Survey upon the Seismic Resistance of RC Structures

*Technical University of Cluj-Napoca, Civil Engineering Faculty

The paper presents results and conclusions of more than a decade of investigations concerning the safety against earthquakes of buildings with RC structures in Romania. Investigations were done according to the evaluation procedure given by the Romanian code of practice for seismic evaluation. After a general introduction about the earthquakes threat for buildings and human life, the paper continues with the seismic activity background in Romania.

Next sections reveal general information about the evaluation procedures and methods used in buildings assessment. Results are presented in a synthetic manner for the different structural solutions considered, based on the nominal grade of safety against earthquakes and other factors considered.

The paper ends with conclusions and commentaries about seismic behavior and safety against earthquakes induced progressive collapse of common structural types.
