Drawing internal force curves of three-hinged arches by Excel

Microsoft Excel is an ordinary office software which has powerful data processing and chart functions. The internal forces for every section of three-hinged arches are computed by setting Excel formula and internal functions. And the internal force curves of three-hinged arches are drawn by use of the Excel charts. It is useful for three-hinged arches teaching and increasing students’ interests to learn three-hinged arches to implement the complex three-hinged arch internal force computations, and draw the internal force curves accurately and quickly by use of Excel.
