'Typical' is hardly the right word for any of our work. But this is just one project where hand calculations would have been virtually impossible: a couple of small cranes on a light superstructure with complicated openings and reinforcements, and multiple load cases and combinations:

 

Aluminium /aluminu superstructure   Crane support structure   Stresses in foundation

 

Stresses in support structure   Stresses in superstructure   Stresses in superstructure

 

Another one where hand calculations or classification rules would not work well: a very complex and flexible bow structure, and with very difficult access for welding. But the designers and builders did an excellent job, and it is still in place:

 

Bow structure with bulb   Deflections in bulb due to sea loads   Stresses in bulb due to sea loads

 

Stresses in bulb due to sea loads - details   Stresses in bulb due to sea loads - details   Stresses in bulb due to sea loads - details
