BACK

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.

Steel

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.

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

Environmental class

The environmental or exposure class is used for the determination of the required cover. See Exposure classes

Concrete surface

Can be checked, can not be checked or finished

delta_Cdev

Execution tolerance of the concrete cover in mm

Cover

Concrete cover top / bottom in mm

Side cover

Side cover left / right in mm

Basic reinforcement

Basic reinforcement top/bottom

Syntax 1: <amount>x<diameter> [+<amount>x<diameter>...]

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

Concrete trench

Concrete trench in mm

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.

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.

Concrete grade

In case of a in-situ concrete top layer: Concrete grade that needs to be used for the shear force calculation.

Timber

Remark:

You can change the profile sizes by clicking on the concerning values in the dimension line.

Profile name

Enter the profile name or select a profile from the existing database. You can also directly type 75 x 200 of 75 x 225

When you want to enter a known timber profile from the database, click on the 3 dots... on the right side of the input field.

Material

Timber

Type of timber

Timber class

Climate class

Basic shape

You can choose from an amount of basic shapes. In this way you can make the profile yourself.

After you selected a basic shape, you can subsequently adapt all the profile sizes by clicking on the concerning values in the dimension line. You can also can adapt the profile sizes of the standard profiles in this way.

E

The elasticity modulus which is adaptable

Angle

You can rotate the profile among an angle

Build-up selection

With this module you can built up any section.

Input

You can Add, Copy and Delete any profiles here. Using Properties you can change your profile or alter the profile dimensions.

Profile name

Enter the profile name or select from our profile database.

Special input:

1. Half H syntax: "1/2 profile name [ - min dimension ]" Example: 1/2IPE300 or 1/2HE650B-5
2. Rectangular: syntax: "S width x height" of "F width x height" Example: S200x12
3. Hole: syntax: "G width x height" of "H width x height" Example: H50x2
