Experimental Study On The Compression And Stiffness Behavior Of A K-Span Corrugated Cold Formed Steel Arch
In this research, 18 different samples of K-span corrugated cold-formed steel arches were tested to investigate the compression resistances and the effective cross-section areas of the K-span section. Furthermore, 12 stiffness tests were conducted to investigate the spring stiffness behaviour of the webs of the cross-sections. The obtained stiffness parameters were used to perform the theoretical calculations of the effective cross section under compression according to EN1993-1-3. The results show that the K-span of 1,1 mm thickness has almost double the ultimate load value as compared to the K-span of 0,8 mm thickness. In addition, the test results indicate that the K-span group of 1,1 mm thickness has a higher spring stiffness value as compared to the K-span of 0,8 mm thickness. The effective area of the cross-section under uniform compression was evaluated and the contribution of corrugations is obtained. The study was conducted at HAMK Tech Research Unit and the research project was commissioned by Kaarirakenne Oy during the summer of 2020.
