This study investigates the Experimental and Finite Element (FE) analysis of Steel Concrete Filled Tubes (CFTs) subjected to monotonic and cyclic bending loads, including both constant and variable amplitudes. Eight CFT specimens, identified as C1-C8, underwent rigorous testing under these loading conditions, with their responses meticulously recorded. Furthermore, the experimental tests were replicated using ABAQUS, a widely adopted FE software, for comparative analysis. The examination included strain measurements, load-displacement curves, and failure modes to elucidate the behavior of the CFTs. FE models were developed to simulate identical loading scenarios as the experiments, providing a numerical representation of the CFTs response. Comparison of results from experimental tests and FE simulations was conducted to evaluate the accuracy of the numerical models. The study’s findings enhance understanding of the structural characteristics and performance of CFTs in bending, offering valuable insights for the design and analysis of CFT structures in various engineering applications, ensuring their safety and effectiveness.

Abstract
This study investigates the Experimental and Finite Element (FE) analysis of Steel Concrete Filled Tubes (CFTs) subjected to monotonic and cyclic bending loads, including both constant and variable amplitudes. Eight CFT specimens, identified as C1-C8, underwent rigorous testing under these loading conditions, with their responses meticulously recorded. Furthermore, the experimental tests were replicated using ABAQUS, a widely adopted FE software, for comparative analysis. The examination included strain measurements, load-displacement curves, and failure modes to elucidate the behavior of the CFTs. FE models were developed to simulate identical loading scenarios as the experiments, providing a numerical representation of the CFTs response. Comparison of results from experimental tests and FE simulations was conducted to evaluate the accuracy of the numerical models. The study’s findings enhance understanding of the structural characteristics and performance of CFTs in bending, offering valuable insights for the design and analysis of CFT structures in various engineering applications, ensuring their safety and effectiveness.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
