The Screen / feeder is mounted on springs only, the springs will typically have their own natural frequency around 3-6 Hz and the screen / feeder is running at 16Hz. the screen has a self-weight of around 70kN. The frequency response of the structure is a separate issue to the seismic design...
When designing a dynamically affected structure, one supporting a vibrating screen / vibrating feeder, should I consider the self weight of the screen / feeder when assessing the seismic loading condition? And if so, should I take 100% of the self-weight. Bearing in mind that the screen / feeder...
