Summary for decision-makers

LIGNO® structure X, co-developed with Dietrich's, is an online software dedicated to timber construction professionals. It covers the entire design process, from preliminary sizing to certified static calculations according to European EC/DIN and SIA standards. Integrable with existing practices, it allows for testing variations and ensuring the reliability of technical choices, while automating regulatory checks.

The tool offers advanced management of large spans, vibration comfort, and the configurability of timber-framed panels. It promotes cost optimization and a reduced material footprint, while meeting safety and sustainability requirements for commercial, public, and multi-family residential buildings.

With LIGNO® structure X, Lignotrend offers new online static calculation software dedicated to the optimized dimensioning of LIGNO® cross-laminated timber (CLT) ribbed and box-section elements. This solution aims for a dual objective: to ensure the reliability of structural calculations while reducing material consumption from the earliest design phases.

A static calculation software designed for timber construction

Developed in partnership with Dietrich's, a recognized specialist in software for timber construction, LIGNO® X structure is aimed at Architects, structural engineers et timber construction companiesThe tool covers the entire planning process: from the Simplified preliminary dimensioning until certified static calculation, directly product-oriented.

"LIGNO® structure X was designed to bring architectural design and structural engineering closer together, without disrupting the workflow."

Accessible online, the software integrates easily into existing practices. It allows you to quickly test constructive variants and to refine the technical choices before the execution phases.

Reliable sizing, in accordance with European standards

The software ensures a calculation in accordance with EC/DIN and SIA standards, based on actual product data derived from LIGNO® systems. This approach guarantees a high reliability of results, including for complex configurations.

The integrated features include:

taking into account concentrated point charges ;
la fire resistance testing for up to 90 minutes ;
the analysis of complex static situations, with variable supports and spans.

"Automating the checks saves time while ensuring the reliability of the calculation assumptions."

Long spans and vibration comfort integrated into the calculation

LIGNO® structure X stands out for its ability to efficiently dimension long-range elements, thanks to a optimized rib configurationThe software also incorporates analysis of the vibratory behavior, a determining factor for the comfort of use of wooden floors.

This feature is particularly relevant for the office buildings public facilities or collective housingwhere the requirements for comfort and structural performance are high.

Advanced configurability of LIGNO® elements

The software offers a complete freedom of configuration Ribbed elements made of cross-laminated timber. Design teams can integrate various technical options from the calculation stage:

variants with or without acoustic function ;
additional layers dedicated to fire resistance;
layer " Plus " for the passage of technical networks.

This approach promotes a economic optimization of sizingby precisely adjusting the sections to the actual needs of the project, without unnecessary oversizing.

"Structural safety and material optimization are addressed simultaneously, within the same computing environment."

A tool geared towards performance and material efficiency

By centralizing calculations, regulatory checks, and construction variants, LIGNO® X structure actively participates in A more efficient and economical timber constructionOptimizing the sections helps to reduce the material footprint, while maintaining high levels of safety and durability.

Thanks to a intuitive interfaceThe learning curve remains quick, even for the early design phases. The software thus becomes a tool to aid decision, serving technically sound and economically coherent timber projects.
