5 Conclusions
The complex set of experimental tests has been carried to check the behavior and
capacity of multilayered wall connections. The research was conducted for the
purpose of traditional large-panel residential buildings where the connections are the
most challenging in case of the definition of their strength. The tests were finished
with the preliminary simplified numerical calculations, which were useful as the
partial validation of the tests and showed potential future fields of studies. Analyzing
the obtained numerical simulation and comparing them with experimental research,
it can be concluded that the computed results are close in some cases and relatively
large in others. These differences can be caused by numerical model simplifications.
Cracking and cruising effects in concrete were not taken into account due to possible
computing consuming high nonlinearities, which could appear during calculations
for all the cases. The main aim was to build an overview estimation as the initial step.
A more detailed simulation would solve the differences in the results for the chosen
types of connections basing on calculations described here.
The most considerable differences were identified in the case of three-layer block
models with a 45° anchorage model. Differences appeared for cases with forces
