Three full-scale two-span composite beams with corrugated webs were prepared with different amounts of SCPs. Symmetric two-point loads were applied at each span to simulate continuous flexural behavior, and the load–deflection relationships, failure modes, and steel–concrete interface slips were recorded. The test results showed flexure-dominated behavior with plastic hinges forming in the regions of maximum positive and negative moments and confirmed that a reduced degree of composite action leads to systematic decreases in both ultimate resistance and initial stiffness. A mechanical model was developed in which the horizontal shear resistance (<ce:math altimg=\"si1.svg\"></ce:math>) is expressed as the sum of the bond resistance and the SCPs bearing resistances, and the plastic moment capacities were evaluated using the plastic stress distribution method in AISC 360-22 combined with the equivalent rectangular stress block in ACI 318-25. By incorporating these into a plastic-hinge-based virtual work formulation, a closed-form expression for the ultimate resistance (<ce:math altimg=\"si2.svg\"></ce:math>) of full-scale two-span composite beams was derived. The predicted horizontal shear capacities, plastic moments, and ultimate resistances of both fully and partially composite specimens showed good agreement with the experimental results. Within the experimental range investigated in this study, the derived relationship between <ce:math altimg=\"si3.svg\"></ce:math> and <ce:math altimg=\"si4.svg\"></ce:math> provides a preliminary means of quantifying the degree of composite action in continuous corrugated-web composite beam systems.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"18 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148883815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study combines experimental bending tests, simplified theoretical analysis, and digital image correlation (DIC). It aims to provide insights into the effects of the punched shear connection on flexural rigidity and moment capacity. A total of six specimens, including both conventional flat-interface CFST beams and those with the patented interface, were tested. Results indicate that although end slip is reduced, the presence of punched voids decreases the overall stiffness and ultimate bending moment. Local DIC analysis reveals localized strain concentrations around the punched regions. Stiffness and bending moment results were compared with predictions from Eurocode 4, AISC, and CIDECT. Serviceability stiffness is generally overestimated, although Eurocode 4 provides the closest approximation, with <ce:math altimg=\"si1.svg\"></ce:math>/EC4 ratios of 0.99 for flat specimens and 0.85 for those with the punched connection. The ultimate bending moment is predicted with only minor underestimations.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"23 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148883818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
