When we have items in the criteria menu they always apply to the whole model. Only options under the Assign menu can be delegated to particular members.

See this about FloorVibe: communities.bentley.com/.../8142.please-specify-the-location-of-the-floorvibe-exe-program It sounds like you need to install it, or get up to the latest RAM SS version which includes it.

Thanks for your reply, i was designing to Eurocode and when i switched to 5950 it allowed me to input a vibration criteria.

Is there a way of assigning certain frequency criteria to one area of the floor and different frequencies to other areas?
How do you go about using Floorvibe is it an additional piece of software? when I attempt to use "floor vibe" I get a prompt "please specify the location of floor vibe.exe programme using the following dialog"

Within the Ram Steel beam module, you'll find the same settings under Criteria - Design Defaults, but only when the design code is BS 5950. We recommend the use of FloorVibe, which can be launched from within the program - Vibration menu, for evaluation of floor vibration.
