Retrofit Strategies against Progressive Collapse of Steel Gravity Frames

Retrofit Strategies against Progressive Collapse of Steel Gravity Frames

Two retrofit strategies, aiming at increasing the collapse resistance of simple connections by adding seat angles and steel plates with long-slotted holes, are proposed in order to address the vulnerability of steel gravity frames under column loss scenarios. A high-fidelity, detailed, finite elemen...
