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.
