Abstract:
This thesis presents a method of stress enelysis of curvedstructures to determine nod81 displacements end member forces. In theenalysis,en energy functional composed of strain energy due to bending,exial deformation and work done by externel forces such 8s nodal loed,vertical distributed load , horizontal distributed loed and radial loadis introduced. For equilibrium, the total potentiel energy of the systemis stationery end minimum. Application of the finite element methodyields 8 system of lineer equations and Geuss elimination method isused to solve them.This method is suiteble for curved structures having equetionsof plane curve in rectangular coordinates end unknown erc length. Theequation of plane curve y = y(x) can represent undeformed Centroidalaxis of the circular arch, parabola arch, sine erch and elliptic arch,etc. The results of this enelysis compared fevourebly with the solutionsobtained from classical method end peckege finite element program.
