Abstract: Calculations of bending moments on columns of 4 storey cast-in-situ flat plate system building with diaphragms considering seismic action are presented. To consider that action, different coefficients of allowable damages in calculations are submitted. The investigation results are shown, that in case of seismic load the general bending moment values on columns in compare with static load are exceed about 60…80 %. In case of seismic load, the difference between general bending moment values on columns depending on 0,4, 0,7 and 1,0 coefficients of allowable damages are approximately 25…50 %.

Keywords: reinforced concrete structures, flat plate, seismic action, coefficients of allowable damages, finite element method.
