CONSPAN allows the user to enter a starting skew angle as well as an ending skew angle for each span. In LRFD mode, when using the AASHTO formulae for computing the Moment Distribution skew correction factors, the smaller of these two angles is used. When computing the Shear Distribution skew correction factors, the larger of the two skew angles specified for the spans is used. When the refined method of analysis is used in either specification mode, the program sets up the grillage model considering the true bridge geometry created by these two skew angles. The input fields are grayed out in the Standard Specifications (LFD) mode, unless the option to use refined methods of analysis has been selected in the Analysis Factors dialog box.
