Sekundarni naslov:	Ductility of concentric braces
Sekundarni povzetek:	This graduation thesis describes the results of numerical simulations of concentrically braced frames, which were performed as preliminary estimation for experiments that will be carried out in the future. Numerical simulations were performed with Abaqus software. Nonlinear analysis included geometrical as well as material nonlinearity. The main purpose of this graduation thesis was to present an assessment of the behaviour of concetrically braced frames, with special concern in compresion members. Almost 100 nonlinear analysis were performed, which included monotonic loading of the frame and 6 analysis with cyclic loading. The main parameters, which vary in the analysis, were the end conditions of the braces (rigid or pinned), slenderness of elements and the shape of the cross-section of the braces. There were six angle (L-shaped), five channel (U-shaped) and 5 SHS cross-sections used in the analysis. The influence of this parameters on the brace buckling strength, post-buckling resistance and the damage on compression brace was examined. To determine the damage on compression members, we used two parametrs: the maximum in-plane and out-of-plane deformations of compression brace and maximum plastic strains, which developed in the comperssion brace during loading. Comparison between numerical results and values, determined by SIST EN 1993-1-1 and by AISC recommendations was also performed.
