- Abstract
- In certain types of glulam roof structures with large spans, reliable methods for design with respect to instability are lacking. One example is a three-hinged roof truss with steel tension rods as shown in Figure 1.
The types of structures shown in Figure 1 are investigated in the diploma project with the purpose to evaluate and improve the currently used design methods and detailing. Calculation methods and design principles to predict the load-bearing capacity with respect to stability are developed. A theoretical model was created in the frame analysis software Microstran with the purpose to do a parameter study with different variables, e.g. the inclination of the roof, the number of studs, the stud length, the type of joint...

Calculation methods and design principles to predict the load-bearing capacity with respect to stability are developed. A theoretical model was created in the frame analysis software Microstran with the purpose to do a parameter study with different variables, e.g. the inclination of the roof, the number of studs, the stud length, the type of joint (stiffness) and the different structures shown in Figure 1.
Additionally, several tests of a part of a scaled roof structure and their joints were performed and compared with the theoretical model. (Less)
