Wittywood, Spain's First Timber Office Building in Barcelona, Spain

Dlubal customer Estudi M103, an architecture office for structural consulting and calculation reports, was commissioned to carry out the structural consulting of the first office building built entirely of wood in Spain, using Dlubal RFEM software. It is an office building with a ground floor and 4 above-ground stories, located on Calle Llacuna 42 in Barcelona. With this type of building, construction periods are shortened due to the use of new sustainable materials, and even carbon emissions are reduced by 50% during construction.

The above-ground structure is composed of GL24h glued-laminated timber columns and cross-laminated timber (CLT) cores of a thickness of 4.72 inches. The floors are supported by GL28h double beams and are composed of prefabricated CLT panels of a thickness of 4.72 inches with GL24h ribs. The wood construction and engineering company Madergia, also a Dlubal customer, was responsible for assembling the structure.

For the calculation and design of the building, loading from self-weight, live load, wind, and snow was considered. They also checked the natural frequencies of the entire structure using RF-DYNAM Pro for dynamic analysis. For the calculation and design of the timber beams and columns, they used the RF-TIMBER Pro add-on module to perform both the ULS and the fire resistance design. Likewise, for the calculation and design of the CLT panels, they used the RF-LAMINATE add-on module, creating up to 9 panel configurations.
