This tab contains settings related to the nail plate mounting and design.
Optimize design (time consuming)
- In this method of nail plate design, more plate positions and rotations are verified than in standard design. This method of calculation can provide more economical results than the standard design method, but the disadvantage is a significant slowdown in design.
Generate auxiliary nail plates
- This setting automatically inserts an additional nail plate into the apex or eaves detail where the joint is not sufficiently covered by the main nail plate.
Do not consider transport forces in the analysis
- If this setting is checked, the program does not take into account the minimum design forces prescribed by the relevant design standard (e.g. paragraph 9.2.1(8) in EN 1995-1-1) for handling and erection situations when designing the nail plates. This setting can be used, for example, when assessing older structures for the effects of new loads when the trusses are already embedded in the structure and will no longer be handled.
Ineffective nail plate edge
- A setting that determines the width of the ineffective edge of the nail plate. The ineffective edge of the plate takes into account inaccuracies in the placement of the nail plates during the manufacture of the trusses. The truss manufacturing standard EN 14250 specifies that the ineffective edge should be equal to 10mm for trusses designed to EN 1995-1-1.
This part contains parameters of press. The program produces warnings in case that the nail plate size is exceeding entered parameters.
