2. Major IAI projects - structural proposed structural model realized in IFC2x2 release – ST2 reinforced concrete – ST3 precast concrete – ST4 steel construction structural analysis * ) *based on ISTforCE structural model IFC2x ST-4 Steel Extension Structural Engineer Checking Engineer Detailing (Steel) Fabrication (Steel) Construction Manager Cost Calculation Architect Facility Manager other disciplines Project Manager HVAC Designer* ST-2/3 RC Extension Checking Engineer Detailing (RC) Fabrication (RC) Construction Manager Cost Calculation ST-4 analysis

3. Structural analysis material independent definition of the structural analysis model, including –structural members, boundary conditions, connections –supports, loads, load combinations ST-4

4. Sample usage scenario sharing of structural models –mechanical system and actions as input information –can be used by several calculation software systems –can be used for getting online and rental services for complex calculations –can be used to return results of the structural calculations enables specializations and involving external experts Actors: Structural engineers, checking engineers Application Objects - Profile specification 1 - Material 1 - Structural elements 1 : - Linear - Planar - Connections between elements 1 - Supports 1 - Actions 2 - Action Combinations 2 Structural Analysis 1) Level 1: Mechanical system 2) Level 2: Actions Actors: Structural engineers, checking engineers
