Un approccio numerico allo studio del moto ondoso all'interno di barriere frangiflutti virtuali e della stabilità della mantellata
(Universita degli studi di Salerno, 2015-04-15)La presente tesi di dottorato intende presentare i risultati della validazione di una procedura numerica innovativa per la simulazione dell'interazione tra il moto ondoso e le barriere frangiflutti emerse. Prima di entrare ... -
Numerical modeling of traces in gravel-bed rivers
(Universita degli studi di Salerno, 2015-04-26)The erosion, transport and deposition of pebbles in rivers have often been studied by considering the motion of tracer particles. There are reports of bedload tracing programs in field and laboratory since the late 1930s. ... -
Studio dell'interazione tra moto ondoso e strutture marittime mediante modellazione fisica
(Universita degli studi di Salerno, 2015-04-27)Le aree costiere rappresentano sistemi naturali del tutto unici, così come unici sono i fenomeni che le caratterizzano. L’erosione dei litorali, divenuta ormai un fenomeno di interesse planetario, ha spinto verso ... -
Influenza del comportamento ciclico dei collegamenti trave-colonna sulla risposta sismica di telai in acciaio regolari o in presenza di "set-backs"
(Universita degli studi di Salerno, 2015-04-28)In accordo con i criteri della progettazione sismica tradizionale, la dissipazione dell’energia sismica in ingresso nei telai sismo-resistenti avviene in alcune zone degli elementi strutturali che vengono impegnate in campo ... -
