Investigation of the Flexural Behavior of Built-Cold-Formed Steel Channel Sections

Abstract

The recent trend in the structural steel sector has provided cold formed steel with significant prospects for quick growth and expansion. The escalation in the cost of this light gauge steel facilitated the pursuit of more research. The experimental setup chosen to examine the flexural behavior involved using a built-up back-to-back cold formed channel segment. Both lipped and unlipped channel parts were considered, with several cases taken into account. To conduct the study, the researchers utilized specimens that were both devoid of lips and have lips. Both an empirical research and a computational analysis were conducted for the objective of this study. An investigation was conducted to examine the performance of the specimens under both settings. It was discovered that the specimen with the lipped edge outperformed the other specimen at greater performance levels. The findings were shown in the form of a graph. The specimen underwent a finite element analysis using the ANSYS software.  The findings of both the experimental inquiry and the numerical analysis were thoroughly analyzed during the subsequent debate. Subsequent investigation revealed that specimens measuring 2.5 millimeters in thickness had outstanding performance in the flexural test. Examining the specimen for variable thickness can also be done by making use of the lipped conditions that surround the specimen..
