Varying and alternating axial forces, compressive or tensional ones, can be appeared in Reinforced Concrete (RC) framed structures when they are subjected to seismic excitations. This especially holds for highway overcrossings under transverse horizontal or vertical seismic excitations, and especially for two-column framed-piers (bents) of RC bridges. The influence of such alternating axial forces on the behavior of RC shear-critical framed structures, ether bare or seismically strengthened by tension-tie elements, is investigated experimentally and computationally. For this purpose, a specimen of a two-columns one-story RC frame subjected to a recycling loading simulating seismic excitation is investigated. The relevant results show that the effects of alternating axial forces, and especially of tensional ones, can reduce the shear capacity of columns and be very important for the seismic behavior of RC framed structures and bridge-bents.
Promenljive i naizmenične aksijalne sile, pritisne ili zatezne, mogu se pojaviti u armiranobetonskim (RC) okvirnim konstrukcijama kada su izložene seizmičkim pobudama. Ovo posebno važi za prelaze autoputa pod poprečnim horizontalnim ili vertikalnim seizmičkim pobudama, a posebno za dvostubne uokvirene stubove AB mostova. Eksperimentalno i računski je istražen uticaj ovakvih naizmeničnih aksijalnih sila na ponašanje ramovskih AB konstrukcija sa kritičnim smicanjem, osnovnih ili seizmički ojačanih zateznim elementima. U tu svrhu istražuje se uzorak dvostubnog jednospratnog AB okvira podvrgnutog cikličnom opterećenju koje simulira seizmičku pobudu. Rezultati pokazuju da efekti naizmeničnih aksijalnih sila, a posebno zateznih, mogu da smanje smičući kapacitet stubova i da budu veoma važni za seizmičko ponašanje AB konstrukcija i mostova.
