Theoretical Fundamentals for Computer Supported Collaborative Design od Structures D. Hartmann and D. Bretschneider Department of Civil Engineering Institute for Computational Engineering Ruhr-University of Bochum Germany D. Hartmann / D. Bretschneider
D. Hartmann / D. Bretschneider Introduction Can structural design, including the anthropocentric aspects of collaborative work, be mapped to a software system ?

(i)formalization and representation of the anthropocentric components of collaborative work (ii)computerized support for universally valid project management activities (iii)availability of a holistic and consistent product model of the structure to be designed l l l D. Hartmann / D. Bretschneider Fundamentals three basic features are most vital: complexity and dynamic nature require a generic, abstract reproducible and concise calculus of description ! accomplished through the object-oriented paradigm (OOP) utilizing the Unified Modeling Language (UML)
l l l lcreate two separate subsystems, (i)a process model to represent team computing, independent of structural steel design (COOPERATE) (ii)a structure-oriented product model (PLAKON) D. Hartmann / D. Bretschneider solution approach: ltransform structural design into object classes and class diagrams lconcatenate both subsystems to an integrated system (INDUSYS) lvalidate and streamline the total system lenhance the system incrementally

l l l l l l D. Hartmann / D. Bretschneider lprocess of collaboration preliminary design: - P1 defines the basics of the structure - P1 decides on the team members by means of Team Editor - P1 + A1 + S1 determine load cases - product submodel of preliminary design
l l l l l l D. Hartmann / D. Bretschneider structural analysis: - S1 computes structural response in terms of Stress-resultants - product submodel of structural analysis
l l l D. Hartmann / D. Bretschneider verification: - P1 decomposes total work and defines Task-objects using Project-Editor - P1 + S1 are charged with the verification - product submodel of verification
l l l D. Hartmann / D. Bretschneider structural detailing: - P1 + S1 + A1 + D1 + D2 are working together - P1 is charged with conflict resolutions - product submodel of structural detailing

D. Hartmann / D. Bretschneider Conclusions CSCW-systems provide the potential to create sophisticated structural design l Computing opens further enhancements and improvements (e.g. multi-media inclusion) l implementation of soft issues (social models) is becoming attractive in engineering l new directions (e.g. multi-agent technology) and further research is required in the next years l
