Water Sports Center, Formentera, Spain

Customer Project

On the Mediterranean island of Formentera, a new cross-laminated timber building was constructed which is used by a sailing school and a water sports center. The one-story building consists of two separate parts that are connected by low-lying glued-laminated beams in the roof area.

Model Parameters


Marià Castelló designed the project according to ecological building criteria and used materials of natural origin, such as wood. The structural analysis was performed by Kmod Enginyeria en Fusta SL who carried out the strength and serviceability limit state designs with RFEM and RF-LAMINATE. BIM-based planning was also carried out and cadwork software was used.

Structure and Design

The cross-laminated timber roof panels were designed as a pane that transfers the horizontal loads to the transverse walls. All the walls are also made of cross-laminated timber. The connections in the roof and wall elements were modeled with line hinges. The flexibility was considered according to the selected type of bolting. The floor consists of one-way spanning, 6.5m long cross-laminated timber panels on an elastic boundary strip foundation.

One of the greatest challenges in the structural analysis of this building was to additionally stabilize the entire structure at the top by arranging a frame structure made of glued-laminated timber beams with more than one meter height. In some places, these beams serve as cantilevers with a length of six meters, they connect to other beams and form a spatial structure. They were modeled as surfaces in order to better assess the lateral stability. The transversal wind loads on these elements were also considered and evaluated in order to demonstrate the maximum deflection according to the standard.

The RF-LAMINATE add-on module was used to define the CLT panels and the glulam roof beams as surface elements. The add-on module was also used to optimize the surface thicknesses and to design the load-bearing capacity.
