RESUMO:

This research consisted on the evaluation of the effects caused by the construction
sequence and the soil-structure interaction (ISE) in structural masonry buildings up
transition structures in reinforced concrete. For this, it was used the equivalent frame
model, developed by Nascimento et al. (2014), to simulate the interaction between the
structural walls in the first floor of the buildings and the support structure in reinforced
concrete, and the three-dimensional frame model, studied by Nascimento Neto (1999),
to simulate the structural walls in the upper floors of building. The analyzes related to
the construction sequence consisted of the gradual load and stiffness incorporation
during the construction time; while those related to ISE incorporated the effects of the
foundations deformability on the stresses distribution in the structure. Four modeling
methodologies were developed for two buildings with different geometries, and the
analyzes consisted on the evaluation of the stresses and displacements of the transition
structure (columns and beams), as well as the stresses distribution at the base of the
walls, for panels with different types of opening. The results show that the introduction
of the ISE and the construction sequence do not affect the stresses routing to the
supports, but their intensities, provoking relief or possible need for reinforcement in
elements exceed the safety limit, dimensioned in ELU. Besides that, it was confirmed
that the interaction with the soil reduces the differential settlements of the foundations.
