Can you design and detail U or Z-shaped sections with Continuous Beam/Slab Design?
Continuous Beam/Slab Design allows you to design sections with or without top and bottom flanges. A section has a single web, and its top and bottom flanges (if specified) are assumed to have the same vertical centre line. You can move the web sideways relative to the flanges using the web offset parameter. Within these parameters, the following shapes are possible:
- Rectangular (no flanges)
- I-section (both top and bottom flanges)
- T-section (no bottom flange)
- Inverted T-section (no top flange)
- L-section (top or bottom flange with web offset to the side)
- U-section on its side (top and bottom flanges with same width, and web offset to the side)
For other sections, e.g. a U-section (gutter) or a Z-section, design may be possible. Enter an equivalent I or T-section (see below) with the same overall area, area of web (used for shear calculations) and moment of inertia (Ix) values. Since the program does not consider out-of-plane bending, it does not matter if the Iy value of the equivalent section is not accurate.
With the correct equivalent area and stiffness values, the program can perform all the design calculations. When it comes to detailing the steel reinforcement, however, you may be able to do some basic layouts in the program with additional editing in Padds.
