Two Dimensional Isostatic Truss Structures Solver ITSS2D
This solver computes the internal loads on each member of two dimensional isostatic truss structures by using the method of joints.
Since the Theory of Deformations is not considered in this program, displacements of the structures are not computed. All assumptions of Rational Mechanics are made in order to mantain the structure as a rigid body. Besides, only axial loads are assumed, so that torsion, bending and shear stresses are neglected and cannot be determined by this method. All the members of the structure satisfy the simplification hypothesis of the method of joints.
After creating the geometrical structure model by using geom1 and geom2 functions and entering the boundary conditions of the physical problem (bc), external applied loads (extloads) must be entered. Reactions of the isostatic structure are calculated by using reactions function. Once the structure has all the equivalent applied loads (external loads and reactions included), the computation of internal loads on each member is done following a calculation sequence on adjacent nodes with the use of intloads function. The last node is used as verification.
A plot of the structure (numerating all nodes and elements) can be shown by using plotits2d function.
