Abstract

The performance of a BRBs is highly dependent on the geometric characteristics of sections. Steel core components play highly role in the absorption of energy and the other members only prevent buckling, Therefore the proper performance of BRBs are dependent on suitable steel core sections. There is an example of a recreant steel core of 40mm*20mm with total length of 2660mm selected in accordance to the Zsarnoczay Laboratory and modeled in the finite element software. Then compared with laboratory and accuracy results in the ABACUS SOFTWARE three other models of 40mm*30mm, 40mm*40mm, 60mm*20mm with overall length of 2660mm in accordance with the necessary invariant bracket factors taken from the Pedro Romero laboratory paper were introduced, modeled and verified with the same physical specification. Then the cross section of 40mm*30mm was selected as the appropriate cross section for the recreant steel core in terms of software output based on parameters such as hysteresis curve comparison, sample hardness comparisons, proper ratios of compressive force to tensile strength. Then for accuracy of suitable cross section for different model, by retaining the proportions of the bracing components, recreant core 40mm*40mm with a total length of 3600mm were modeled.
