Question

The TIMBER Pro add-on module seems to multiply the shear stress by 1.5. However, the Eurocode does not specify any additional factor. How do you explain this difference?


Answer:

The shear stress of your cross-section may be the average value. The distribution of the shear stress is not constant, however, but parabolic with its maximum in the shear center.

Note that the maximum shear stress of a rectangular section is about 50% higher than the average stress.
