BEAM DESIGN OF COMPOSITE BEAM AND SLAB SECTIONS FOR SAGGING AND HOGGING MOMENTS DESIGN | X01
Various deck layouts are possible: 1. No deck 2. Flat deck 3. Ribbed parallel to beam
4. Ribbed perpendicular to beam 5. Corrugated parallel to beam 6. Corrugated perpendicular to beam
The module reads sections from the PROKON® Section Database which contains the steel sections used in most countries.
Theory used in this module The module calculates the sagging and hogging resistance of composite beam sections according to rigid-plastic theory in Section 6 of EN 1994-1-1:2004 (Eurocode 4). It can evaluate both full shear connection and partial shear connection designs using plastic theory. The module verifies that the section is either a Class 1 or a Class 2 section as required for rigid-plastic theory design. It accounts for longitudinal reinforcement in compression (if present) for sagging resistance with the assumption that such reinforcement is fully anchored. To calculate the plastic bending resistance of the section, the module determines the plastic neutral axis (PNA) location of the section. It does this by balancing the contributing horizontal forces (based on plastic stresses) in the composite cross- section. In the shear connection calculations, the module checks headed studs for adherence to the ductility requirements for steel sections with equal flanges. It also checks resistance to vertical shear.
