XBeam2D Loads

Loads

Every load (node load, beam load or node displacements) are inserted per load case.

Load cases

Beam load

Node load

Node displacement

Input of the load cases

No.

This number is generated automatically. You can not change this number

Description

Free text to describe the load case

Type

The type of load. Dependent on the type of load, standard combination factors psi0, psi1, and psi2 are determined according to the Eurocode.

These combination factors are offered as a standard by entering the load combinations. However, these values can be adapted.

Automatically two load combinations are generated. Permanent and variable loads.

Automatically generate combinations

When you enter/change load combinations, the load combinations are automatically generated. You can also change these combinations and expand them.

Sequence load cases

With a click on the right mouse button, the context menu shown below is opened. With these functions you can easily adapt the sequence of the load cases and/or insert load cases.

Insert

A new load case is created, and inserted above the current load case.

Delete

The load case is deleted, including all the loads

Copy

The load case is copied, including all the loads

Move up/ move down

A load can be moved up and down a line.

Copy loads from..

Every load from an already existing load case can be copied. The dialog box shown below is opened. Herein you choose the load case from which you want to copy the loads.

Load combinations

No.

This number is automatically generated. You can not change this number.

Description

Free text space to describe the load combination

Type

The type of load (ULS - ultimate limit state, ULS- fire, SLS-serviceability limit state, quasi permanent). Dependent on the type of combination, standard values for the combination factors (psi) and the load factor (gamma) are offered according to the Eurocode. But these values can be adapted.

Columns with load cases

For all the load cases, columns are created. In that way, a table appears in which all the combinations are shown. Every cell contains 2 values in the syntax : combination factor x load factor.

When you click on the cell the following dialog box appears. Here you can adapt both values.

For the combination factor and the load factor combo-boxes are offered including the standard values from which you can choose. You can also insert an own value. This gives a lot of freedom. If you for instance take one of the values as zero, the product of the two values obviously is zero as well. In that case the cell is showed 'empty'. This is only to make things clear.

Standard there are three load combinations generated. (ULS (6.10a), ULS (6.10b) and SLS)

Sequence load combinations

With a click on the right mouse button, the context menu shown below is opened. With these functions you can easily adapt the sequence of the load cases and/or insert load cases.

Insert

A new load combination is created and inserted above the current load case.

Delete

The load combination is deleted.

Copy

The load combination is copied.

Move up/ move down

A load combination can be moved up and down a line.

Copy ULS combination to SLS

Every load combination of the type ULS will be copied as type SLS. The load factors are set to 1.

Beam Loads

Beam loads are inserted in a local beam coordinate system. See Design arrangement.

The dialog box shown below is opened.

beamload

Load case

Choice for the load case. Here you can directly insert a new load case.

Type of load

Choose the type of load you want to add.

type	description
	even distributed load, or varying load
	point force  - F-load
	moment - M-load

q1

The magnitude of the load. For the q-load the magnitude of the load at the beginning in kN/m. For a point load the amplitude of the load in kN. For a moment the magnitude of the load in kNm.

With plus min you can change the sign of the loads very easy. Standard the sign is at minbecause this is most common.

q2

Only for the q-load the magnitude of the load at the end in kN/m.

a

The distance in mm where the load starts, counted from the begin node of the beam.

L

Only for the q-load the length of the load should be inserted. Standard the load is going up to the end of the beam.

Angle

Only for the q- and F-load. The angle in degrees to the perpendicular. The direction opposite to the clockwise direction is positive.

Beam angle

The angle in degrees with the global x-axis. The direction opposite to the clockwise direction is positive. With

You can take over the angle from the previous section.

z

The distance in the z-direction in mm relative to the reference line. The reference line is adjustable. 'z relative to top', 'z relative to centerline', 'z relative to bottom'.

This distance is only relevant for lateral-torsional buckling resistance check .

Table

Beam loads can also be added/changed in the table. It does not matter. It is also possible to change in between graphical input and numerical input via tables.
