Impact Stiffness of Linear Viscoelastic Model for Seismic Pounding Simulation: An Experimental Evaluation

Pounding between adjacent structures occurs when the separating distance within two buildings is inadequate to contain movement them during an earthquake event. Seismic pounding can lead significant harm or even destruction of neighbouring structures. In creating a model for structural response, impact stiffness considered as critical factor in calculating force throughout collision It important derive realistic values performing numerical simulation forces abutting attain valid results. The objective this study ascertain linear viscoelastic contact model, using data obtained from shaking table experiments neighboring five-storey and 15-storey single-bay steel-frame. steel models were subjected scaled ground acceleration records, far-field near-field. study’s findings indicate that there discrepancy theoretical parameters measured experimental value because assumptions made formulas do not align with actual conditions. accuracy precision formula adopted have been validated comparison Doi: 10.28991/CEJ-2023-09-06-01 Full Text: PDF
