Flange plate moment connections are a vital part of steel construction, providing a secure way to join beams, columns, or girders and transfer axial and moment loads between them. These connections are designed to withstand the stresses placed upon them, ensuring the overall structure can handle the load conditions. WebOct 19, 2024 · 1. The first approach uses the "Static Procedure". A torsional moment (Mz) is computed based on the seismic lateral story force obtained from RSA which is multiplied by the specified diaphragm eccentricity. The torsional moment is applied to all stories which have a diaphragm assignment (rigid or semi-rigid diaphragm). prochain sniper ghost warrior
