| Abstract: | This paper introduces the formulas for calculating the inner forces and deformation of non-circular arches with the fundamental formulas,these non-circular arches including parabolic,three-centered,elliptic,hyperbolic and logarithmic spiral arches under constant loads can be calculated.These formulas can be used to write the program for crown cantilever analysis considering the effect of torsion or for accurate calculation of stresses of non-circular arch dams |

| Keywords: | non-circular arch parabola three-center ellipse hyperbola logarithmic spiral torsion |
