The main research area of the Conceptual Structural Design group is to explore collaborations between architecture and structural engineering, focusing on structures that unite structural performance, assembly/construction and visual form into a meaningful whole. In addition to scholarly studies of the issue, the work encompasses studying key structures, function and form as well as taking part in developing actual design and construction projects together with students, design often applying parametric modelling. The main projects realised resent years are the Trondheim HolzBau Pier, the Rjukan pavilion (Torgstova) and Trondheim Gridshell. In these projects, architectural form and structural functionality are inseparable. The design is carried out by parametric modelling usually including parameter regarding architectural, structural as well as manufacturing/construction issues, resulting in accurate and efficient construction and low costs. Working closely with students and phd-candidates developing design concepts and designing and constructing temporary structures provides innovation and knowledge relevant also for the professional practices and the building and construction industry.
