Loads Per Truss Beam (KN)

The document provides load values and material properties for structural analysis of a truss beam. It lists dead loads, live loads, and snow loads on the roof in kilonewtons (kN). It also gives load combinations factors and provides material characteristics like modulus of elasticity (Es), yield strength (fy), and section properties of an HEB 240 beam including moment of inertia (Io) and section area. Charts are shown for instability curves for column, frame and cold formed sections, as well as a proposed fire design.
