With LimitState:SLAB it’s simple to analyse a problem with complex reinforcement patterns. Simply define the primary and secondary reinforcement directions and the associated moments of resistance and the software will take care of the rest.

Since LimitState:SLAB uses rigorous mathematical optimization to automatically consider vast numbers of failure modes, there is no longer a worry that the critical failure mode has been missed. This has always been a concern with hand-based yield-line analysis.
