In the present study, a new stiffness matrix for arch beams had been derived using finite element method. Transverse shear deformation was included in the derivation.The present stiffness matrix could be used in both linear and nonlinear analysis of concrete and steel arch beams. The new stiffness matrix had been used in some applications of both curved thick and thin arch beams. The conclusion shows a very good agreement between the present study and the results of exact solution of other researchers. The maximum difference in deflection was found to be (9%). Also the influence of shear deformations was found to be significant in the thick arch example with a ratio of (10%).
