Technical Background
As a methods of structural analysis, the matrix stiffness method is particularly suited for computer-automated analysis of complex structures including the statically indeterminate type. It is a matrix method that makes use of the members' stiffness relations for computing member forces and displacements in structures. In applying the method, the system must be modeled as a set of simpler, idealized elements interconnected at the nodes. The material stiffness properties of these elements are then, through matrix mathematics, compiled into a single matrix equation which governs the behaviour of the entire idealized structure. The structure’s unknown displacements and forces can then be determined by solving this equation.
EasyCiv uses Matrix Stiffness Method to calculate reactions, deflections, and member forces. Moment, shear, reaction, axial and deflection diagrams can be visualized after analysis. Animated deflection diagram can also be viewed.
As the stiffness matrix in Matrix Stiffness Method is large sparse matrix, it is very infeasible to manipulate using standard dense-matrix algorithms. Specialized algorithms and data structures is used in storing and manipulating sparse matrices. Also, to increase the efficiency, iterative method is used at solving stiffness equation. All those features add up to a powerful analysis tool for you.
Note: Easyciv is to assist you with your analysis and simulation and is not a substitute for your professional judgment or your own independent analysis, simulation or other activities, including those with respect to product stress, safety and utility.
