Tg
|
Characteristic period dependent on ground types according to JTG Table 5.2.3. |
|
Damping
|
Damping ration in %, default value 5% used to calculate Damping correction factor according to JTG 5.2.4. |
|
Consider E1/E2
|
Selects whether the E1 design earthquake or E2 design earthquake shall be applied or not. |
|
Horizontal earthquake
|
Selects whether the vertical earthquake load shall be applied or not.
| Setting | Description |
|---|
|
Acceleration coefficient (H)
|
Horizontal Design Earthquake acceleration dependent on the magnitude of earthquakes that can be expected in the respective region. |
|
Soil coefficient
|
The maximum value of the design spectrum is influenced by the correction value Cs dependent on the ground type and also on the design ground acceleration, JTG Table 5.2.2. |
|
Influence coefficient
|
Depending onto the selected bridge category: A, B, C, D and the investigated earthquake event (E1 or E2) we have the correct Seismic influence coefficient Ci , JTG Table 3.1.4-2. |
|
|
Vertical earthquake
|
Selects whether the vertical earthquake load shall be applied or not.
| Setting | Description |
|---|
|
Acceleration coefficient (V)
|
Vertical Design Earthquake acceleration dependent on the magnitude of earthquakes that can be expected in the respective region. |
|
Response coefficient (R1)
|
Response factor situated in the low period (high frequency) region between 0 and 0.1 seconds of the vertical response spectrum. |
|
Response coefficient (R2)
|
Response factor situated in the high period values above 0.3 sec of the vertical response spectrum. |
|
| Drawing |
Graphical display of the response spectrum. If vertical response spectrum is selected, too, it will be displayed in addition. |
