Optimum range of slenderness ratio of hollow steel square braces for special concentrically braced frames

What is it about?

Choosing a proper steel brace in design process is an important parameter to make the project more cost-efficient. This study provides a simple criteria to choose an efficient brace section in order to delay the local buckling as well as complete fracture in the event of earthquakes.
