Effect of tendon components on design strip cross sections

In many instances the "latitude" and "longitude" tendons may be detailed and constructed in a non-orthogonal manner. This is often ignored in hand or strip calculations but it is a real issue that can affect design criteria such as service, strength and ductility.

RAM Concept considers the force components of all tendons that cross a design strip cross section (or a design section). The following figures show an example.

A skewed design strip with three design cross sections. The latitude tendons are not orthogonal to the longitude tendons.

Perspective shows the central cross section is perpendicular to the latitude tendons which are at the low point. Due to the layout the strip collects a component of the longitude tendon which is at its high point. This configuration may cause design issues.
