Structural design report for the CLT project

Tekla Structures, Calculatis® by StoraEnso

PROJECT INFORMATION

In this example, you can see our Structural design report for a CLT timber design project. This was completed for a private client in the Netherlands.
We have included the latest editions of standards and relevant annexes, with National Annex: The Netherlands.

PROJECT DESCRIPTION

We have been using the Stora Enso Calculate
– Version 2.36.0 application for connection design calculations.
The connection reactions were computed utilizing the design software.
The CLT panel connections are computed in accordance with the appropriate standards EN:
EN-1990 Eurocode 0: Basis of structural design
EN-1991 Eurocode 1: Actions on structures
EN-1995 Eurocode 5: Design of timber structures

Timber and CLT detailing for DfMA

Tekla Structures or CadWorks, StoraEnso

PROJECT INFORMATION

Residential building from CLT (cross-laminated timber) and GLT (Glue-laminated timber), in the Netherlands, built in 2020.

PMtech Engineering is an innovative structural design company, that delivers solutions for static calculations for simple/multi-story buildings, based on timber frame modules LVL, GLT or CLT (cross-laminated timber) structures.

PROJECT DESCRIPTION

Standards: The CLT/GLT panels connections are computed by the appropriate standards EN: EN-1990 Eurocode 0: Basis of structural design, EN-1991 Eurocode 1: Actions on structures, EN-1995 Eurocode 5: Design of timber structures and The Netherlands Annex

STRUCTURAL SYSTEM DESCRIPTION:
It has a total area of ~350 m2 and consists of CLT walls, CLT slabs, wood stairs, and GLT beams. The stability of the building has been provided by concrete walls fastened together with screws. CLT slab provides a stiff diaphragm, which transfers horizontal loads to CLT walls, fire resistance class R60

Scope of works:
– Calculations (load collection, stability, connections);
– Communication with architect, MEP engineers, CLT factory, site team;
– Detailing in Tekla Structures;
– Production and installation drawings (DfMA).

Denmark project.
Loading Plan of Wooden Pod, Development of drawings (WSD)

Tekla Structures

PROJECT INFORMATION

• If agreed to by manufacturers at the time of sale, the panels will be loaded in a specific sequence as determined through the shop drawing approval process. (Load plans must be determined at the time of IFC.)
• The trailer will be loaded in a sequence typically following installation order.
• Safety concerns that arise during loading may alter the sequence.

Performed work: 3D-modeling, wooden pod drawings
(Transportation schemas CLT panels).
