Partial Uniform Load
The partial UDL is used to apply distributed forces and moments on beam elements over a part of the element length. The direction of loading can be specified either in the global or in the local coordinate system.
The options Real length, Projection, Load/Unit length, Load mult. by CS width, Load mult. by CS depth, and Nodal load are available as described for UDL.
Concentric partial uniform element load – load types QTG, QTL
| Load Type | Description |
|---|---|
| QTG | Concentric partial UDL - Uniformly distributed concentric element load defined in the global coordinate system and acting over a part of the element length. Input parameters are the load intensity components in global directions (QX, QY, QZ), and the start and end point of the loaded length either in terms of proportions of the element length (option Relative: A/L, C/L), or in terms of distances from the element begin (option Length: A, C). |
| QTL | Uniformly distributed concentric element load defined in the local element coordinate system and acting over a part of the element length. |
Eccentric partial uniform element load - QTZG , QTZL, QTYG, QTYL, QZZG, QYYG
For all eccentric partial uniform element loads, the definition of the start and end points is currently restricted to be done in terms of distances (A, C) from the element begin.
| Load Type | Description |
|---|---|
| QTZG | Eccentric partial UDL, acting over a part of the element length (parameters QX, QY, QZglobal,distances A, C,local z-eccentricity Ecc). |
| QTZL | Eccentric partial UDL acting over a part of the element length (parameters QX, QY, QZlocal,distances A, C,local z-eccentricity Ecc). |
| QTYG | Eccentric partial UDL acting over a part of the element length (parameters QX, QY, QZglobal,distances A, C,local y-eccentricity Ecc). |
| QTYL | Eccentric partial UDL acting over a part of the element length (parameters QX, QY, QZlocal,distances A, C,local y-eccentricity Ecc). |
| QZZG | Eccentric partial UDL, acting over a part of the element length (parameters QX, QY, QZglobal,distances A, C,local z-eccentricity Eccrelated to the cross-section reference point rather than to the centroid); the z-component of the cross-section eccentricity is automatically added internally. |
| QZZL | Eccentric partial UDL, acting over a part of the element length (parameters QX, QY, QZlocal,distances A, C,local z-eccentricity Eccrelated to the cross-section reference point rather than to the centroid); the z-component of the cross-section eccentricity is automatically added internally. |
| QYYG | Eccentric partial UDL, acting over a part of the element length (parameters QX, QY, QZglobal,distances A, C,local y-eccentricity Eccrelated to the cross-section reference point rather than to the centroid); the y-component of the cross-section eccentricity is automatically added internally. |
| QYYL | Eccentric partial UDL, acting over a part of the element length (parameters QX, QY, QZlocal,distances A, C,local y-eccentricity Eccrelated to the cross-section reference point rather than to the centroid); the y-component of the cross-section eccentricity is automatically added internally. |
Note: Eccentric partial element loads can only have either a y-eccentricity or a z-eccentricity. Load vectors with both, a y- and a z-eccentricity, have to be split into 2 parts (e.g. a vector in z-direction with y-eccentricity and a vector in y-direction with z-eccentricity).
