Systematic design of glulam trusses
The design of a structure should be regarded as the design of a system. In this licentiate thesis a method (concurrent engineering) for the design of systems is studied parallel with the development of the system itself. The purpose of the work is twofold: To study the application of concurrent engineering (CE) as a method to manage the design work for the design of a glulam truss. To develop a glulam truss and investigate if it can be made competitive on the Swedish market. The qualitative study started with the formation of a CE team consisting of an architect, a contractor and a manufacturer of glulam with the researcher as the project manager. The idea in CE is to let members from different parts of the design work (design, production and manufacturing) solve the problem together. Through the concurrent work of these members a proposal of a glulam truss was posed. The proposal was then verified and refined by the CE team through several iterations between resistance considerations and production issues. The qualitative study showed that the members of the CE team are equally important for the success of the development project. The project manager needs to be independent and have a wide knowledge base. Furthermore, the production issues were investigated early in the design process, which is an advantage for the manufacturer of the truss. The quantitative study focused heavily on the solution for the joint in the glulam truss. A connection type new to the Swedish market was proposed; nails with slotted-in steel plates. The joint consists of steel plates placed in internal slots in the glulam member which is assembled by shooting the nails through the glulam and the steel plates with a nailer. Medium-sized joints were tested in tension parallel to the grain and the resistance was found to be on average 8.35 kN/nail and two steel plates. Production considerations for the joint type revealed that sawing the slots to accommodate the steel plates could be a problem and this was further investigated in laboratory ...
