Assigning the joists
The procedure for assigning the joists is explained in the Graphical
User Interface manual.
The STAAD joists database includes the weight per length of the
joists. So, for selfweight computations in the model, the weight of
the joist is automatically considered.
An example of a structure with joist (command file input data) is
shown below.
