Table 3.4 Joint types with stiffeners

	Tapered column base
	Restrained column base plate with stiffeners in center of flanges
	Restrained column base plate with stiffeners on both sides of column

In this window section, you can define the geometric parameters of the stiffeners. You can use the button to define the material separately, unless the Use the column material for other joint components check box in Window 1.1 General Data has been selected.

For restrained column base plates with stiffeners, you can enter the length of the vertical and horizontal trimmings.

In this section, you can define the thicknesses of the stiffener welds depending on the joint type. The individual parameters are illustrated in the 3D graphic on the right.

For hinged column footings with stiffeners, you can define a horizontal stiffener in this section. Select the check box to activate the text boxes where you can define the thickness and the weld of the stiffener in accordance with the sketch.

If you have selected the Base plate with channel sections joint type in Window 1.1 General Data (see Figure 3.6), the name of Window 1.8 is Stiffeners and Crossbars and it looks as follows.

The Material of the cross-sections can be selected in a library by using the buttons.

The Length and Gap between crossbars text boxes specify the geometric parameters.
