The authors offer a methodology of allowable damage level assessment of concrete frame constructions under seismic loading represented by the earthquake accelerogram. Non-linear dynamic computations of the frames are carried out, taking into account cracking in reinforced concrete and reinforcement yielding. Computations are made by means of the software MIDAS/CIVIL program complex. The methodology opportunities are demonstrated on the example of the plane frame earthquake response computation. It is shown that bending moments dependences as functions of cross-sections rotation angles correlate to the Prandtl diagrams. The obtained value of the allowable damage coefficient is higher than the values recommended by the normative documents.
