Occasionally, Shearwalls is unable to distribute forces to the shearwall segments by equalizing the deflection of each segment due to non-convergence of the numerical routine used.
Warning Message
If this happens, the program now outputs a note below the Shear Design table indicating the affected shearlines.
Inconsistency of Deflection and Design Forces
In such a case, the force on the segment used for shearwall design could be markedly different than the force used for deflection analysis. This has been corrected, and they are .now the same. However, it should be noted that these forces do not result in equal deflections on the shearlines, and the value selected is just one in the succession of non-converging iterations that can oscillate between very different values. We recommend turning to capacity-based rigidities for load distribution if this occurs.
