Types of concentric structural braces


Braced frames may be grouped into two categories as either concentric braced frames (CBF) or eccentric braced frames (EBFs). In CBFs, the axes of all members, that is, columns, beams, and braces intersect at a common point such that the member forces are axial without signifcant moments. 
On the other hand, EBFs, utilize axis offsets to deliberately introduce flexure and shear in preselected beam segments to increase ductility. Braced frames can take on many configurations some of which are shown in the figure. 

The diagonal member often consists of double angles, channels, tees, tubes or wide flange shapes, their selection frequently based on the ease of connection details.click here to continue read
