The diploma contains a comparative analysis of three different computer programs for
nonlinear seismic analysis of masonry buildings, restricted to modern buildings. Prototypes
or full scale buildings, as well as models or scaled buildings were subjected to the analysis.
The assessment of model structures was necessary for the analysis of effectiveness of each
software in the response estimation of model masonry buildings, tested on the shaking table.
For the purpose of design of model buildings, complete model similitude was taken into
account.
The diploma consists of a theoretical part, with an explanation of parts of standards that are
used for the calculation of the seismic resistance of new masonry buildings and on which
discussed programs are based (Sremb, 3Muri and AmQuake). A description of the simplified
method N2 is given as well as a short description of operation for all three programs. In the
computation phase, the particular buildings are analyzed. On the basis of the acquired
results, a comparison is made between the outputs of different programs. Finally, the
numerical results are compared to those gained from the experiment on the shaking table.
In the conclusion, based on acquired results, we can state that computer programs give
conservative results. Due to various applied simplifications, different levels of compliance of
standards and other factors, the numeric results often do not reflect the actual state. Despite
all, it is possible to make a good approximation of the actual response with simplified numeric
models that take into account the global response mechanism instead of the storey response
mechanism.
