WebNov 25, 2024 · The experiments demonstrated the superior performance of aluminum core BRB over steel core BRB. The experimental studies on the BRKB-TMF concluded that per the design intent, the BRB acted like a fuse for the frame by restricting all the inelastic deformations to itself and the study frame could successfully meet the target drift criteria. WebThe formula for the Euler buckling load is 10. (10.6) f c = − k π 2 E I L 2, where E is Young's modulus, I is the moment of inertia of the column cross-section, and L is column length. The value of k varies with the end conditions imposed on the column and is equal to the values given in Table 10.1. Table 10.1.
