Title: Lateral stiffness of cold-formed steel shear wall panels braced with glass panes: a numerical study
Abstract: Cold-formed steel shear wall panels can often be found in residential, commercial and office buildings. Such load-bearing walls, consisting of a cold-formed steel frame with structural sheeting screwed onto it, act as primary lateral load resisting component that has to maintain the stability and integrity of the structure. Although these panels have some unique advantageous properties, they are characterised by small openings due to closely spaced studs (i.e. the vertical frame members). To increase the building’s transparency, the load-bearing capacities of glass can be utilised by bracing the frames with glass panes instead of traditional sheeting. For this purpose, the traditional screwed connection is transformed into a circumferentially linear adhesive connection between frame and glazing. This modification results in an altered behaviour of the newly developed hybrid cold-formed steel-glass panel compared to a traditional panel. In this research, the aim is to determine the different influence factors on this behaviour by performing a literature survey. By means of numerical modelling, the horizontal stiffness of these newly developed shear wall panels was assessed in the serviceability limit state and the relative displacements between the glass panes and the cold-formed steel frame were determined. This paper reports about the significance of the influence of the width-to-height ratio of the panel, the thickness of the adhesive layer, the thickness of the frame members, the glass thickness and the type of section used for the frame. To find the optimum configuration for given design conditions, all investigated influence factors had to be taken into account, even though their significance varied. The width-to-height ratio, the adhesive thickness and the glass thickness up to values of 8 mm had the most significant influence on the overall behaviour of the hybrid cold-formed steel-glass shear wall panels.
