concreteproperties.utils.get_service_strain#

get_service_strain(point: Tuple[float], point_na: Tuple[float], theta: float, kappa: float) → float[source]#

Determines the strain at point point given curvcature kappa and neutral axis angle theta. Positive strain is compression.

Parameters

  • point (Tuple[float]) – Point at which to evaluate the strain

  • point_na (Tuple[float]) – Point on the neutral axis

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

  • kappa (float) – Curvature

Returns

Strain

Return type

float
