Nonsensical Values for Anchorage Deflection (Bug 2677)

Under certain circumstances, the program reported extremely high negative values for anchorage deflection in the Hold-down displacement table. These unrealistic displacements were used in the calculations for deflection, creating nonsensically high deflections.

This has been corrected. It happened under the following circumstances:

Zero Force on Segment

• When the distribution of forces within a line resulted in zero force on a segment, because other stiffer segments draw the entire load.

  Negative Uplift

• When there is no uplift force at a location, that is, the counteracting dead load and/or compressive force from above is greater than the overturning force.
