The use of different alternatives for construction also implies a correct analysis and design applying regulations and recommendations, in order to obtain seismic-resistant structures. The purpose of this research was to comparatively evaluate twelve structural models with different types of roofs (two, four and multiple waters), separated in Reinforced Concrete and Steel Framing. These models complied with the seismic-resistant parameters established in the NEC-SE-DS-2015. The results obtained were evaluated by means of analytical and comparative graphs that showed that Steel framing structures are significantly lighter with respect to reinforced concrete, finding a 94.1% reduction, which directly influences the dynamic and static shear. The Steel framing system has low ductility, but this does not mean that it is a material that does not resist seismic forces since it is a system of reduced mass and high stiffness due to the fact that diagonal bracing is placed in the wall panels, which allows the oscillations of an earthquake to be of high frequency in very low periods, concluding that the structures are adequate.
