Abstract/Summary The topological interlocking is a principle whereby structural elements are arranged in such a way that no internal element can be pulled out of the structure without disturbing the neighbours, while separate blocks still can move independently within the geometric co nstraints. It is hypothesised that the main features of vibrations in such structures can be modelled by a system of coupled bilinear oscillators . oscillators with the springs having different stiffness in compression and tension. In a single bilinear oscillator this is known to lead to the emergence of multi-harmonic and sub-harmonic resonances. We investigate a system consisted of two coupled bilinear oscillators and propose a method of determination resonance frequencies.
