FE simulation data of the Palisaden CLT building

Palisaden is an eight-storey building in Ås, Norway. The lightweight design features thin wood cladding, no screed, and a combination of exposed CLT and plasterboard-covered walls. A deterministic FE model was developed in APDL (Ansys Parametric Design Language) to compute its modal properties. The set of modeling parameters were the followings: p = [COEF_VERT, COEF_G, FACADE, FOUNDATION, WEIGHT], where COEF_VERT is the scaling factor for the vertical elastic moduli of the CLT walls (along the grain), accounting for uncertainties in the manufacturer’s European Technical Assessment) ETA, COEF_G is the scaling factor for the in-plane shear stiffness of the walls, FACADE is an additional scaling factor used for the external walls to account for the increased shear stiffness of these walls due to the facade, FOUNDATION is a stiffness parameter used in the spring modeling of the foundation beneath the ground floor, and WEIGHT scales the initially estimated total mass of the building. Each parameter was assigned an a-priori uniform distribution, with bounds determined based on best engineering judgment. The following bounds were used: COEF_VERT: [0.5, 1], COEF_G: [1, 3], FACADE: [1, 1.5], FOUNDATION: [7, 10], WEIGHT: [0.8, 1.2] The measurable outputs can be described by the parametrized FE model Palisaden: y = Palisaden(p) = [f1, f2, f3, f4], where fi is the eigenfrequency of the ith mode. x_df.csv contains 9991 random samples of the parameter space with the corresponding headers and y_df.csv the respective outputs of model Palisaden, where f.i is the eigenfrequency of the ith mode.
