EYel, EZel (Options)
|
To specify how the load is applied on the elements. | Setting | Description |
|---|
| No Option selected |
Lane points are created along the element axes. |
| EYel and EZel |
The cross-section eccentricities will be considered. Lane points are created at the origin of the cross-section coordinate system. |
| EYel |
The cross-section eccentricity in y direction will be considered. Lane points at level of cross-section coordinate origin above element gravity axis. |
| EZel |
The cross-section eccentricity in z direction will be considered in addition to the user defined eccentricity ez. |
|
|
El-from, El-to, El-step
|
Elements where lane points are created. |
|
Ratio / Distance to node (Switch)
|
| Setting | Description |
|---|
| Ratio |
Definition of the position as ratio between distance from the start node and total distance between start and end node. |
| Distance |
Definition of the position as distance from the start node. |
|
|
First beam
|
Definition of the position at lane begin (first element of the series) | Setting | Description |
|---|
| x/D-Anf. |
Ratio between dist. from the start node and dist. between start and end node |
| dx-Anf |
Distance of the lane from the start node of the element. |
|
|
Last beam
|
Definition of the position at lane end (last element of the series) | Setting | Description |
|---|
| x/D-End. |
Ratio between dist. from the start node and dist. between start and end node |
| dx-End |
Distance of the lane from the start node of the element. |
|
|
ey, ez
|
Eccentricity of the load application point perpendicular to the element axis in local coordinate directions. Distance related in accordance with options EYel, EZel (see above) |
|
Phi
|
Dynamic coefficient for this lane. Note: The influence values are multiplied with this factor phi. This allows for instance for defining a lane related dynamic allowance (although in practice more often related to the load trains). However, if this factor is dependent on the span length and different in different spans, the selective definition for the individual lane points may be useful. An other possible application is a lane with variable width and uniform surface load. In this case it is advantageous to define a load train for width 1 m, and to define the actual width at the individual lane point as factor phi.
|
|
Ndiv
|
The number of required sub-divisions in the elements. Lane points are created at element begin, element end and any here defined subdivision points |
|
Orthogonal to lane
|
