Abstract (EN): A parametric study on the use of base isolation devices in frame building structures is undertaken. Frames were analysed with regular geometry starting from a baseframe (BF), from which more complex frames were created by association of BF in height above a certain asymmetric plant. The modularity of the BF facilitates the analysis of the results, allowing for parametric studies on the use of base isolation devices in more complex geometries. To conduct the computational studies the commercial software SAP2000 was used. Three-dimensional (3D) structures were analyzed with asymmetries in plant and in elevation. Some of the results of the parametric study are presented graphically, identifying the importance of positioning the seismic isolation devices used in each structural configuration. © 2006 Civil-Comp Press.
