INFLUENCE OF PLAN IRREGULARITY OF BUILDINGS

This article shows an analytical description of the damages caused by different plan irregularities, during seismic events of different magnitudes. Although these effects of architectonic and/or structural configuration have been identified like not adapted in previous damages, have come maintaining their presence in constructions anywhere in the world. The effects of commented irregularities were studied with qualitative analyses of important and recent investigations, as much in Mexico as abroad. The work describes to the geometric forms that are repeated more in the urban areas in Mexico (squared, rectangular, section U, section L and section T), as well as its variations from plants observed with extracted aerial photography of Google Earth. These architectonic plants were modeled in SAP2000 considering one, two and four levels to determine the effect of the geometric form in the seismic behavior of structures with elastic analyses. Also, effects of the extension in rectangular plants and the inclusion of projections in sections with architectonic plants U, L and T were studied. In all the studied systems, effects of different irregularities are analyzed based on the variation of displacements, with respect to regular systems.
