOMORFOLOGICA LEGATA AL RUSCELLAMENTO SUPERFICIALE NELLA CITTÀ DI MATERA TRA COMMISTIONE DI FORME URBANE E FORME DEL PAESAGGIO FISICO

The Matera town is located on a plateau made of Mesozoic limestone covered by a Pleistocene bioclastic calcarenite, moderately cemented and easily mouldable, as shown by the presence of the well-known cave-houses of the Sassi area. Water management has always been a central issue throughout the history of the city: for millennia, urban development has guaranteed the balance between humans and environment. Climate changes coupled to anthropic interventions sharply compromised such a relationship.
