【Abstract】 By using the consistent algorithm an arbitrary thin walled open cross-section beam finite element is established with the generalized stresses and strains in the wall of beam as basic variables,Numerical results indicate that the displacements and stresses obtained by the present method are quite accurate for engineering practice,and the required computing time and memories are less than that of shell finite element analysis.更多还原
