D11.A.5.1 Analytical Member Design
Thirteen equidistant cross-sections including two end sections are selected from an analytical member. For each cross-section, the member resistance checks are evaluated for each load case. The design inputs (except forces and section properties) are treated same for throughout the length of the member.
For analytical member design, by default the member is divided at 13 evenly spaced points along the member length.
The default sections for design when BEAM 1.0 is used
| Automated Design Calculations | PMEMBER Design Parameter | Comments |
|---|---|---|
| αb compression member section constant per NZS3404 6.3.3. | n/a | Calculated from table 6.3.3. |
| αm moment modification factor per NZS3404 5.6.1.1 or Table 5.6.2 depending on if the segment is restrained at on/both ends. | ALM | Calculated based on moments distribution for individual segments and sub-segments. |
| fu tensile strength per NZS3404 2.1.2 and AS4100 table 2.1. | FU | Based on nominal steel grade specified using SGR design parameter and element thickness. |
| fy yield stress per NZS3404 2.1.1 and AS4100 table 2.1. | FYLD | Based on nominal steel grade specified using SGR design parameter and element thickness. |
| Residual stress category for NZS3404 Table 5.2 and 6.2.4. | IST | Based on section type. |
