摘要：The realistic degradation mode of the reinforced concrete (RC) frame structures can be verified through specialized theoretical and analytical studies. Thus, it was tried to demonstrate through this analytical research, the real mechanisms of seismic energy dissipation for RC moment-resisting frame systems with RC longitudinal rigid beams. In these conditions, it was studied the seismic response of a three GF 1F RC moment-resisting frame models (for three different concrete strength class and identical longitudinal and transverse reinforcements of structural elements) using nonlinear static analysis with ATENA software. Thus, it were specified important conclusions regarding the influence of the concrete strength class on the seismic degradation and collapse mechanisms for this type of structure (with rigid RC longitudinal beams). Also, it were observed the reinforcement insufficiencies in the vertical structural elements (RC columns) associated with the formation of plastic hinges.
