Determinação de linhas de influência através de computadores digitais pelo método das deformações impostas
The author develops the formulas and the programming necessary to transform a program firstly destinated to the analysis of a structure in a program for the determination of influence lines for the same structure. The studies are general and independent of the basic program or of the type of structure; a particular example is given utilizing the program proposed by Gere and Weaver for the analysis of plane frames and adapting it for the determination of influence lines in plane frames. The physical principles used to obtain the influence lines, characterized in the title of the work by "Method of the forced deformations" are based on Land's and Betti's theorems and are demonstrated in Beluzzi. Block diagram, Fortran Listtings and sample problems of the program for plane frames, are given in the appendixes.
