STAAD Commands and Input Instructions

5.13.1 Plate and Shell Element Incidence
Specification
Purpose
This set of commands is used to specify ELEMENTs by defining
the connectivity between JOINTs. REPEAT and REPEAT ALL
commands are available to facilitate generation of repetitive
patterns.
The element incidences must be defined such that the model
developed represents one single structure only, not two or more
separate structures. STAAD is capable of detecting multiple
structures automatically.

Description
ELEMENT INCIDENCES SHELL must be provided immediately
after MEMBER INCIDENCES (if any) are specified. The REPEAT
command causes the previous line of input to be repeated ‘n’
number of times with specified element and joint increments. The
REPEAT ALL command functions similar to the REPEAT
command, except that it repeats all previously specified input back
to the most recent REPEAT ALL command; or to the beginning of
the specification if no previous REPEAT ALL command had been
issued. Use “REPEAT ALL 0 0 0” to start a set of elements that
will be repeated if you don’t want to repeat back to the last
REPEAT ALL.
