A framework is proposed in which certain well-known concepts of statistical mechanics and thermodynamics can be used and applied to characterize structural systems of interconnected Timoshenko beam elements. We first make the assimilation to a network of nodes linked by potential energy functions that are derived from the stiffness properties of the beams. Then we define a series of thermodynamic quantities inherent to a given structure (i.e.
internal energy
heat
pressure
temperature
entropy
and kinetic energy). With the exception of entropy
all of them have the dimensions of energy. In order to test this new framework
a series of experiments was performed on four structural specimens within the elastic regime.Their configurations were taken from the seismic regulations known as Eurocode 8 in order to have a better based reference for our comparisons. The results are then explained within this new framework.
