Analiza stanu naprężeń i przemieszczeń konstrukcji aluminiowej z wymienianymi elementami

The paper concerns the non-linear analysis of stresses and displacements in an aluminium truss tower. The Ramberg – Osgood material model was assumed. This model introduced power type relation between stresses and strains. In order to identify the inverse relation, a neural network was used. Because of the need to strengthen the tower, a number of aluminium bars was replaced by steel bars. The perfect elastic material model was assumed for the steel bars. The analysis of stresses and extreme displacements was performed during the cyclic loading and unloading of the system. Two global unloading processes were considered: elastic and elastic-plastic processes. The relationship between the load factor and deflection of the top of the tower is shown. Analysis was performed using a hybrid FEM/ANN program.
