Toe Width Considering Web Thickness

By applying a special rule, the width of the toe on the flange of a T-bar may be automatically defined at modelling time. It is possible to define this rule for all T-bar endcuts having a toe defined on the flange. The width of this toe is defined by parameter "c" in the endcut standards. The flange geometry of such endcuts is illustrated below.

This rule defines, per endcut type, the extension of the flange toe outside the web. That measure is marked with a 'd' in the sketch below. At modelling time a new toe width C is calculated according to the following formulas:

The customer can control the extension of the flange toe outside the web via a special file in TIL-format. The rule should be written on the following format:

CUT, <endcut type> /D=< extension of the flange toe outside the web>;

The endcut type should be designed to be used for T-bars and have a toe on the flange defined by a C-measure.

Example of a text file defining the extension of the flange toe outside the web:

When this facility is activated the value of 'c' in modelling is irrelevant and need not be given at all except in certain cases as illustrated below ('old' input to the left, 'new' to the right).
