Coefficient C for Eccentrically loaded bolt groups
Coefficient C for Eccentrically loaded bolt groups
(OP)
Please I need help.
I have a connection using shear tab, with shear and axial forces applied.
1. When is it permitted not to consider the coefficient?
2. How can I obtain the value of C? The fast way.
I also made a spreadsheet (see attachment) for instantaneous center method and I am having problems on converging the bolt forces.

The fast way to obtain C is to use the design aides in AISC bolt chapter. If the design aides do not match your bolt pattern, then I would recommend a spreadsheet (I did not open your spreadsheet). Alternatively, you could do the elastic vector method by hand.
