Up until version 2025.d, the shear check of the bolts was carried out considering the worst-case scenario: the shear plane passing through the threaded zone of the thread.
As of version 2025.d, depending on the plates to be joined and the length of the shear plane, the program evaluates whether the cutting plane is on the threaded or non-threaded part of the thread.
When the thicknesses of the plates to be joined are different, the cutting plane may vary according to the direction in which the bolt is placed, passing through one area or the other. In these cases, the bolt shall be evaluated in both directions and, if in any of them the cutting plane passes through the threaded area, this condition shall be considered in the check.
The length of the shear plane is included in the bolt library. The series of bolts available in the program have been updated to incorporate this information. In projects created with previous versions, the bolt libraries will assign the threaded area a length equal to the length of the thread, as was previously the case.
The libraries can be updated via the library management to include the length of the shear plane. To do this, simply click on the blue arrow icon and select the series to be imported. If you have a customised user library, the same procedure must be followed to update the bolt libraries and then save the customised library again.
