Abstract

Using Stricklin Melhod^[5],we have this paper has derived the formulas for the ge-neration of non-linear element stiffness matrix of a triangle element when considering both the bending and the in-plane membrane forces.A computer programme for the calculation of large deflection and inner forces of shallow shells is designed on theseformulas.The central deflection curve computed by this programme is compared with other pertaining results.
- triangular element,
- non-linear,
