How to add a haunch in Prokon Frame
A haunch is created by including a haunch depth in the section designation. To explain how to go about adding a haunch, a work example will be used.
Scenario: Adding a haunch of 300 mm to a 305x102x33 I-section.
- Click on the Input tab in Frame, under the heading Input types located on the ribbon find and click on the Beam Section icon, open the Section database
- From the list of available I-sections, locate and click on section 305x102x33, assign the Section Name RFTR to the section
- Open the section database again, tick the box next to Haunched and define a haunch depth of 0.300m, click on the section 305x102x33, and assign the Section Name HNCH
Note: The overall depth is then taken to be 305mm + 300mm = 605mm
- Under the heading Input types located on the ribbon find and click on the Beams icon
- To add the haunch section, two section names are assigned to the Beam element
Note: The section names are separated with a comma and the section properties will vary linearly along the length of the beam element
- The first and second section names designate the section at the near and far node numbers respectively, i.e., if the hunched section starts at node 6 and ends at node 79 (in this case), the Section Name will be defined as RFTR,HNCH
Suggestion: Verify the haunched section by enabling 3D rendering in the Graphics Options.
