Variable Element Load

This load type allows for defining a function (program variable) for describing variable loadings on a series of elements.

Note: For detailed load explanation see also RM Bridge Load Types Library .

Using a cover function allows for assigning different loading functions to different elements of the series. An ordinal number referring to the position in the element series (the internal Variable IQVAR) is used for governing the assignment of the different loading functions.

Setting

Description

From, To, Step

Element series to be loaded

Assembly

Alternative to load assignment via element series: Name of the assembly to be loaded. The specified load is applied to every element of the specified assembly.

DX, DY, DZ

Load direction vector. The entered vector is internally normalized to a length of 1; specifying a vector with other length does not influence the loading intensity.

Default: no default, direction must be prescribed

Global / Local

Selection of the related direction system (global or local)

I-Var1, I-Var2

Parameter for calculating the internal variable IQVAR to be used for evaluating any cover function for assigning different tables to different elements Formula for calculating IQVAR:

IQVAR = I-Var1 + (n-1) · I-Var2

with n as consecutive ordinal number of the given element series.

Setting	Description
I-Var1 = I-Var2 = 0	Direct assignment of the loading function without cover function

Ndiv

Number of subdivisions of the loading function

Table

Name of the loading table (function), which has been defined as variable.

Real length / Projection

Load intensities related to the real (clear) element lengths or to the length of the projection normal to the load direction

Element-normalised length

Abscissa value of the loading function is X/L (relative distance from the element begin)

Element-length

Abscissa value of the loading function is the distance from the element begin

Element-global X-axis

Abscissa value of the loading function is the global X coordinate

Element-global Y-axis

Abscissa value of the loading function is the global Y coordinate

Element-global Z-axis

Abscissa value of the loading function is the global Z coordinate
