Abstract:
There is a need for displacement-based approaches for anchorage design that will consider realistic anchorage behavior by accounting for relevant parameters: anchor stiffness, baseplate geometry, anchorage pattern, and other factors. The article provides a discussion of the general concept of linear and nonlinear spring models suitable for the calculation of anchorage forces.
