摘要: The novel idea of by-pass structures is introduced for dynamic multi-scale systems such as elongated multiply supported bridges or tall multi-storey buildings. prevent catastrophic vibrational damage to occur because resonances, which are easily overlooked in current design procedures based on industrial computer packages. ideas can also be applied the and study metamaterials photonic/phononic crystals. solution a model problem an elementary cell provides insights into wave spectrum multi-structures this enables simple isolation frequency ranges troublesome resonance modes may occur.
