Steel Structures Section of the Turkish Earthquake Code 2007 includes very important improvements. Especially, extensive modifications have been presented in the computation of link member's lengths in eccentric braced frame systems. Different values can be chosen for the lengths of the link members based on upper and lower limits using an equation given in the code. The aim of this study is to investigate the effect of various link member lengths on the lateral load capacity of eccentric steel braced frames in which the lengths are chosen in between upper and lower bounds specified in the code. Three-dimensional two-storey experimental steel frame systems were built using rectangular hollow cross sectioned V-bracings and inverted V-bracings. Then, these experimental systems were numerically analyzed using general purpose finite element software-SAP2000. The results obtained from experimental study and numerical analyses were evaluated on the basis of Turkish Earthquake Code 2007.
