Initially, the system was simple but as the time passed, due to shortcomings and economical problems, the type of braces changed and the changes were followed by its own complexion and complications. With better understanding of behavior and performance of the simple braces, the uses of these increased, but buckling was most problems in the braces. In 1973, buckling resisting braces (BRB) were introduced. In this version of braces, a steel tube prevents the buckling of axial members, which in turn leads to an increased in BRB forces. The aim of the present study was to investigate an all steel BRB with specific detailing in order to produce a uniform plastic region. Its advantages of use of this BRB are being lighter, ease of construction, core opening re-evaluation possibility after loading and use of single material.... To do so, some experimental processes on six specimens with 1:4 scales were made. The results indicated that if the required details are observed the brace would have proper behavior and high-energy absorption.
