The investigation on the effect of using concentrically and eccentric brace in three dimensional steel frames with static pushover analysis method

In recent years, for the earthquakes that buildings can face, especially in designs made in earthquake zones or after the earthquake that has undergone to investigate the situation under their own loads the examination of the elastic behavior has gained great importance. Examination of the elastic behavior of systems under earthquake loads and the assessment reveals more meaningful results about the design. Earthquake performances of existing or new buildings can be easily determined. The first general information about static push-over analysis was given in this thesis study. Use of static push-over analysis in building systems has been to handle And the effect of cross use in 3D steel frame systems has been determined by the static-thrust analysis method. FEMA and ATC regulations have been utilized during these procedures. Different frame systems were selected and comparisons were made. Three-dimensional analysis of frame systems was made by utilizing the SAP 2000 program and the evaluations of the systems of static thrust analysis are given in the result section.
