Approtch to the planning of SkanDek
Procedure for projecting SkanDek
When using SkanDek panels, the engineer must provide the following input before designing the elements:
- Static report
- Dead load, wind load, snow load, incl. snow accumulation, potential payload
- Static system for both vertical and horizontal forces
- Ductile response requirements
- Requirements for eigenfrequency/acceleration for separating floor
The static report must account for the static system, incl. placement of stabilising walls or cross bracing, as well as the size of diaphragm forces, to ensure that there is no confusion about the static mode of operation.
SkanDek is designed to be able to transfer the shear forces on diaphragm, but separate stringers must be put in place, which is not part of SkanDek’s delivery. The calculation of stringers and their attachment to the stabilising system is likewise the engineerâ€™s responsibility.
SkanDek is subsequently responsible for:
- Calculation of SkanDek elements according to the stated loads
- Design of attachments to bearings/stringers
- Preparation of a possible report for the SkanDek panels, which can be used as a supplement to the static report for the building.
If an overview is desired of the various possibilities the builder has when using SkanDek elements, the calculation programs can be used to advantage.
For roof constructions, the program for division of carrier lines can be used to determine carrier lines and span directions because the program takes into account the most economic division. The starting point is a U-value of 0.15 W/K*m2.
