| Resumo: | The developed study proposes a new computer modeling efficient and easy to apply
in usual project situations to evaluate the interaction between masonry panels and
support structure. The proposed model simulates the behavior of the wall exclusively
using frame finite elements, thus compounding an equivalent frame. The validation
was performed in two ways: firstly, through the analysis of various panels of generic
plans, comparing the results obtained from equivalent frame model with the ones
from a reference model, which uses shell finite elements in discretization of the walls;
and in a second step, comparing with the results of the experimental model of
Rosenhaupt. The analyzes considered the linear elastic behavior for materials and
consisted basically in the evaluation of vertical displacements and efforts in support
beams, and tensions at the base of walls. Was also evaluated, from flat and threedimensional
modeling of some walls from a real project, important aspects of the
wall-beam interaction, e.g.: the presence of openings of doors and windows,
arranged in any position; conditions of support and linking of beams; interference of
moorings between walls; and consideration of wind action. The analysis of the
achieved results demonstrated the efficiency of the proposed modeling, since they
have very similar aspects in the distribution of stresses and efforts, always with
intensities slightly larger than those of the reference and experimental models. |
