摘要：

This　article　reviews　the　researches　and　applications　on　a　new　finite　element　method-Base　Force　Element　Method　(BFEM)　using　a　concept　of　base　forces　proposed　by　Gao.　The　analysis　results　show　the　BFEM　is　consistent　with　those　of　the　theoretical　solutions.　The　BFEM　on　complementary　energy　principle　shows　good　performances　compared　with　the　traditional　4-node　quadrilateral　isoparametric　element　(Q4　model).　For　high　geometrically　nonlinear　problem,　the　BFEM　on　complementary　energy　principle　shows　some　advantages　compared　with　the　4-node　quadrilateral　reduced　integration　element　(Q4R　model).　The　BFEM　is　simple　and　effective.　It　is　new　idea　of　FEM　and　has　widely　application　extension.
