Technical analysis
Wind zones, temporary exposure, restraint and continuous load paths for large steel roofs.
Engineering scope
- Principle
- Separate roof field, perimeter, corner and opening zones using the project wind design.
- Verification
- Temporary restraint during installation is not the final roof-system resistance and must be planned separately.
- Field control
- Use approved calculations, connection design, mock-ups and required pull-out or system tests.
System decision
Start with the actual roof or wall build-up, climate, indoor condition and risk at the relevant interface. Product data must be connected to a defined layer and detail.
Documentation and acceptance
Keep design details, approved product data, delivery labels, batch records, mock-ups, concealed-work photographs and repairs traceable to the installed area.
