Dimensional analysis is applied to study the pounding response of two inelastic multidegree freedom (MDOF) structures under simplified earthquake excitation. The forces and deformations collision processes are simulated by adopting improved Kelvin model. characteristics MDOF described bilinear interstory resistance model, representations dimensionless impact force motion equation in process der...

Experimental simulation and parametric studies have been conducted to investigate the effect of pounding in base-isolated (BI) frame structures with expansion gaps. Earthquakes often result extensive damage at joints, which encouraged this experimental evaluation between BI frames. In present research, a series combinations, such as adjacent flexible stiffer frames similar frequency different f...
