In the design of single-story frame structures, it is important to consider the foundation stiffness, which affects the value of bending moments in columns. The article presents a method and examples of second-order calculations that take into account the effect of support stiffness on the distribution of bending moments in columns supported on footings and foundation piles. The presented method allows more precise, safe and optimal design of slender reinforced concrete columns.
