Abstract


A comparison is applied to a seismic analysis of a building of four levels with steel doing, despising and considering the deformations by sharp. Two models were developed: The model # 1 not deigns the deformations by sharp. The model # 2 considers the deformations by sharp. The modal analysis and spectral analysis of both models used software MATLAB. For the static analysis applied software COLIBRI for first and software DINAFACIL for the second, was taken into account this software indeed because they are become attached to such conditions already mentioned. As far as obtained results they were observed that the second is economic approximately 3% as far as the mechanical elements (Axial Forces, Forces Sharp and Flexionantes Moments) and in addition is the one that is become attached but to the reality
