Structural Analysis of Fan Section of Air Handling Unit KMW ZR 30 9/22
on Dynamic Load Defined by Seismic Spectrum OLKILUOTO 3

2.2. Boundary conditions
Mounting the unit to the ground was modeled by means of withdrawal of all
translational and rotational degrees of freedom of nodes lying on the lower surface of
the base C-shapes , Fig. 9.

Fig. 9. Boundary conditions
A load in the form of spectrum was applied to the ground in the direction of the smallest
stiffness of the air handling unit, i.e. in axis Z [4]. The input spectrum was defined as an
acceleration function from frequency, Fig. 10.
