title = "Residual Stress Evaluation on Cold-Formed Steel C-Section by X-Ray Diffraction",
abstract = "It is known that the existence of residual stress in cold-formed steel profile plays an important role in determining the nominal strength of the profile in resisting the external forces. Ignoring the residual stress will be very risky due to the serviceability and ultimate strength requirements of the structure constructed from these profiles. This study focuses on the determination of residual stress from local manufacture cold-formed steel lip channel C-sections which are widely used today for the construction of residential roof truss. Two types of cold-formed steel from two different manufactures have been investigated from the residual stresses in the cold-formed lip channel C-sections and the flat steel sheets before being formed into the lip channel C-section by X-Ray Diffraction apparatus. The results show that the tension stress is measured on the flanges surface, while the compression stress is found in the web surface. The residual stress in the bent area of lip channel C-section changes significantly, while the residual stress in flat steel sheet experiences compression. In addition, the residual stress in PC-065-1 specimen is around 200 MPa, while it is about 150 MPa in LB-065-1, whereas for the flat steel sheet specimen of PC-065-1 it is around 100 MPa, while in LB-065-1 it is as high as 240 MPa.",
