developed by Power Line System Inc., USA for the analysis
and design of transmission line structures. The structure
analysis in TOWER can be linear or non-linear. The non-linear
analysis accounts for the second order geometric effects
due to the displacements. It also treats guys as exact
cable elements and therefore should be used for guyed
TOWER calculates stresses in each
angle member and compares them to allowable values.
For guyed towers, TOWER calculates guy tensions and
compares them to allowable values. In non-linear mode,
it can be used to check the overall stability of the
entire tower or any of its sub-assemblies. TOWER can
be used by itself (stand-alone) or in conjunction with
the line design program PLS-CADD.
Typical uses of TOWER are listed below:
Check the design of an
existing tower for a given design loading tree (stand-alone
design of an existing tower as spotted in an actual line
model (direct link from PLS-CADD).
Develop a table of allowable
wind and weight spans for a range of line angles and given
design criteria (stand-alone use).
Write Structures Files for use by
the companion program PLS-CADD, using either the allowable
spans method or the critical components method. If these
Structures Files include allowable wind and weight spans,
they can be used for minimum cost optimum spotting.
