INCREASING SUSTAINABILITY OF THE HOUSING STOCK BY AVOIDING DAMAGE CAUSED BY THE SOIL-STRUCTURE RESONANCE
Dinu BRATOSIN
In any dynamic system, the coincidence between natural period and excitation period (the resonance) lead to extremely large dynamic amplification. For example a linear system with damping of order 25% the dynamic amplification factor has values between d…
