Implementation of Swedish Annex for EN 1992

SCIA Engineer v 2013.1 brings implementation of Swedish national annex for EN 1992. The following annexes have been taken into account

  • SS EN 1992-1-1:2005/NA:2010-12
  • SS-EN 1992-1-2:2004/NA:2009-01
  • SS-EN 1992-2:2005/NA:2008-12

Update of concrete material library for NBR code

The material library includes several concrete and reinforcement classes specifically according to NBR 6118 and NBR 7480. Generally, there are the following concrete and reinforcement classes:

Import of not-calculated internal forces

New possibility for import of not-calculated internal forces has been implemented in SCIA Engineer v 2013.1. Generally, these forces are not calculated by FEM analysis. A not-calculated internal force is a special option for input of calculated internal forces from the different models together. Typically, when the concrete bridge is analyzed in Frame XYZ, then torsional moments are obtained. Afterwards TDA calculation is available only for Frame XZ. Therefore, the effect of torsion is applied via Not-calculated internal forces on Frame XZ for check of principal stresses.

Not calculated internal forces are accessible in Load > Not calculated internal forces. There are several types of distribution of not calculated internal forces. The import is available for Distribution > Polynomial only.

Import of not calculated internal forces uses the CSV file format. The values in the file are separated by a semicolon. The first value is the position (m); the second value is the forces in the basic unit (N).

Type Interaction diagram check method for particular member

SCIA Engineer v 2013.1 brings possibility to set interaction diagram check method for particular member directly in Member data. Each 1D concrete member in project can has its own check method attached. The advantage is the possibility to set different methods for members in frame corners – one for the beam and another for the column.

Defaults for members are following

  • Beam – Mu – check with a constant value of the normal force
  • Column – Nu – check with a constant value of the bending moment
  • Beam as slab - Mu – check with a constant value of the normal force

Extreme Value versus Extreme Check Value

The new combo Type of values was added to services Prestress check response and Prestress check capacity under the combo box Values. This new combo contains two options:

  • Extreme value (as default) - the selected value will be presented in the graphical window and the extreme value in the numerical output will be based on the maximum check value of the selected value
  • Extreme check value - the check of selected value will be presented in the graphical window and the extreme value in numerical output will be based on the maximum check value of the selected value
