Based on the theoretical method of normal section strength under flexure and axial force for steel rein-forced concrete members, the simple superposition method and the modified method adopted in the Specification for Design of Steel Reinforced Concrete Structure were introduced. Comparison was made for these methods. Some examples were given to show the usage of the methods. Besides, the eccentricity magnifying coefficient and the axial load linut for steel reinforced concrete column were also introduced.
Keywords:steel  reinforced concrete; normal section; eccentricity magnifying coefficient; axial  load limit
