2.5.5 Required Longitudinal Reinforcement

Required Longitudinal Reinforcement

The longitudinal reinforcement to be used at the bottom side of the surface is determined from the design membrane forces. In the design details, the output occurs separately for the two reinforcement directions.

$a_{s,\text{dim}+z,1} = \frac{n{s}_{\text{end},+z,{\varphi }_1}}{{\sigma }_{s,+z,1}} = \frac{158.344}{465.93} = 3.4 {\text{cm}}^2/m$

$a_{s,\text{dim}+z,2} = \frac{n{s}_{\text{end},+z,{\varphi }_2}}{{\sigma }_{s,+z,2}} = \frac{11.116}{465.93} = 0.24 {\text{cm}}^2/m$

The reinforcement for the surface's top side is determined in the same manner.
