A powerful structural engineering program, YieldLine v4.1 is based on Yield Line Theory for the analysis and
design of quadrilateral orthotropic reinforced concrete slabs supported on two, three, or four sides under a wide range of
support and loading arrangements.
Using the Equilibrium Method, the program automatically identifies the critical
yield-line pattern and then applies the Virtual Work Method to determine design moments for the collapse load.
This automation dramatically reduces the time required to investigate multiple failure mechanisms, enabling
Engineers to reach accurate solutions in a fraction of the time as compared to manual calculations.
YieldLine v4.1 also provides an excellent platform for exploring alternative yield-line
mechanisms and comparing their effects on slab behaviour. It is an invaluable educational and design tool, helping
engineers develop a deeper understanding of yield-line theory while demonstrating how the virtual work solution converges
more rapidly than the equilibrium method.
Use YieldLine v4.1 to :
- Rapidly analyze and design quadrilateral orthotropic reinforced concrete slabs;
- Automatically identify critical collapse mechanisms;
- Calculate design moments; and
- Significantly reduce design time while maintaining engineering accuracy.
