Element analysis of prestressed concrete curved beam |
| |
| Abstract: | In order to compile a program for designing structures which contain curved beams, a curved element with prestress load has been analyzed. The element stiffness matrix and the nodal load matrix of the 3D curved beam are derived according to the theory of mechanics. The method for calculating the equivalent nodal load of tendons in curved beam are presented with that for an equivalent straight beam. |
