Seismic Load Generation in Log File – Miscellaneous Changes

Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 10.0 and may not reflect current behavior

1. Header

   The header to the section has been reformatted to be consistent with the wind load header, and gives the procedure used, either ASCE 7-10 12.8 Equivalent Lateral Force Procedure or ASCE 7-10 11.7 and 1.4 for Category A

2. Distribution of Base Shear Table

   The table showing the distribution of base shear to the building levels has been expanded to show the values of Cvx in Eqn’s 12.8-11 and 12.8-12, and the value of Vx in equation 12.8-13.

3. Design Category A Equation

   The Force equation for Seismic Design Category A, Fx = 0.01 wx from 1.4-1, has been added to the list of equations in the seismic load generation section of the log file.

4. Equation for Fj

   The equation for Fj now indicates the design code clause it most closely can be said to be derived from, 12.8.4.1, in order to have clauses by each entry for readability.

5. Maximum Ss Note (Change 144)

   The note for maximum Ss value in the log file due to 12.1.8.3 changes "does not use" to "is not limited by".

6. Spelling Errors

   The letter el is used in place of the number one in the heading to the base shear table. This has been corrected.

   The User Input and Source section know refers to Site Class F rather than f.
