concreteproperties.utils.point_on_neutral_axis#

point_on_neutral_axis(extreme_fibre: Tuple[float], d_n: float, theta: float) → Tuple[float][source]#

Returns a point on the neutral axis given an extreme fibre, a depth to the neutral axis and a neutral axis angle.

Parameters

  • extreme_fibre (Tuple[float]) – Global coordinate of the extreme compression fibre

  • d_n (float) – Depth of the neutral axis from the extreme compression fibre

  • theta (float) – Angle (in radians) the neutral axis makes with the horizontal axis (\(-\pi \leq \theta \leq \pi\))

Returns

Point on the neutral axis in global coordinates (x, y)

Return type

Tuple[float]
