Limitation: All nodes are imported as connections. Also, the intermediate nodes are imported as connections.
Workaround: To reduce the number of connections, the user can merge the divided girder into a single girder and delete the connections at the intermediate nodes. After synchronization, the internal forces are imported correctly, as if the girder were divided.
Limitation: Design Combinations cannot be imported; only General Combinations are allowed.
Workaround: All of the Design Combinations could be converted to the General Combinations by the CTRL+Copy and CTRL+Paste functions in the Combination Table.
Limitation: Only simple Combinations because of concurrent forces in the joint.
Creating the load combinations in midas GEN NX is based on combining previously defined combinations (Add and Envelope). For now, the BIM link doesn’t allow the import of these multilevel combinations, but allows the import of only two “single-level” types of load combinations:
- Type Add – a combination type Add consists only of individual load cases.
- Type Envelope – a combination type Envelope consists only of individual load cases.
This means that the combination must not consist of: other combinations (Add or Envelope), Moving Load Cases or Settlement Load Cases.
Limitation: Envelope type Lodas cases as Moving load case, settlement load cases, spectral lodas case are not exported.
Workaround: For example, in the case of the moving load, the user has to create a linear load case that causes extreme internal forces in the connection (by the Moving Load Tracer feature, for example), and then use this load case in the add combination.
Limitation: Nodal loads are not imported; only internal force imports are available.
This limitation could cause unbalanced forces in the connection due to nodal loads being entered directly in the node, which basically do not create internal forces on the members.
