Sažetak

U cilju evaluacije valjanosti vibracija kod konstrukcije pešačkih mostova većina konstruktora koji projektuju mostove koriste modele sila kod pešaka koje se određuju za hodanje po krutoj površini. Ovaj metod se više ne koristi za konstrukcije koje su vitke, lake i sa malim frekvencijama a koje su podložne primetnim vibracijama koje pobuđuje hodanje. U cilju prevazilaženja ovog problema neophodno je razumeti kako se pešak kreće i kakva je interakcija između procesa kretanja i konstrukcije koja vibrira. Ovaj rad prikazuje tri metode modelovanja kretanja pešaka po nestacionarnoj konstrukciji i vrši kritičku evaluaciju pogodnosti takvih konstrukcija za modelovanje mehanizma povratne sprege između konstrukcije i pešaka. Evaluacija modela je izvršena s obzirom na njihovu sposobnost da reprodukuju ljudsko kretanje kao i vibracije registrovane na nestacionarnim mostovima. Pokazano je da su modeli koji se koriste u biomehanici pogodni za primenu u kontekstu konstrukcija.
