- Always
The precamber is always taken into account. - EN 1993-1-1 (5.8)
The precamber is only taken into account if the slenderness ratio is greater than in Formula (5.8) of the standard EN 1993‑1‑1 (see Image 01). - DIN 18800 (207)
For calculations of existing buildings, this option has been left in the program according to the withdrawn standard DIN 18800. - Manually
Here, you can specify a value for the member coefficient ε0. The member coefficient is determined according to the formula in Image 02.
Question
How does the activation of the precamber imperfection work?
Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. You just specify the surface geometry and the timber panel elements are generated using an internal member-surface construct, including the simulation of the connection flexibility.
Use the "Rib" component to define any number of longitudinal ribs on a member plate. By specifying a reference object, you can automatically specify welds on it.
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.
Shear walls and deep beams of a building model are available as independent objects in the design add-ons. This allows for faster filtering of the objects in results, as well as better documentation in the printout report.
