MORA, Mauricio Alexander; VILLALBA, Jesús Daniel  and  MALDONADO, Esperanza. Deficiencias, limitaciones, ventajas y desventajas de las metodologías de análisis sísmico no lineal. Rev. ing. univ. Medellin [online]. 2006, vol.5, n.9, pp.59-74. ISSN 1692-3324.

This research presents the comparison of different non linear analysis methodologies: the non linear response history analysis, the traditional pushover methodology, and two modal pushover methodologies. A medium rise reinforced concrete building, with moment resisting space frame, representative of the typical buildings in Bucaramanga, is examined using one of the earthquakes in the microzonation study of the city, which was scaled to different values of effective peak acceleration. The comparison of the results (floor displacements and interstory drifts) permitted to find deficiencies, limitations, advantages and disadvantages of the methodologies used. It was found that Modal Methodologies are a good approach to assess the seismic performance of reinforced concrete buildings

Keywords : análisis sísmico inelástico; análisis dinámico cronológico no lineal; análisis estático no lineal; pushover tradicional; pushover modal.
