Tipovi kapitela:
Pečurkaste ploče
Manja opterećenja Veća opterećenja
Metoda zamenjujućih okvira
• Metoda podrazumeva da ploča sa stubovima čini kontinualni okvir• U propisima mnogih zemalja• Široka primena (metoda traka)
Metoda zamenjujućih okvira
Računski rasponi i visine zamenjujućeg okvira, krutost rigle
Raspodela momenta po trakama na širini polja lx
Raspodela momenta po trakama na širini polja lx - DIN
Raspodela momenta po trakama na širini polja lx - BAB 87
Armiranje pečurkastih ploča
Armiranje kapitela:
Proračun na probijanje(ploča bez ili sa kapitelom)
Uticaj blizine otvora na probijanje:
Položaj armature za osiguranje od proboja
Kada je presek stuba pravougaonik, dimenzija b/d, onda se zamenjujući prečnikkružnog preseka sračunava kao
ds = 1.13√bd
Ako je d > 1.5b treba uzeti d=1.5b. Razlog za ovo je što se koncentracija smicanjadešava na uglovima, s jedne strane, a sa druge, na bočnim stranama stuba većedužine ne vlada dvoosno stanje napona pa su dopušteni naponi manji i taj deo sezanemaruje.
