| Abstract | ||
| Cold-formed steel (CFS) sections are popular in structural and architectural applications because of their lightweight properties and high strength. To reduce floor height, different types of openings are added to the web of CFS beams, facilitating the passage of building services through the beams. This study aims to investigate the effectiveness of circular web openings in CFS beams using numerical simulations with finite element analysis (FEA) software (ABAQUS). Nonlinear three-dimensional finite element models (FEMs) for two CFS lipped channels were created and validated against experimental test results to determine failure mode and ultimate load-vertical displacement relationships. The models were then used to predict the bending behavior of CFS beams with circular web openings by varying the diameter and location of holes. The results showed that the load capacity of the beams decreased slightly when the ratio of hole diameter to web height (d_w/h_w) increased up to 0.5. However, there was a more significant decrease in load capacity when (d_w/h_w) ranged from 0.5 to 0.7. | ||
