dc.description.abstractAnalysis of RC structures subjected to seismic loads vary greatly around the world, from simplified static models to more advanced methods, which take account of real dynamic loads and the nonlinear response of structures. As a recent theory, lumped damage mechanics apply the concepts of damage mechanics and the classic fracture in plastic hinges for nonlinear analysis of RC structures. Therefore, this research analysed the behaviour of RC dual system structures designed according to Brazilian Standards Codes, that did not consider the recommendations of NBR 15421, under seven real seismic loads, with magnitude units in Richter scale (ML). It was concluded that all structures regardless of structural system and number of storeys might suffer severe values of structural damage when subjected to earthquake magnitudes equal or greater than 5.0 ML. Besides that, even for earthquake magnitudes above 3.0 ML, in most of structures, the interstorey drift ratio was not in requirements with international standard codes, causing cracking in nonstructural elements and demanding higher repair costs.
