abstract = {The requirements for modern brick masonry have grown
steadily in the past. In addition to the architectural
requirements for user flexibility and aesthetics, they must
also be optimally designed in terms of the structure,
energy, sound insulation and fire protection. The complex
combination of the above-mentioned criteria often leads to
the fact that the structural design of buildings made of
brick masonry is only possible with great effort or with a
hybrid construction method. Conservative linear design
methods prove to be incapable of exploiting the available
load-bearing reserves. The solution appears to be the
application of modern nonlinear deformation-based
verification methods. Although these methods provide a more
realistic representation of the load-bearing behavior of
masonry, they also impose increased requirements on the
calculation model and the masonry-specific design
principles. In practice, the design principles are
criticized, among other things, because of the very
simplified modeling assumptions and the resulting inadequate
representation of the interaction effects within the
building structure when determining the internal forces.
Moreover, the application of the design concept according to
DIN EN 1996-1 in connection with the validity of the shear
failure criteria is to be questioned. Furthermore, important
details of the structure, such as the reduced slab support
at the energy-optimized wall-slab node, have not yet been
considered in the codes. The exploitation of existing
load-bearing capacities by modifying masonry-specific rules
is of essential importance for the future viability of
masonry as a building material. The present work
investigates the load-bearing and displacement behavior of
unreinforced brick masonry with special attention to the
influence of wall-building interaction. For the
investigation, a nonlinear three-dimensional micromodel is
developed, which can represent effects in the wall plane as
well as out of the wall plane. With the help of the
numerical model, a comprehensive variant study is carried
out, considering all the main parameters influencing the
shear-bearing behavior. The consideration of a variable
moment distribution over the wall height as well as an
eccentric vertical load introduction due to partial slab
support at the wall head is of particular importance. To
investigate and differentiate the decisive failure
mechanisms at wall level, the stress and strain states at
both joint and individual brick level are analyzed, and the
capacity curves are evaluated with respect to load-bearing
and displacement capacity. Next, the obtained knowledge will
be used and incorporated into an improved design approach,
which should enable the correct representation of the
horizontal load-bearing capacity with a simultaneously
manageable computational effort for the practical
application in construction. Finally, the development of a
macromodel for the simulation of masonry shear walls with
and without eccentric vertical load introduction at the wall
head is described.},
