Evaluación del Efecto Flexotorsor en Edificios Altos con la Utilización del Método de Distribución de Fuerzas Horizontales: PPG Modificado

摘要

The application of the distribution of horizontal forces method -Method PPG modified- is presented for a six-level building, whose lateral stabilizers are made up by sprandel walls and frames asymmetrically distributed on a ground plant sprandel walls have rectangular section and canal section, so that this building proves to be sufficiently simple in its structural conception. This makes it possible that the analysis of the lateral forces distribution may take effect by using the calculation methodology and models of the method already mentioned. Later, the numerical results of the plane and space behaviour of stabilizers in terms of forces and displacements are set, with the influence of the flexural-torsional moment effect on the canal section's sprandel wall being thus evaluated. Finally, these results are compared with those obtained from the space analysis made with the STAAD.pro2006 software, thus the advantages of the PPG modified method being set.
