Displacements in the stabilizing system of a glulam beam-and-post system

The provisions for developing a beam-and-post building system of glulam are examined for the Swedish market. The building system should provide open spaces through long-span floors combined with apartment floors, reaching a total height of 5-6 stories. Building multi-storey houses in timber requires a strong and stiff stabilizing system assuring safety and comfort for their users. Large movements are unacceptable risking damage on interior claddings and even nausea with the inhabitants on the upper floors. Stabilization can be achieved through diagonal bracing, moment stiff connections or diaphragm action. In this work a special stabilizing element based on diaphragm action is proposed. A parametric study of the stabilization system against lateral loads for a beam-and-post building system is presented based on traditional and numerical analyses. The aim of the paper is to establish the limitations for the stabilizing element to function within a multi-storey beam-and-post system. The study is a first step towards introducing an optimized beam-and-post building system in timber to the Swedish market.Godkänd; 2008; 20080616 (gabtlu)Pelar-balksystem för höga trähu
