Verification of bearing capacity of nails

This verification is required only in certain countries and is performed only when checked in the frame "Settings". The magnitude of active earth pressure is reduced using a coefficient Kn, which can also be introduced in the frame "Settings". The recommended (experimentally determined) value is Kn = 0,85

Forces transmitted by individual nails are determined such that a particular portion of the calculated earth pressure is assigned to a given bench. Each nail is then loaded by the corresponding portion of the active earth pressure.   

Forces transmitted by individual nails

The nail force is provided by:

where: b - nail spacing
α - nail inclination
kn - reduction coefficient
Ta,vod - active earth pressure acting on a given bench
