Evaluation of effect flexotorsor at talls buildings with the utilization of method of distribution of horizontals forces: modified PPG

Abstract

Presented of illustrated form the application of the method of distribution of horizontal:PPG modified. The method is applied at a building of six levels, whose lateral stabilizers are integrated for shear walls and frames distributed in plant of asymmetric form. The shear walls are from rectangular section and section canal, so that this building proves to be sufficiently simple in its structural conception. This makes possible that the analysis of the distribution of lateral forces may take effect utilizing the models and the methodology of calculation of the mentioned method. At a later time establish its numerical results of the plane and space behaviour of stabilizers in terms of forces and displacements, to evaluating the influence of the effect of the moment flexotorsor in the shear walls of section canal. Finally compare these results with the obtained ones belonging to space analysis of the building utilizing the method of the finite elements supported by the computer midways, becoming established the advantages of the method modified PPG.
