چکیده:

Achieving specified performance targets in different seismic levels, have always been an earthquake engineering issues. most of existing standards, based on force-based design method. This method’s short comes and disadvantages have led researchers to explore and develop new techniques. Displacement-based design is one of the last tools for performance-based design method. Instead of limit the structure, this method tries to design it for specified performance seismic levels. In this study, EBF steel frames with medium hight (8, 10, 12 stories) were design with two direct displacement-based design and force-based design (accordance with the 3rd versoin of Iranians cod of practice for seismic resistant design of buildings, standard No-2800) methods. In order to evaluate this structures behavior and comparsion two methods, these frames were analyzed with one group real scaled accelorogram, by dynamic nonlinear time history (Each group of accelerogram has 7 records). Results show that, frames which design with direct displacement-based design is greatly near to it’s objective performance which is limited drift ratio to 2%. While designed structures with force-based design method that was controlled with 2800 driftratio limited, don’t provide it’s objective performance.
