D13.E.5 Member Selection and Code Check
Both code checking and member selection options are available in SP 16.13330.2017.
Output of selection and check results are given in suppressed, extended and advanced forms. Form of output results depends on value of parameter TRACK.
Results are presented in tables. Three versions of output results are possible: suppressed – results according the critical strength condition (TRACK=0), extended - results according to all check conditions (TRACK=1) and advanced – complete information on results of member design (TRACK=2).
- (TRACK=2)
- number of member;
- type and number of cross-section;
- result obtained (ACCEPTED – requirements are met, FAILURE – are not met);
- abbreviated name of normative document (code, standard) (SNiP);
- number of check clause;
- safety of strength (ratio between design and normative values);
- number of the most unfavorable loading;
- value of longitudinal force acting in the member with subscript indicating its direction ("C" – compression, "T" – tension);
- bending moments in relation to local member axes Z and Y;
- distance to section, in which the most unfavorable combination of forces acts.
Refer to D1.B.1.3 Code Checking for general information on Code Checking. Refer to TR.49 Code Checking Specification for details the specification of the Code Checking command.
Refer to D1.B.1.4 Member Selection for general information on Member Selection. Refer to TR.49.1 Member Selection Specification for details the specification of the Member Selection command.
D13.E.5.1 Example of TRACK 0 output
In suppressed form (TRACK 0) results are presented according to the critical check for given member with indication of SP 16 clause number, according to which strength safety of the member is minimum.

Conventional notations assumed in presentation of results: "+", "-", "/", "*","**", "SQRT", their respective meanings (i.e., addition, subtraction, division, multiplication, raising to the second power (squared), and square root). Conventional notations of stresses, coefficients and characteristics of steel resistance comply with accepted in the SP standard. Only Greek letters are changed by their names (e.g., , γc-GAMAC; α-ALPHA; β-BETA, η-ETA, φ-PHI, etc.).
