Experimental Validation of Dynamic Response of Small-Scale Metaconcrete Beams at Resonance Vibration

Structures and their components experience substantially large vibration amplitudes at resonance, which can cause failure. The scope of this study is the utilization silicone-coated steel balls in concrete as damping aggregates to suppress resonance vibration. heavy cores oscillate with a frequency close structure. Due phase difference between vibrations structure, counteract core-coating inclusions are randomly distributed similar standard aggregates. This mixture referred metaconcrete. main goal work validate ability mechanical through laboratory experiments. For purpose, two small-scale metaconcrete beams were cast tested. In free test, exhibited larger ratio compared beam from conventional concrete. measured sweep test. comparison beam, both demonstrated smaller amplitudes. Both experiments verified an improvement dynamic response
