In recent years, using cold-formed steel members as structural and complementary structural elements has become very popular. The fact that these elements have thin wall thicknesses (t≤6 mm) due to their manufacturing characteristics makes the buckling and torsional strengths critical in designing these elements. In this study, the flexural strength of clawed C profiles used in the construction industry in our country will be calculated with TS EN 1993-1-3, AISI S100-16, and DSM. After determining the strengths of 72 selected profiles with these design methods, a comparison was made between them, and the performance of the methods was tested. The differences between the methods are shown on the graph.

Son yıllarda soğuk şekil verilmiş çelik elemanların gerek taşıyıcı gerekse tamamlayıcı yapı elemanı olarak kullanımı oldukça popüler hale gelmiştir. Bu elemanların, imalat özelliği gereği ince et kalınlıklarına (t≤6 mm) sahip olması bu elemanların tasarımında burkulma ve burulma dayanımlarını kritik hale getirmektedir. Bu çalışmada ülkemiz inşaat sektöründe kullanıma sunulan tırnaklı C profillerin eğilme dayanımı TS EN 1993-1-3, AISI S100-16 ve DSM ile hesaplanacaktır. Seçilen 72 adet profilin bu tasarım yöntemleri ile dayanımları belirlendikten sonra aralarında karşılaştırılma yapılmış ve yöntemlerin performansı test edilmiştir. Yöntemler arasında oluşan farklar grafik üzerinde gösterilmiştir.
