Hi,with that transition to the 2007 California Buildng Code - I just got Enercalc 6.0 and looked at the wind module and it references the 2003 IBC and some provisions that are not in the 2006 (or ASCE 7-05) seems like the design wind pressure part of the module won't calculateHas anyone used this program yet for use with the 2006 IBC code?I am also confused in the seismic module in that I have a redundancy factor of 1.3 and it seems like I need to actually math any use a pencil :-) to put this factor in the calculations. I know this a new version and a new code but I seem lost. I am also doing this all by hand to verify what is supposed to happen. Is there anyone to set me straight??Tim RudolphPinyon EngineeringBishop CA
There should be a yes or no question in regard to the following if the program does not calculate this.
Looking at each building direction north=south and east-west If you remove any lateral resisting element (shear wall, frame..) does the removal result in a story strength reduction of more than 33% of the over all story strength.
If the answer is no you can use a rho of 1.0. You have to evaluate both directions.
Now if you have multistory building you check this at all levels that have greater than 35% of the base shear load at that level. If no level has greater than 35% base shear then you can use a rho of 1.0.
Also this check is for SDC of D thru F ...SDC of C and below rho = 0.

Start the year off right. Easy ways to stay in shape in the new year.
