DR. SONG JAN BECHTEL CORPORATION HOUSTON,
TX DR. A. J. FERRANTE STRUDL EUROPE srl MILAN,
ITALY
3

• THE CASE
• BECHTEL CORPORATION WON A VERY
• IMPORTANT DESIGN AND CONSTRUCTION
• PROJECT IN AUSTRALIA
• THE PROBLEM
• GTSTRUDL DOES NOT CURRENTLY INCLUDE
• THE AUSTRALIAN AS4100 DESIGN CODE AMONG
• ITS DESIGN PROCEDURES

4

• THE SOLUTION
• IMPLEMENT A GTSTRUDL POST-PROCESSOR
• THAT, WORKING FROM GTSTRUDL DBX FILES,
• CAN PERFORM CODE CHECK AND SELECTION
• OPERATIONS BASED ON THE AS4100 CODE
• THE IMPLEMENTATION TASK WAS ASSIGNED TO
• STRUDL EUROPE SRL, FROM MILAN, ITALY,
• THAT HAD ALREADY EXTENSIVE EXPERIENCE
• IN IMPLEMENTING GTSTRUDL POST-
• PROCESSORS

5

• THE BASIC SPECIFICATIONS
• MODELING AND ANALYSIS DONE IN GTSTRUDL
• DESIGN CHECK AND SELECTION DONE IN PROGRAM
• AS4100 DESIGN IMPLEMENTATION TO BE COMPLETE
• SENT UPDATED PROPERTIES BACK TO GTSTRUDL
• DEVELOPMENT, VALIDATION AND
• DOCUMENTATION IN BE DONE IN
• THREE MONTHS

6

• REQUESTED SHAPES
• 
  1.0 I Shapes
• 1.1 S and H Shapes
• 1.2 HP Shapes
• 1.3 M Shapes
• 1.4 UB and UC Shapes
• 2.0 CHANNELS
• 3.0 SINGLE ANGLES
• 4.0 TEES
• 4. DOUBLE ANGLES
• 4.4 Equal legs back-to-back shapes
• 4.5 Long legs back-to-back shapes
• 4.6 Short legs back-to-back shapes
• 5.0 SOLID ROUND BARS
• 5.1 PIPES, CHS
• 6.1 SQUARE and RECTANGULAR BARS
• 6.2 STRUCTURAL TUBING, RHS, SHS

7

• THE GTSTRUDL STRUDL_AS4100 LINK
• FIRST STEP (GTSTRUDL )
• Structural Model Definition
• Structural Analysis
• Generation of DBX (ModelResults) Files
• SECOND STEP (STRUDL_AS4100 )
• Generation of DBX (ModelResults) Files
• Specification of Additional Design data
• Check and Select Design Operations
• Generation of Updated Properties File
• THIRD STEP (GTSTRUDL )
• Read Updated Properties File (and iterate, if
  needed)
