Individual load cases (except the load case with the code "dead") may contain joint and member loads. The joint loads are defined using the element <pointLoad> and member loads are defined using the element <lineLoad>.
Point loads
Point loads are defined using the element <pointLoad>. Following attributes are available:
x, y, z | - Forces or deformations in given directions, optional
|
mx, my, mz | - Moments and rotations in given directions, optional
|
points | - List of points where is the load assigned. Obligatory. Example of syntax: the value "1,6,9-12, 3" adds the load into points 1, 3, 6, 9, 10, 11, 12
|
Point load
Member load
Member loads are defined by the element <lineLoad>. The attribute "lines" defines member IDs, which should be loaded by this load. Syntax is described above (example: "1,6,9-12, 3"). Individual types of member loads are defined using following elements:
<singleForce> | |
<singleMoment> | |
<continuous> | - Line load for the whole member length
|
<continuousPart> | - Line load on the part of member length
|
<trapezoidal> | - Trapezoidal load with defined beginning and end
|
The element <singleForce> for single force supports following attributes:
direction | - The load direction. Available values: "x" (global axis x), "y" (global axis y), "z" (global axis z), "1" (local axis 1), "2" (local axis 2), "3" (local axis 3)
|
value | |
angle | - The angle between the force and member axis. Optional, if not defined, the value 90 is used
|
fromStart, fromEnd | - The position from the member beginning (attribute "fromStart") or member end (the attribute "fromEnd"). The value of the attribute defines the distance from reference point. The value with the character % means that the distance is defined using per cents of the member length. Otherwise, the position is defined in meters. Obligatory.
|
Load case with point loads on members 1 and 5
The element <singleMoment> for single moment supports following attributes:
direction | - The load direction. Available values: "x" (global axis x), "y" (global axis y), "z" (global axis z), "1" (local axis 1), "2" (local axis 2), "3" (local axis 3)
|
value | |
fromStart, fromEnd | - The position from the member beginning (attribute "fromStart") or member end (the attribute "fromEnd"). The value of the attribute defines the distance from reference point. The value with the character % means that the distance is defined using per cents of the member length. Otherwise, the position is defined in meters. Obligatory.
|
The element <continuous> for continuous load on the whole member length supports following attributes:
direction | - The load direction. Available values: "x" (global axis x), "y" (global axis y), "z" (global axis z), "1" (local axis 1), "2" (local axis 2), "3" (local axis 3)
|
value | |
angle | - The angle between the force and member axis. Optional, if not defined, the value 90 is used

value | |
angle | - The angle between the load and member axis. Optional, if not defined, the value 90 is used
|
fromStart1, fromEnd1, fromSecond | - The position of load beginning from the member start (attribute "fromStart1") or member end (the attribute "fromEnd1"). The load beginning can be also defined using the position of load end (the attribute "fromSecond"). The value of the attribute defines the distance from reference point. The value with the character % means that the distance is defined using per cents of the member length. Otherwise, the position is defined in meters. Obligatory.
|
fromStart2, fromEnd2, fromFirst | - The position of load beginning from the member start (attribute "fromStart2") or member end (the attribute "fromEnd2"). The load beginning can be also defined using the position of load end (the attribute "fromFirst"). The value of the attribute defines the distance from reference point. The value with the character % means that the distance is defined using per cents of the member length. Otherwise, the position is defined in meters. Obligatory.

|
startValue | - Value of load at the begining, obligatory
|
endValue | - Value of load at the end, obligatory

angle | - The angle between the load and member axis. Optional, if not defined, the value 90 is used
|
fromStart1, fromEnd1, fromSecond | - The position of load beginning from the member start (attribute "fromStart1") or member end (the attribute "fromEnd1"). The load beginning can be also defined using the position of load end (the attribute "fromSecond"). The value of the attribute defines the distance from reference point. The value with the character % means that the distance is defined using per cents of the member length. Otherwise, the position is defined in meters. Obligatory.
|
fromStart2, fromEnd2, fromFirst | - The position of load beginning from the member start (attribute "fromStart2") or member end (the attribute "fromEnd2"). The load beginning can be also defined using the position of load end (the attribute "fromFirst"). The value of the attribute defines the distance from reference point.
