Joint Geometry Data: (+ve Tension, - Ve Compression)

This document provides geometry data and analysis of the forces and strengths of a T-shaped steel joint with a chord section of 200x200x8 mm and a brace section of 100x200x8 mm. Key details include: the chord can resist 219,404 N of axial force through chord wall plastification; the joint's in-plane flexural strength is 242,123,373 N-mm governed by chord wall plastification; and the out-of-plane flexural strength is 146,864,39 N-mm also governed by chord wall plastification. The utilization ratio of the joint is calculated to be 1.89, validating its design.
