Abstract
The work presented in this thesis deals with investigation of methods to evaluate simultaneous moment and normal force capacity for symmetrical and unsymmetrical thin walled aluminium beams. The beams are supplied by Sapa Building System AB and is used in their glass facade system SFB 4150. The system is constructed in a way that makes it possible to make large glass facades. It is then of interest to investigate the load bearing capacity in terms of normal force and moment which can be substantial in these large facades. Methods that were used to investigate the capacity include building norms, Finite Element (FE) calculations with ABAQUS and make full scale testing of the beams. A comparison between building norms and Finite Element... (More)
The work presented in this thesis deals with investigation of methods to evaluate simultaneous moment and normal force capacity for symmetrical and unsymmetrical thin walled aluminium beams. The beams are supplied by Sapa Building System AB and is used in their glass facade system SFB 4150. The system is constructed in a way that makes it possible to make large glass facades. It is then of interest to investigate the load bearing capacity in terms of normal force and moment which can be substantial in these large facades. Methods that were used to investigate the capacity include building norms, Finite Element (FE) calculations with ABAQUS and make full scale testing of the beams. A comparison between building norms and Finite Element calculations were made that reveal that the building norms are fairly simplified and gives poor results. So to get a more accurate capacity only calculations by FE analysis are employed in the study. A more thoroughly review of the calculation method for the FE analyses is presented at the end of the report. The third method to investigate the capacity that is presented in this report is full scale testing of the beams. This was made for ve types of beams and two load cases for each beam. Every test is then made for two-three beams per load case. The results are then compared with FE analysis in order to verify the analysis method. The comparison shows that the FE analysis results agreed well with the full scale tests. It is therefore recommended to use the FE analysis method to calculate the force capacity for thin walled aluminium beams loaded with simultaneous normal force and moment. With the aid of the FE analysis method, design charts were made.
The purpose of the design charts was to reduce the future work effort of calculating the capacity loaded by simultaneous normal force and moment in the design phase of the glass facade. (Less)
