Example Description
...
In this model, time history analyses the output sampling time interval used is 0.02 seconds and response is calculated for the first 8 seconds of the record. The independent analysis has an output sampling time interval of 0.1 seconds.
Important Note: The AISC section properties in the database file SECTIONS8.PRO are not used in this example and the required section properties are explicitly entered. This is intentional because most of the sections used in the example are older sections not in the current AISC database.
