Um sistema computacional para a análise de estruturas de centrais nucleares, formadas por painéis, utilizando-se superelementos

The main purpose of this work is to analyze the linear static behavior of folded-plate structures like the turbine building of a nuclear power plant by the Finite Element Method. Folded-plate isoparametric plane elements with 48 degrees of freedom each, 8 nodal points, in which shear deformations are considered, and super-elements, whose internal degrees of freedom are condensated, are used. Arbitrary shells can be analized too. A brief exposition of the method is present and the developing of the foregoing element and super-element is also shown. A computer program was developed for the CDC-CYBER 175 computer machine and the FORTRAN IV language was used. The coeficients of the equations' system are stored by the technique of block partitioning with a compacted column storage scheme and special attention was dedicated to the preparation of the problem's data and some options were developed for this purpose.
