Haunch cross-sections
It is quite common that a 1D member contains haunches at one or both of its ends. Sometimes the beam cross-section just simply "changes" its dimension (usually the height), sometimes a special cross-section is made for such a 1D member. This special cross-section consists of two parts – one that remains constant along the whole beam span, and one that "makes" the haunch. SCIA Engineer allows the user to select from a set of pre-defined "haunch" cross-sections.
The procedure for insertion of a "haunch" cross-section into a project is identical with the procedure for any other cross-section type; the user just have to specify the type in the type-selection dialogue, then choose the appropriate shape and size, and oversee or change the required parameters.
As for any other cross-section type, the sectional characteristics such as sectional area, moment of inertia, position of centroid, etc. are calculated automatically by the program. The user may input or modify other cross-section parameters such as material, name, etc.
In addition to the basic sectional characteristics, the program also calculates, designs and displays data such as:
-
shape of a wall stiffener,
-
diagram of warping lines,
-
diagram of shear stress distribution over the cross-section for a unit force acting in Y-direction,
-
diagram of shear stress distribution over the cross-section for a unit force acting in Z-direction,
-
centre lines of the cross-section.
Note: Some of the above mentioned data depend on the shape of the particular cross-section. Therefore, some of the values may not be available for some of the cross-section shapes.
