Investigation of Shear Behavior and Ductility of Shear Connectors in Composite Beams with Cold-Formed Steel Sections Ref.No.SSTCRC2588
1. Introduction
Based on the previously published studies on the behavior of shear connectors in composite beams with cold-formed steel sections, the current project aims to investigate the influential parameters affecting the behavior of shear connectors through experimental testing and numerical modeling using ABAQUS.
The project is expected to develop empirical relationships for estimating the shear capacity and ductility of the connections. Moreover, by comparing these derived equations with those proposed in internationally recognized design codes (e.g., EC4), the project may propose modifications or improved formulations to existing code provisions where discrepancies or limitations are identified.
2. Research Progress
-A detailed literature review and identification of research gaps have been completed.
-Preliminary finite element simulations using ABAQUS are underway.
3. Cooperation Required
-Support with experimental testing (push-out tests).
-Validation of numerical models.
-Funding for material procurement and lab equipment.
-International dissemination and collaboration on code recommendations.
4. Benefits and Outputs
-Improved understanding of shear connector performance in CFS composite systems.
-Potential recommendations for improving EC4 design formulas.
-Broader application of cold-formed steel in structural systems through validated connectors.
-At least 2 peer-reviewed journal articles in Scopus/SCI-indexed journals.
-Comparison chart between code provisions and derived empirical formulas.
-Recommendations for code enhancement.
-Potential design guide for practitioners.
