Oscilacije konstrukcije sa pasivnim prigušivačima frakcionog tipa i suvim trenjem pri seizmičkom dejstvu / Seismic response of a column like structure with both fractional and dry friction type of dissipation

Description

<p>Proučeno je oscilatorno kretanje i disipacija energije stuba napravljenog<br />od nekoliko krutih blokova, koji pri horizontalnom seizmičkom dejstvu<br />mogu da klize jedan po drugom. Pored međusobnog kontakta sa trenjem, koje je<br />modelirano neglatkom viševrednosnom funkcijom, veze između blokova<br />sadrže i viskoelastične elemente, čije konstitutivne relacije uključuju<br />frakcione izvode, kao i ograničenja na koeficijente koja slede iz<br />Klauzius-Dijemove nejednakosti. Postavljeni Košijev problem predstavlja<br />uopštenje klasičnog problema ponašanja konstrukcija pod dejstvom<br />seizmičkog opterećenja, jer objedinjuje izvode proizvoljnog realnog reda<br />sa teorijom neglatkih viševrednosnih funkcija. Predložena je numerička<br />procedura za rešavanje postavljenog problema.</p> / <p> Seismic response and energy dissipation of a column made of several rigid<br /> blocks, which can slide along each other, was considered. Besides friction<br /> contact, which was modeled by a set valued function, viscoelastic elements<br /> whose constitutive equations include fractional derivatives as well as restrictions<br /> on the coefficients that follow from Clausius-Duhem inequality are present in<br /> connections between blocks. The posed Caushy problem represents the<br /> generalization of a classical problem of seismic response because it merges<br /> fractional derivatives with the theory of set valued functions. The numerical<br /> procedure for solving the problem was suggested.</p>
