Table 4 The similarity coefficients of the TRTS (partial data refer to [37])
From: Dynamic responses of a train-track-bridge coupled system under earthquakes
Similarity coefficient | Symbol | Scaling equation | Value | Description |
|---|---|---|---|---|
Acceleration | SA | SA = SA | 1/1 | Basic parameter |
Length | SL | SL = SL | 1/10 | Basic parameter |
Stress | Sσ | Sσ = Sσ | 1/2 | Basic parameter |
Elastic modulus | SE | SE = Sσ | 1/2 | |
Force | SF | SF=Sσ·SL2 | 1/200 | |
Stiffness | SS | SS=Sσ·SL | 1/20 | |
Time | ST | ST = (Sl·Sa)0.5 | 0.316 | |
Speed | Sv | Sv = SL / ST | 0.316 |
