3 Output for calculation for Beta factor

In the numerical output are new values, which are used in calculation β factor according to generals methods. The following new values can be presented in numerical output :

For all methods

MEd,x

is unbalanced transferred   bending moment between the slab and the columns (supports) in of x axis of LCS for punching

MEd,y

is unbalanced transferred   bending moment between the slab and the columns (supports) in of y axis of LCS for punching

For general ( general formula) method

kx,ky

is a coefficient dependent on the ratio between the column dimensions in direction of x(y) axis of LCS for punching

ex(y),i

is eccentricity of  i-th control perimeter related to centroid of cross-section in direction of x(y) axis of LCS for punching

Wx(y),i

is modulus of i-th control perimeter in direction of  x(y) axis of LCS for punching corresponds to a distribution of shear and recalculated to centre of gravity of the control perimeter

For General (EN 1992-1-1,6.4.3(3-5)) method

kx,ky

is a coefficient dependent on the ratio between the column dimensions in direction of x(y) axis of LCS for punching

ex(y),i

is eccentricity of  i-th control perimeter related to centroid of cross-section in direction of x(y) axis of LCS for punching

Wx(y),i

is modulus of i-th control perimeter in direction of  x(y) axis of LCS for punching corresponds to a distribution of shear and recalculated to centre of gravity of the node , where is column (support linked to the slab)

ke

Is the coefficient dependent on the ratio between the column dimensions in direction of eccentricity of bending moments MEd,x and MEd,y.

W,i

is modulus of i-th control perimeter in direction of eccentricities of bending moments MEd,x and MEd,y.

The orientation of axis’s in LCS for punching is always transformed to the first quadrant of GCS of the project and the LCS for punching can be presented in single check, see picture below

Member check

The numerical output can be presented after clicking on action button Preview in service Punching check (tree Concrete Advanced > Punching ) or after adding the item Punching check to the document

Numerical output in service Punching check

Numerical output in document

There are presented following tables in member check

The β factor and other values, which are used for calculation β factor can be presented in table Check punching shear resistance and design shear reinforcement.

Existing table can be edit via icon Table composer   or via double clicking on the header of the table. The new table can be created via icon Table manager

Single check

The dialog for detailed check of one node (single check) will be opened after clicking on action  button Single check in service Punching check (tree Concrete Advanced > Punching ). The numerical output can be presented in tab-sheet  Design of reinforcement  or in tab-sheet Document setup

The numerical output in single check can be presented directly in the dialog (item Preview) or can be set to the main document (item Document)

There is a special table in Results in critical section, where are presented ( depending on the selected method of calculation β factor ) detailed values, which are used for calculation of β factor
