Most existing studies focus primarily on the use of screws solely to assemble two channel profiles into built-up sections. This study proposes the use of self-drilling screws for connecting two separated segments of CFS built-up box beam. These box beams are assembled from two channel sections C 75×35×0.75 placed face-to-face. Their flexural strength is investigated by two methods: experiment, and Finite Element Analysis (FEA). The experiment comprises by means of four-point flexural test at simple beam with lateral restraint at support. This study involves a two-stage experimental test, where at the first stage, beams are tested without any connection, and the second stage employs beam with a connection. FEA models have been developed and compared to the experimental results. It is shown that the FEA models can accurately predict the behaviour of CFS built-up box beams with and without connections.

investigated by numerous researchers. Most existing studies focus primarily on the use of screws solely to assemble two channel profiles into built-up sections. This study proposes the use of self-drilling screws for connecting two separated segments of CFS built-up box beam. These box beams are assembled from two channel sections C 75×35×0.75 placed face-to-face. Their flexural strength is investigated by two methods: experiment, and Finite Element Analysis (FEA). The experiment comprises by means of four-point flexural test at simple beam with lateral restraint at support. This study involves a two-stage experimental test, where at the first stage, beams are tested without any connection, and the second stage employs beam with a connection. FEA models have been developed and compared to the experimental results. It is shown that the FEA models can accurately predict the behaviour of CFS built-up box beams with and without connections.\u003c/p\u003e","manuscriptTitle":"Numerical Study of Moment Capacity of Cold-Formed Steel Built-Up Box Beam with Self-Drilling Screw Connection","msid":"","msnumber":"","nonDraftVersions":[{"code":2,"date":"2025-11-04 16:14:03","doi":"10.21203/rs.3.rs-7291060/v2","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}},{"code":1,"date":"2025-08-20 11:58:43","doi":"10.21203/rs.3.rs-7291060/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"872c423d-9400-4d94-8c2f-aa38e0a52979","owner":[],"postedDate":"November 4th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[{"id":57078403,"name":"Physical sciences/Engineering"},{"id":57078404,"name":"Civil Engineering"}],"tags":[],"updatedAt":"2025-09-15T16:38:37+00:00","versionOfRecord":[],"versionCreatedAt":"2025-11-04 16:14:03","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v2","identity":"rs-7291060","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-7291060","identity":"rs-7291060","version":["v2"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
