Program for statically determinate and indeterminate space trusses, with springs, settles, thermal changes and fabrication errors, using the stiffness method, and verified with SAP2000's results.
Graphically represents the state of the stresses or strains, using Mohr's Circle. The program performs the necessary calculations to find the principal directions and principal values of a symmetric tensor in XYZ Cartesian coordinates, and the maximum values for the shear stress or shear strain. In-plane case, the stress or strain that act on plane defined by angle θxy (counterclockwise positive), the program additionally shows the normal stresses or strains, shear stresses or strains, and the angle necessary for the stresses or strains to be maximum. In a three-dimensional case, the stress or strain act on plane defined by normal vector VNP (three-dimensional vector), the program additionally shows the normal and shear stress or strain vectors.
Program for analysis of grids, with springs and settles, using the stiffness method, and verified with SAP2000's results.
Program for Plane frame analysis, with springs, settles, nodal coordinates, thermal changes and fabrication errors, using the stiffness method, and verified with SAP2000's results. In this update, the program shows the shear and moment diagram for the frame or beam, and doing a modal analysis, by calculating the lateral stiffness matrix of a structure.
