Abstract: Based on positional FEM, three-node Euler-Bernoulli beam element for large deflection 2D frame analysis is researched. Solution strategy of geometric nonlinear static analysis with three-node Euler-Bernoulli beam element is introduced to the frame structures, and the program flow chart is given, then Matlab language is used to compile program. Simple example is shown at the end of the paper, comparing the numerical results achieved with the analytical and other numerical solutions found in the literature. [Copyright &y& Elsevier]
