A Failure Criterion for Steel-Concrete Composite Walls

This paper generates a failure criterion model to analyze the ultimate strength of a steel-concrete sandwich composite (SC) wall subject to biaxial membrane forces, which are tension and compression on each side of the wall and in-plane shear. The failure criterion is demonstrated in principal stress space and σx - σy - τxy space, respectively. Test data in literature for a steel concrete composite wall is summarized and 7 shear wall tests are conducted to verify the model.
