Solid slab spanning between two supports (BAEL 91)
Design a one-way reinforced concrete solid slab to BAEL 91: loads, bending moments, span reinforcement per metre and shear. Worked example.
What the sheet calculates
- Permanent load, including the slab's self-weight
- Ultimate (ULS) load
- Simply supported moment M0, then span and support moments
- Span reinforcement per metre width
- Shear stress
Worked example
Calculated by the BÉTONIQ PRO engine with the inputs below. It is the same working as in the software and in the Word calculation report.
The calculation output is in French, as in the software.
