DC-Calcs V22 - the highlights!
All about the new DC-Calcs update version 22

With new beam- and panel-shaped wooden materials, structures with slender component cross-sections can be designed. In order for these materials to properly exploit their properties, their lamellae direction and longitudinal alignment have to be oriented depending on the designated application. Therefore, we have added the lamellae and grain direction to the material input. That way you can individually align the lamellae for laminated veneer lumber, use glulam on edge for dimensioning board stack ceilings or select the grain direction of sheet-like components depending on the load situation.

We have also extended the material alignment for the cross laminated timber input. With the new tilt angles Q-90° and Q-270°, the top layer of the elements is aligned transverse to the component direction. With the new options, corner cantilevers, for example, can easily be specified in two calculation positions.

It is not uncommon for floor-to-ceiling cross laminated timber elements that span over large wall openings. These wall-like beams carry the loads across patio openings and garage doors, or even act as the suspender beam for suspended ceilings. The dimensioning procedure considers slice effects with regard to cut sizes and deformations. Thus, you can easily provide the verification for beams of any height. 

High loads often cause excessive compression in timber construction. In order to keep these under control at the supports and load application points, steel plates and fully threaded screws can be used in the continuous beam as a lateral pressure reinforcement.

For a convenient definition of your Lignotrend element cross-section of up to 1000 possibilities, a configurator has been implemented in DC-calcs. The elements are produced and approved with support ribs, transverse and additional layers as well as with additional levels possible in the cross-section. Design LIGNO® BSP element cross-sections for ceilings and roofs with DC-calcs in a time-saving, safe and comprehensive way.

While the protection burns down, the component will already heat up and after removal of the measure, the actual burning assessment will start with increased burning. For a realistic verification, take the fire protection measure into account by entering in minutes the protection time.

In the case of connectors, current research requires checking the risk of transverse tensile failure. In DC-calcs, we automatically consider in such cases a specified notching. It is also possible to reinforce the notching by means of fully threaded screws and in that way achieve a higher load-bearing capacity.

Furthermore, for two-piece connectors by Knapp and Pitzl, you can provide proof of fire protection in accordance with the current manufacturer's certificates.
