Lateral load carrying capacities of reinforced concrete structures which are designed
by considering only gravity loads or according to outdated earthquake codes can be
insufficient. The most important problem for these buildings is the limited ductility
of the frame elements. How to evaluate the performance of an existing structure and
to what level to strengthen it had been major concerns for structural engineers.
Recent earthquakes which occurred in the Marmara Region in the last decade have
increased the number of seismic assessment projects drastically. However, there
was no special guideline or code dealing with the assessment of existing buildings.
In order to have uniformity in assessment projects, a new chapter has been included
in the revised Turkish Earthquake Code (2006).
In this study, the existing and retrofitted conditions of a reinforced concrete
building were assessed comparatively by employing linear and nonlinear
assessment procedures according to different seismic rehabilitation codes. The
study was carried out on a six storey reinforced concrete telephone exchange
building. Although there was no damage in the structure due to the recent
earthquakes that occurred in the Marmara Region, the building was assessed and
retrofitted in 2001 by using equivalent lateral load analysis results. The results of
linear and nonlinear assessment procedures performed in the scope of this thesis,
were also compared with the assessment results of this previous study.
In the nonlinear assessment procedures, pushover analysis results were used. In
addition to comparison of the assessment procedures, efficiency of a widely used
approximate pushover method was also investigated.
