2018 NDS® Standards Wood Design Software
The National Design Specification Standards® (NDS) for Wood Construction (ANSI/AWC NDS-2018) incorporates design provisions for both allowable stress design (ASD) and load and resistance factor design (LRFD). This specification is adopted in all model building codes in the United States and is developed by the American Wood Council (AWC). With this add-on module, SkyCiv Structural Design Software allows users to design timber structures modeled with member elements according to this standard.
The module performs all cross-section resistance designs, stability analysis, and deformation analysis provided by the national design specification for wood construction. In timber construction, the serviceability limit state represents an important design. The conservative limit deformation is preset, but can be modified if necessary.
Wood Design Software Features:
-
Rectangular and Round Wood Shapes
- Supports both ASD and LRFD provisions
- Multiple material type, including Lumber and Glulam
- Auto calculation of all adjustment factors for all members
- Detailed Documentation to help you get started

Powerful Structural Analysis And Design

Automatic Calculation of NDS® Adjustment Factors for all Members
Calculating the adjustment factor for each wood member can be a tedious process. This design module (implementing the NDS® standards) automatically calculates these adjustment factors for both ASD and LRFD provisions, saving you time and allowing you to turn projects around faster.

Fully Integrated with SkyCiv Structural 3D Analysis Software
To make the job easier, SkyCiv has powerful Structural Analysis software that is completely integrated with your NDS® wood design module. Build your model, import ASCE load combinations, run the analysis and with a click of a button run an NDS® 2018 wood beam design. Work quickly and easily by having your analysis and design completely integrated in one workflow.

Clear and Easy Output
Reviewing the results can be half the battle. With this design module, the NDS® results specifically show the adjustment factor and relevant checks being performed. SkyCiv has clear reporting, including this summary table in PDF format. The simple green, yellow and red highlights help users to distinguish between passing and failing members.
