Wood Armer fomula for skew reinforcement

midas Gen provides design forces in the reinforcement directions for skew reinforcement based on the Wood-Armer

From the analysis results, following plate forces about the local axis are calculated

- mxx

- myy

- mxy

In order to calculate design forces in the reinforcement direction, angle α and φ will be taken as following figure:

x, y: local axis of plate element

1, 2: reinforcement direction

α: angle between local x-direction and reinforcement direction 1

φ: angle between reinforcement direction 1 and reinforcement direction 2

Firstly, internal forces (mxx, myy and mxy) are transformed into the a-b coordinate system.

Then, Wood-Armer moments are calculated as follows:
