Reinforced concrete structures used in many areas of our daily life
constitute an important part of the building stock in the construction sector.
There are many buildings such as reinforced concrete buildings, bridges,
tunnels, mosques and dams, and the construction of new buildings in line with
the need continues. Many uncertainty factors play a role in the design phase of
these structures from the dimensioning as a result of the analysis performed
under the required loadings to the implementation phase in the field. Many
unpredictable factors such as errors in the analysis, defects in materials and
workmanship affect the success rate of the project of the structure. For this purpose,
Experimental Modal Analysis method, which is widely used in the literature, is
used to determine the success rate of new structures, to determine the dynamic
characteristics and damage conditions of existing structures and structural
health monitoring. Natural frequencies, which are the dynamic variables of the
structure obtained by experimental modal analysis techniques, and mode shapes
and damping ratios corresponding to these frequencies are used in the
examination of the current state and structural properties of the structures.
However, this experimental data can be obtained by with foreign-source software
by allocating large budgets. The results of the native experimental modal
analysis and finite element model update software developed within the scope of
doctoral thesis are compared with the results of the existing software in the
literature. As the application, raw signal data of Gulburnu Bridge and scaled
Type-1 Arch Dam constructed in laboratory environment were used. The experimental
results of the developed software and the existing software were found to be
closely related to each other.
