Structural Analysis of Fan Section of Air Handling Unit KMW ZR 30 4/22
on Dynamic Load Defined by Seismic Spectrum OLKILUOTO 3

2. Finite Element Model of the Unit

2.1. Structure modeling
The finite element model of the Air Handling Unit adequately represents the distribution
of stiffness and mass so that all significant deformation shapes and inertia forces are
properly accounted for under the seismic action considered. The model also accounts
for the contribution of joint regions to the deformability of the Unit. Non-structural
elements, which may influence the response of the primary seismic structure, are also
accounted for.

Parts made of angles, shapes and sections or sheet metal plates were modeled via a
shell elements, see Fig. 1, 2 and 3. Volumetric parts, such as e.g. a fan, have been
modeled by solid elements.
