1 Walls Wall Applications is a slender, efficient building element for wall constructions that demand a high level of both energy efficiency and strength. Using pre-insulated studs facilitates easy insulation of the structure and thereby contributes to overall cost savings.

2 for walls Characteristic axial compression loads for steicowall To EC Type SW SW 0 SW 90 Flange b * h [mm] With one side only sheathed a) N k [kn] With both sides sheathed a) N k [kn] *.. 0 * *.0.9 Note: The above tables are based on a wall panel height of, m. Sheathing to the requirements of BS 8 to provide lateral restraint to the flanges and it is recommended that in all construction this is provided to both sides of the stud. Where the studs are part of a system offering lateral restraint to a structure, a minimum of layer of category or sheathing must be provided. Where wind reversal occurs, both faces must be sheathed to prevent buckling. Characteristic Load on the Support According to EC For Solid Timber C, C and Glulam GL 8 b) Type Flange b * h [mm] Characteristic load per stud in kn a) C C GL 8 C C GL 8 C C GL 8 SW SW 0 SW 90 * * * a) The design values have to be calculated in the following way: N d = N k * k mod / γ m where: N k tabular value, k mod modification factor, γ m partial factor for material properties b) For sole plate / top plate of mm height Calculation Assumptions: Load discharge takes place in the middle of the joist Even load distribution on both flanges
