In static and dynamic analysis of a large complex structure,one may merely beinterested in the stresses and displacements at some important locations.A new solution techniquefor structural analysis with FEM is proposed in this paper by which those important unknowns areseparated from the rest.In static analysis the important unknows can be found directly.In dynamicanalysis all mass and exciting forces can be condensed onto a small number of predetermined pointsin order to make the dynamic analysis much simplified.A large scale problem can be solved with asmall capacity computer quickly.
