The first time you draw a beam, a profile needs to be chosen / inserted. There is asked what kind of profile you want to add. Also if you want to enter a new profile, there is asked what kind of profile you want to insert.

Remark:

You can adapt all profile dimensions by clicking on the concerning values in the dimension lines.


Profile name:

You can enter the profile name here, or select a profile from the database. You can also directly type IPE160, HEA200 or HE200A here.

Do you want to enter a common steel profile from the database, click on the 3 dots... at the right side of the input field.

Wikipedia encyclopedia

After you selected a basic shape, you can subsequently adapt all the profile dimensions by clicking on the concerning numbers in the dimension line. You can also adapt the profile dimensions of the standard profiles by the use of this method.


E

The elasticity modulus, which is adaptable.


Angle

You can rotate the profile among an angle

Concrete

Cross sectional shape

You can choose from a big amount of cross sectional shapes. When you chose a shape, you can subsequently adapt the profile dimensions by clicking on the concerning values in the dimension lines.


Concrete top layer

Setting whether you want to insert a in-situ concrete top layer with a different concrete grade


Prefab

Setting whether you want to use prefab concrete


Concrete grade

The concrete grade


Steel grade

The steel grade of the basic and additional reinforcement.


Creep coefficient

The creep coefficient of concrete. By this coefficient the effective creep coefficient is calculated according to EN 1992-1-1 art. 5.8.4.

You can insert the creep coefficient yourself or you can have it calculated. See Creep. When the creep coefficient is calculated, a detailed calculation according to EN 1992-1-1 B.1 is displayed in the output as well.


Granule diameter

The nominal granule diameter of concrete


Granule diameter

The nominal granule diameter of concrete


h

The height of the concrete cross section in mm


b

The width of the concrete cross section in mm


h concrete layer

The height of the in-situ concrete top layer in mm

Syntax 2: <diameter>-<ctc distance> [+<diameter>-<ctc distance>...]

Syntax 3: <mm2> [ / <diameter>]


2nd layer

Basic reinforcement top / bottom in the second layer


Additional reinforcement diameters

The diameters by which the additional reinforcement is designed


Layers

When designing a floor, the option if the basis reinforcement is in the first or in the second layer


Transverse reinforcement

When designing a floor, the diameter of the transverse reinforcement

Diameters

Stirrup diameters


Distances

Stirrup distances


Number of stirrup sections

The number of stirrup sections. For shear force this is normally 2.


Angle compression strut

Angle compression strut in degrees


Minimum shear reinforcement

Setting whether the minimum shear reinforcement should be taken in to account.


Concrete interface

In the case of a in-situ concrete top layer, the pouring surface can be entered here.

Wikipedia encyclopedia


h

Height of the concrete cross section for the shear force calculation in mm.


b

Width of the concrete cross section for the shear force calculation in mm.
