Design steel strength (yield strength)
Number of lateral bracing restraints along the span:
Steel grade: See Note 1 below.
Grades from Table C5: hot-rolled profiles except of type K, SH, and B of I section beams (See Note 2 below)
Grades from Table C3: sheets, wide strips, plates, pipes, and tubes
Grades from Table C4: I-beams with parallel flange faces, type K, SH, and B
Indication of stress strain state per Cl 4.2.7:
The engineer shall consider the appropriate class of the member, as it is used in multiple checks under Ch.8. for elastic or elastic-plastic calculation for bending members (non-axially compressed or tensioned): Cl 8.2.1, Cl. 8.2.3, Cl. 8.4.1, Cl. 8.4.4, and Cl 8.4.6.
- It is common practice to design only Russian or European shapes to the Russian steel codes. For Russian steel sections, the steel design strength value, Ry, is obtained from Tables C.3, C.4, and C.5 of SP 16.13330.2017 determined by the assigned the SGR parameter. For European sections, the ENSGR should be used instead. If steel sections from other countries are used, the PY parameter should be used to specify the steel strength.
SGR parameter values marked with an "*" are from Table C.5. These grades are also repeated in Table C.3 with different labels.
