Strong column weak beam design
WebThird, with the same fortification level, the design of joints should follow three principles: strong column - weak beam, strong shear - weak bending, and strong joints - weak components. So, structural components should have “capacity gradient”: some elements damage prior to others to ensure the performance of the overall structure [1] .

There are additional important considerations. The performance objective of the ductile coupled shear wall system is for the majority of energy dissipation to occur in the coupling beams. This is analogous to strong column …
WebJun 1, 2024 · This concept of postponing the column plastic hinging after the beams is known as the strong column-weak beam (SCWB) criterion. In the AISC, the SCWB criterion for SMFs is checked by dividing the flexural strengths of the columns to that of the beams at each joint, and this ratio must be greater than 1.0 for all joints.
