U-shaped wall coordinate system

[mattfox]

Dear Seismosoft,

I have modelled a U-shaped wall in SeismoStruct v5.2 and the computed moments (when displacement is parallel to the flanges)do not equal those found from experimental testing of the wall and analyses using other programmes. When the same file (originally created in v5.2) is run in v6 the moments match the expected values. It appears that in v5.2 the origin of the local coordinate system does not coincide with the section centroid, whereas in v6 it does.

Is this simply an error in v5.2 or is there another reason?

Regards,

Matt Fox

Dear Matt Fox,

This was indeed an error corrected in v6 of SeismoStruct.
