Wood armer method
Method for design of reinforcement for concrete shells.
Wood Armer is useful because it allows moment triads from grillages (Mx, My, Mxy) to be transformed into simple bending moments in two directions for reinforcement design. This is important because the twisting moment Mxy can be significant. 
An alternative to Wood Armer is the method of Denton and Burgoyne, see 'The assessment of reinforced concrete slabs', SR Denton and CJ Burgoyne, 'The Structural Engineer', Volume 74, Number 9, May 1996. This is useful where the reinforcement is already known e.g. in a existing bridge slab.
