Sažetak
U ovom radu provedena je analiza izvijanja konstrukcije pješačkog mosta primjenom metode konačnih elemenata. Formulacija uzima u obzir utjecaj velikih pomaka na konstrukciju pod utjecajem konzervativnih i statičkih vanjskih opterećenja. Materijal se pretpostavlja linearno elastičnim i izotropnim. Stabilnost analize provodi se na temelju vlastitih vrijednosti (eigenvalue). Linearizirane ravnotežne jednadžbe grednog konačnog elementa izvedene su primjenom principa virtualnih radova i nelinearnog polja pomaka poprečnog presjeka.Reference
