In the RX-TIMBER module, there is the "Edge Beam" feature. What exactly does this option do?

This option allows you to determine whether to design an edge beam or an inner beam arranged between the individual spans. The load application differs as follows:

Inner beam:
${\mathrm q}_{\mathrm k}\;=\;{\mathrm q}_{\mathrm k'}\;\cdot\;\mathrm a\;\cdot\;\mathrm k$

Edge beam:
${\mathrm q}_{\mathrm k}\;=\;{\mathrm q}_{\mathrm k'}\;\cdot\;\left(\frac{\mathrm a}2\;+\;\mathrm ü\right)\;\cdot\;\mathrm k$

a is the beam or rafter spacing
ü is the roof overhang on the gable
k is the load factor for the effect of continuity
pk' is the surface load in kN/m²

The application area is shown in Figure 02.
