Using applicable and compatible earthquake and reinforced concretecodes, results were obtained and compared.The comparison results range from the consideration of seismic forces to the quantities ofsteel reinforcement required to strengthen the structural elements by examining their impactper square meter.In this study, CYPECAD, a software program from CYPE Ingenieros (http://www.cype.com),was used as a tool for calculating the seismic response of the structure according to theseismic codes from a selection of countries in Europe, Northern Africa, and South and CentralAmerica.It was concluded that the seismic action depends heavily on the definition of the spectrum andthe variability of the seismic factors considered according to each code, and that the Americancodes are more restrictive in terms of reinforcement requirements than the European codes.Furthermore, it was demonstrated that CYPECAD serves as an effective and powerful tool inobtaining results for the seismic analysis and design of structures.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 230
