Why is the transversal compression factor kc,90 of 1.0 assumed in the design of support pressure?

Answer

Section 6.1.5 (4) of Eurocode 5 requires to apply the smaller transversal compression coefficient of kc,90 for the concentrated loads that are close to the support.

As an option, it is possible to deactivate the support pressure design in the RX‑TIMBER program and set the corresponding transversal compression stiffening.

If the entered concentrated load is not relevant for design, there is the additional option to assign the user-defined transversal compression factor (Figure 03).
