Abstract

The elastic and inelastic seismic response of 3, 9, 17 and 25 levels of reinforced concrete buildings (offices), located in the soft soil of Mexico City, with normal resistance concrete (f´c= 250 kg/cm2) and with high resistance concrete (f´c= 700 kg/cm2) are compared. The design with normal and high resistance concrete is made with the RDF-93 and RDF-04 codes respectively. The design results (transversal sections dimensions, vibration periods, lateral displacements, reinforcement steel, etc) are compared, after making a spectral modal dynamic analysis, as well as the non-linear responses (lateral displacements, global and local ductility demands, global distribution of plastic hinges, etc) from the step-by-step dynamic analysis with the SCT-EW record of the 1985 earthquakes. 1 Introduction The elastic and inelastic behavior of 3, 9, 17 and 25 levels reinforced concrete buildings (offices) is compared; it is designed with the RDF-93 Code [1] for normal resistance concretes and with the RDF-2004 Code [2] for high resistance concretes. The service (the ratios of relative lateral displacement do not exceed of 0.012 times the story high) and failure (given resistances to satisfy the seismic behavior factor Q= 3 requirements) limit states are satisfied according to the Complementary Techniques Norms in both Codes. The structures are designed
