Based on the computation mechanism,the bearing capacity interactive group of curves N-M for compounds RC elements are established, as well as the brief computation modes, which unify the formula for columns and beams. The formulas simplify calculation, guarantee the accuracy and identify the large and small eccentricity of the element.
Keywords: compound structure; bearing capacity; interactive curve
