Natural frequency of buildings

Natural frequency of buildings

Natural frequency of buildings

(OP)
Hai,

 Can any body tell me the usual values of first natural frequency of single storyed buildings which has only two rooms with construction under proper standards?

With Regards,

RE: Natural frequency of buildings

hi!
Maybe, Anyone can't do it for you.
First, if you want to find the usual value of first natural frequency of the building, you have to tell us about a rough width, a rough length and a rough height.
I think so....

P.S. I'm sorry that I write in poor English.

RE: Natural frequency of buildings

May be not more than 10HZ.

RE: Natural frequency of buildings

chh its surprising to hear that the natural frequency would be only 10Hz. Please give some proof for your above statement.

RE: Natural frequency of buildings

its really surprising that the natural frequency of the building would be only 10 Hz.
Any comments friends to solve this query.

RE: Natural frequency of buildings

I have measured several buildings and measured natural frequencies (first mode) in the range of 2 Hertz to 14 Hertz.  Yes most buildings have natural frequencies below 10 Hertz.  By buildings I mean fairly large structures in the order of 3000 metric tons and above.  Smaller objects and lighter structures are anywhere above 100 Hertz.

RE: Natural frequency of buildings

hi,

to support Hatch and Chh:

earthquakes are low frequency vibrations (in the range of 5-10Hz). buildings collapse when resonance occurs during earthquake. hence one can very well assume that building natural frequency is around 10.

White Paper - PLM and ERP: Their Respective Roles in Modern Manufacturing
Leading manufacturers are aligning their people, processes, and tools from initial product ideation through to field service. They do so by providing access to product and enterprise data in the context of each person’s domain expertise. However, it can be complicated and costly to unite engineering with the factory and supply chain. Download Now
White Paper - Medical Device Design Control
Medical device product development is a highly integrated and regulated process. Implementation of a requirements tracking solution requires attention to a variety of nuanced topics. When presented with the task of tracking the many concept relationships in a project of this type, the initial software solution of choice tends to be a two-dimensional text systems. Download Now
