Dimensioning

The "Dimensioning" frame serves to design and verify the reinforcement of abutment cross-section – the cross-section subjected to dimensioning is selected in the combo list. The table shows the abutment forces.

Offer of cross-sections that can be verified depends on the selected load case (construction, service). The following cross-sections are available for both the construction and service state:

Wall stem verification
Construction joint verification	depth of construction joint from construction top edge is specified
Wall jump verification

The service state makes also possible to verify:

Verification of closure wall
Verification wing - abutment	the surface surcharge due to terrain is inputted, for actual analysis we refer to section "Wings"

The frame appearance is adjusted based on the selected verification methodology.

Classical analysis – the column F in the table allows for inputting the design coefficients, which multiply the calculated forces. These forces are displayed on the desktop and are updated for every change of data and setting in the frame.

Analysis according to EN 1997 – the column G in the table allows for specifying whether the loading acting on a structure is considered as a secondary one. This is explained in more detail in section Load combinations.

Analysis according to LRFD – in the case that column F is not displayed.

The abutment is loaded either by active pressure or pressure at rest depending on the input specified in the frame "Settings", an active earth pressure is used when analyzing wing walls. 

The procedure to derive distribution of internal forces in individual cross-sections is described in the theoretical part of this hint.

Dimensioning of the steel-reinforced concrete structure is performed according to the standard set in the frame "Analysis methods". Verification analysis based on the standard CSN 73 6206 "Design of concrete and steel reinforced concrete bridge structures" is described herein.

Several computations for various cross-sections can be carried out. Various design coefficients of individual forces can also be specified. The resulting forces are displayed on the desktop and are updated with an arbitrary change in data or setting specified in the frame. The "In detail" button opens the dialog window that contains detailed listing of the dimensioning results.

Visualization of results can be adjusted in the "Visualization style settings" dialog window.
