Investigation of various modeling strategy in nonlinear analysis of concrete frames

The experimental tests on full-scale structure models assisted the calibration of numerical models and sustain in the assessment of proportioning and detailing rules for the different structural sub-assemblages. This complementary numerical and experimental approach emphasise the important role of the research for the mitigation of the seismic risk. In this study, 4-storey reinforced concrete frame structure is modelled with considering the nonlinear behaviour which is done pseudo-dynamic test. This full-scale RC frame representative of the building's design and construction practice until the late 1970's in most of south European countries, and currently needing seismic retrofit, were constructed and tested pseudo-dynamically, at the ELSA laboratory (European Laboratory for Structural Assessment). The test frame had been designed without specifically considering seismic action (non-seismic resistant constructions). In the first chapter; introducing the topic, revision of the studies on the subject with the purpose and scope of the study is situated. The second part describes the nonlinear behavior of structures and factors influencing this behavior. The third section describes the performance-based design and nonlinear analysis. In the fourth section contains information about the properties of reinforced concrete frame system that has been applied to pseudo-dynamic testing. In the fifth chapter, which provides information about the reinforced concrete frame modeling and nonlinear analysis results obtained by different modeling strategies from each other and to the comparison with the results obtained from experiments with these results. In the sixth chapter, the results obtained from the study are given advice on the subject interpreted.
