Modeling and Calculation
The building has the dimensions of approximately W x L x H = 291 ft x 85 ft x 59 ft. The structure was initially modeled in the 3D‑CAD software cadwork. The model was then imported as multiple DXF background layers for each level into RFEM. These layers were the basis for modeling the members and surfaces.
With the use of the RF‑LAMINATE add‑on module, the Nordic cross‑laminated panel properties were defined. The calculation of the internal forces of the whole structure (taking into account the plate stiffnesses calculated in RF‑LAMINATE) was then performed in RFEM. The design of the structural components was carried out separately.
