Re: CBC CODE SR VALUE

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hi Gerard,

Sorry I confused you. Since I don't really have the CBC Code, I have no idea
which chapter this equation is in. Anyway, If you happen to find this
equation in CBC( I am sure it is in somewhere in the CBC Code), could you
please tell me what's the difference between the design base shear of CBC
and UBC? Any help is appreciated.


Chapter 31 of the CBC is for special construction (Flood resistant
construction & Membrane Structures).

I do not see a Chapter 31A (the A suffix is for DSA projects (public
schools).
What version of the CBC is this? I am looking in the 2001 CBC which is
basically the 1998 CBC.

The base shear for structures is calculated in Chapter 16 of the CBC.

What I am aware of is that Vsc = V (SR)   (CBC 31A-1?)

Vsc is the design base shear.  This seems different from the design base
shear used in UBC Code.  I am asking this because I am gonna redesign a
building which was originally designed by the CBC Code. However, I am
not
familiar with this Code and I need to figure out what's the design base
shear used before as per CBC.



Can you be a little more specific as to where in the CBC you are coming
across this term or what you are trying to do with it?

Hi,

Is there anyone familiar with the CBC Code can tell me what's the
definition
of Spectral Ratio and how to determine it?  Thanks
