GPRF No.: 96.09
DATE: February 13, 1996
DESCRIPTION:
The CHECK MODEL feature in GTModeler and GTMenu will compute the
incorrect weight of the structure if the structure contains angle
sections selected from the steel tables. In addition, the INERTIA LOADS
will be incorrect also. In computing the weight of the structure or the
inertia loads, the cross sectional area is either doubled or quadrupled
for angle sections such as single angles, double equal angles and double
angles with the short or long legs back to back. Thus, the weight and
inertia loads will be higher than they should be.
If the input file is generated from GTModeler or GTMenu, the input file
(modlxxxx.inp) will contain the correct table and section name for the
steel tables which contain the correct cross sectional properties. If
the model is translated back to GTSTRUDL by choosing the Command Mode
menu pick, the model will also contain the correct table and section name
for the steel tables which contain the correct cross sectional
properties.
Workaround:
Do not use GTMODELER or GTMenu to create INERTIA LOADS if the model
contains angle profiles selected from the steel tables. The LEAD LOAD
command can be used in Command Mode to create correct inertia loads. The
weight output in GTModeler should be ignored if the model contains angle
profiles selected from the steel tables.
