The topic of this final year project is experimental validation of the force method on a statically indeterminate beam. The selected structure is one degree statically indeterminate two-span beam over with a concentrated force in the second span. The force method assumes that by releasing some connections (reactions) the structure is transformed into a statically determined (so-called primary) structure for which the displacement/rotation from external (real) and unit load are calculated at the position and in the direction of the released connection. Using these quantities, it is possible to determine the value of force or moment at the position of released connection from the compatibility equation and solve the whole system. In this way, formulas dependent on the magnitude of external load and the span of the structure are derived in this work, by means of which it is possible to determine the values of all reactions in the support. After the problem is solved theoretically, we are moving to the laboratory to measure reactions and displacements on a model of the structure, both for the selected (statically indeterminate) and the primary structure, where both external and unit load are taken into account. A detailed comparison of experimental and theoretical results shows that calculated results and experimental measurements show an excellent agreement.
