Sažetak

Svrha ovog rada jeste da se prenesu i podele iskustva iz primene Evrokoda 8 (EN 1998). Sledeći postojeći okvir Evropskih standarda, razvijena su dva inženjerska pravca delovanja, tj. dve zasebne oblasti rada. Prva se odnosi na modliranje seizmičkih dejstava sa ciljem uzimanja u obzir njihove prostorne promenljivosti. Provereno je i dokazano da uključenje rotacionih komponenti može da utiče na efekte od dejstava i da rezultati dovedu do nesigurnih projektnih rešenja. Procena je izvršena korišćenjem metode spektra odgovora. U drugoj oblasti izučava se upotreba metode projektovanja na bazi seizmičkih performansi kao sredstva provere i potvrde za seizmičkim pojačanjima kao i potvrde njihove efikasnosti. Da bi se ovo uradilo, upoređeni su spektar ciljanog kapaciteta i stvarni spektar kapaciteta. Slučaj nedovoljne elastične krutosti i nedovoljne čvrstoće pri tečenju smatra se najtipičnijim seizmičkim slučajem kada je potrebno izvesti pojačavanja. Diskutovane su obe ove teme i formulisani su zaključci koji se odnose na filozofiju Evropskih standarda.

Ključne reči

Projektovanje seizmički otpornih konstrukcija prema Evrokodu 8 (EN 1998); uzimanje u obzir prostornu promenljivost seizmičkih dejstava; seizmičko projektovanje zasnovano na performansama
