Reference BS 449 Part 2: Design of Moment Connection Flush End Plate Moment Connection

This document provides details for designing a flush end plate moment connection, including section dimensions, straining actions, material properties, number and placement of bolts, and calculations for welding size and end plate thickness. Bolt sizes, grades, forces, and utilization coefficients are considered. Allowable weld stresses and electrode specifications are referenced. Calculations are shown for tension in the flange, minimum weld size, and thickness of the end plate based on the pitch and placement of bolts.
