Abstract
ABSTRACT: Wall-beam interaction (wall-beam system) is a phenomenon that requires further investigation in order to be consistently incorporated into structural building analysis. Researchers such as Wood, Rosenhaupt, Burhouse, Stafford Smith, Navaratnarajah, Davies, Riddington and Armed conducted tests on specimens to develop simplified analysis models, emphasizing the behavior of walls without openings under one span beams. The present study performed computational analysis using an specific equivalent frame model in order to study the behavior of the wall-beam system in more complex wall and beam arrangements. The examples considered the linear elastic behavior of materials and consisted of assessing stress distribution and displacements on support beams, in addition to stresses at the bottom of the walls, for panels in a real structural masonry building. Two- and three-dimensional analyses were used and the results showed the importance of three-dimensional analysis of wall interconnections. The effects of eccentricity between the vertical plane of the wall and horizontal support beam axis were also evaluated, showing the strong influence of twisting moments in support beam design.
Highlights
Structural masonry is a widely used system in the Brazilian construction industry, new studies are needed to enhance knowledge of its structural behavior
This study proposes using the equivalent frame model described by Nascimento et al [4], considering the calibrations developed by Medeiros [5] and Lopes [13], in order to analyze different configurations of the wall-beam system in a real structural masonry building
The present study consisted of analyzing stress distribution in the structural walls of masonry buildings over a transition structure of reinforced concrete
Summary
Structural masonry is a widely used system in the Brazilian construction industry, new studies are needed to enhance knowledge of its structural behavior. Paes [2] reported that this effect is relevant when the interaction between the masonry wall and its support structure is analyzed This behavior influences vertical load transfer, resulting in some of the load at the center of the beam traveling to the supports as an arch (Figure 1). The internal forces of the beam, especially the bending moments, tend to decline, with stress concentration at the extremities of the walls and normal vertical tensile stress in the central part of the deep beam (Figure 1). Silva [6] states that typical structural masonry buildings normally have a ceiling height of 2.80 m, requiring spans of more than 4.0 m to compensate for the abovementioned behavior In this case, studies using numerical modeling of only one ceiling height is sufficient to assess the phenomenon and its consequences in terms of beam forces and wall stresses
