concreteproperties.utils.get_service_strain#

get_service_strain(point, ecf, eps0, theta, kappa)[source]#

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

Parameters

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

  • ecf (Tuple[float, float]) – Global coordinate of the extreme compressive fibre

  • eps0 (float) – Strain at top fibre

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

  • kappa (float) – Curvature

Returns

float – Strain
