Once the Calculation Options dialog box is opened for RC beams / columns and the Romanian RC code, the General tab includes additionally the following options:
- possibility to switch on seismic requirements
- columns may be calculated by means of the codified or the iterative method
- possibility to switch on the option for concreting in layers <1.5m.
In the case of the STAS code, in the Calculation Options dialog box the user may switch on the Seismic dispositions option - depending on the plasticity rate:
None (no seismic requirements)
Moderate plasticity (selection of a seismic zone: from A to F)
High plasticity (selection of a seismic zone: from A to F)
Moreover, for the Moderate and High plasticity the user may switch on the option Consider plastic moments for shear. This option allows calculation of a shear force according to the points 5.3.3.2 and 5.3.3.3 of the STAS 10107/0-90 code.
It is also possible to choose a group that a calculated column should belong to:
- group A - columns of seismic structures with significant post-elastic deformations (seismic zones A to E)
- group B - columns of seismic structures which behave in an elastic way when subjected to a seismic load (seismic zones A to E) or columns with significant post-elastic deformations (seismic zone F)
- group C - columns in structures not subjected to a seismic load or columns of seismic structures which behave in an elastic way when subjected to a seismic load (seismic zone F).
After pressing the Advanced button the program opens the Advanced Options dialog box which allows switching on the Shear considered option.
Furthermore, it is possible to select a type of the calculated column: inner, outer, corner.
For each column type different coefficients are assumed.
The user may select a number of stories in a building and a number of a story for which calculations will be performed. It is of importance when evaluating the critical zone length in a column - see section 5.3.4.2.2(10) of the code.
For the STAS code it is allowed for to select a code determining material parameters of steel and concrete (see: Remarks concerning characteristic values of materials for the Romanian code).
In the case of continuous footings it is possible to switch on seismic requirements (as for RC beams).
