CALCULATION OF STATICALLY INDETERMINATE STRUCTURES
Aleksey Shirko, e-mail: a_shirko@tut.by
The application allows you to determine the constraint reactions, build diagrams of the normal forces N, shear forces Q and bending moments M for beams and frames with any number of sections and degree of static indefinability. Reactions identified by a capital letter X. Indexes of reactions, chosen arbitrarily, but you should set the reactions X[1], X[2] and X[3] so that the structure has been kinematically unchanged. The application calculates the deformation (displacements) of the structure in millimeters and displays the displacements of nodes in the horizontal and vertical. It is also possible to calculate the displacement of any point of the structure. In the program has the ability to set the stiffness of each section frame (beams) EI[i]
Example of Table input data and boundary conditions shown in the figure.
