ASCE 7-05 Supplement 2

Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 9 and may not reflect current behavior.

The ASCE 7-05 Minimum Design Loads for Buildings and Other Structures, used for all wind and seismic load generation procedures, has been updated for Supplement 2, issued Dec 18, 2007.

1. Minimum Seismic Response Co-efficient C_s

   The minimum value of the seismic response co-efficient C_s has been changed from 0.1 to the maximum of 0.1 and .044 I S_ds . In the change from ASCE 7-02 to ASCE-7 05 it had changed from .044 I S_ds to 0.1, evidently what was intended was that both limits be maintained.

2. References

   The reference to Supplement 2 is made in the informational dialog boxes Welcome, Help/About, and Building Codes, but not in any other references to ASCE 7.
