REINFORCED-CONCRETE WALLS

Armiranobetonski zidovi su kruti vertikalni elementi koji služe kao konzolni nosači. Imaju povoljan oblik u smislu geometrije i vrlo su djelotvorni pri prenošenju horizontalnih sila vjetra i sila od potresa. Uz horizontalne sile koje nastaju prenošenjem posmičnog naprezanja spojem međukatne konstrukcije i zida, postoje i vertikalna opterećenja. Zidovi su znatno manje kruti okomito na svoju ravninu. Prema obliku razlikujemo visoke i niske zidove, zidove i presjeka i perforirane armiranobetonske zidove. Takvi zidovi dijele se još obzirom na način armiranja te s obzirom na statički proračun. Niski zidovi su podložni utjecaju poprečnih sila dok su visoki zidovi podložniji utjecaju momenta savijanja. Zidovi I presjeka imaju veliku nosivost i uz povoljno armiranje, veliku duktilnost. U radu je dan pregled proračuna i armiranja ovdje opisanih vrsta zidova.Reinforced walls are rigid vertical elements which acts as cantilever bearing elements. They have good geometric shape and are very effective in transmitting horizontal wind and earthquake forces. Along with the horizontal forces generated by the transmission of shear stress at the joint between the floor bearing system and the wall, there are also vertical. The walls are considerably less rigid perpendicular to their plane. Depending on the shape, we distinguish high and low walls, with I cross section and perforated reinforced concrete walls. Such walls are differentiate by reinforcement and by static calculation. Low walls are more susceptible to influence of transverse forces then the bending moment. The walls with “I” cross section have a high load-bearing capacity and, with favorable reinforcement distribution, high ductility. This work gives an overview of reinforcing and calculation of here described wall
