The present investigation focuses on the flexural behavior of HS steel-concrete composite beams using the commercial finite element (FE) software LS-DYNA. Herein, HS steel-concrete composite beams were constructed with a welded high strength steel I section beam and high strength concrete slab. The proposed three-dimensional FE model is able to simulate the overall flexural behavior, including load deflection behavior and failure modes, of simply supported composite beams subjected to two-point concentrated loads. The reliability of the model is demonstrated by comparisons with experiments results. The load-slip effects on the accuracy of the FE model analysis is also discussed in detail. The accuracy and simplicity of the proposed model make it suitable to predict and/or complement experimental investigations.
