Model

Because the building is located in a seismic area, timber materials can reduce the horizontal load impact due to their characteristics (lightness and ductility). The structure is a 6-story CLT wall system, which absorbs vertical and horizontal loads better.

Additionally, the complete prefabrication of the CLT panels reduced the assembly time to only 6 weeks. Thermal bridging was also reduced, which increased the moisture control of the panels to ensure an optimal indoor climate.

Dlubal customers EGOIN and Estudi M103 SLP cooperated in the design process under the responsibility of Blazquez Guanter SLP. The program RFEM, including the add-on module RF-LAMINATE, was used to consider the orthotropic stiffness and strength for the structural analysis and design. CLT has the capacity to withstand bidirectional loads, which helps to increase the stiffness compared to a uniaxial structural system.

In RFEM, line hinges based on the actual connection stiffness and nonlinear behavior could easily be considered. The line force diagrams were also produced in RFEM for further consideration in the RF-LIMITS add-on module when designing the connections. The RF-DYNAM Pro add-on module was utilized to calculate the natural vibrations and to perform a modal response spectrum analysis according to the Spanish standard NCSE-02.
