Member Design - Member Details
This step defines the member: the design standard, the section, the member length and its segments, and the restraint of each segment.
a. Member input source
Manual: Enter the member properties and forces yourself.
Analysis output (SAP2000 / ETABS / SPACE GASS): Import members and their forces from an analysis export - see Importing from an analysis model below.
b. Member properties
Reference Standard: NZS 3404 or AS 4100.
Member Category: NZS 3404 only (hidden for AS 4100). Select Category 1 to 4; the section geometry is checked against the slenderness limits of that category (Table 12.5).
Member Length (mm): The total length of the member.
Segment Number: 1 for a single segment, or the number of segments of a multi-segment member. The segment table updates to match.
Section Type: New Zealand and Australian sections:
UB (Universal Beam), UC (Universal Column), PFC (Parallel Flange Channel) and TFB (Tapered Flange Beam) - Grades G300+ and G350
CHS (Circular Hollow Section) - Grades G250 and G350
RHS and SHS (Rectangular and Square Hollow Sections) - Grades G350 and G450
CWB (Custom Welded Beam) - user-defined dimensions in various grades
Steel Grade: The grades available for the selected section type.
Section: Select the section from the list for the chosen section type.
For CWB sections, enter the start and end depths (a tapered member when they differ), the flange width and the flange and web thicknesses.
Then select the critical section of each segment:
For Mbx: maximum moment-to-depth ratio, minimum depth, middle depth or maximum depth.
For Nc: middle depth or minimum depth.
The Member Visualization shows the member, its depth along the length and the segment boundaries.
c. Segment Configuration Table
One row per segment; each segment can have its own restraints and lengths.
Seg No.: Segment number.
Start (mm): Distance of the segment start from the start of the member.
End (mm): Position of the segment end. It must be greater than the start and not less than the end of the previous segment.
Restraint: End restraints as per Clause 5.4.3 of NZS 3404 / AS 4100. Start and end are not distinguished; each segment is treated independently.
FF: Full restraint at both ends
FL: Full restraint at one end, lateral restraint at the other
LL: Lateral restraint at both ends
FU: Full restraint and unrestrained ends
FP: Full and partial restraint
PL: Partial and lateral restraint
PU: Partial restraint and unrestrained ends
PP: Partial restraint at both ends
Major Axial Length (mm): Length for buckling about the major axis (x-x). Defaults to the member length.
Minor Axial Length (mm): Length for buckling about the minor axis (y-y). Defaults to the segment length.
Holes Area (mm2): Total area of the holes within the segment.
Start / End Restraint Rotational: "Free" or "Fixed" per Clause 5.4.3.4; sets the rotational restraint factor kr.
Kt: Twist restraint factor. Calculated automatically; not editable.
Kr: Rotational restraint factor. Calculated automatically; not editable.
Kl: Load height factor. Press the ... button next to it to open the load height factor panel: choose the load height position (top flange or shear centre) and, for the restraint types where it applies, the longitudinal position (within the segment or at the segment end). Apply sets it for the segment; Apply to all segments sets it for every segment.
d. Importing from an analysis model
Select Analysis output (SAP2000 / ETABS / SPACE GASS) to design members straight from an analysis export.
Export the model with its member-force results, in kN and m. SAP2000 exports (.s2k or CSI-style .txt tables) and saved StructUpro .json files can be imported, up to 150 MB. ETABS results need to be converted to the same CSI table format first. The SAP2000 and ETABS export guide lists the tables to include.
Choose the file and press Import. The status line reports how many members were imported.
Select the Imported member (frame). Its length (as one segment), its section (when it matches a catalogue section) and its forces are filled in; check them, then set the segments and restraints as usual.
On the Forces step, choose the load combinations for the design (see Forces).
Each imported member keeps its own inputs and results, so you can switch between members and design them one by one. Importing another file replaces the model and clears its member designs - save the project first to keep them.
Access: Importing an analysis model requires an active paid subscription or a Student licence; trial accounts cannot upload analysis files.
Member Design - Forces
The design actions can be entered in two ways. Select the Force Input Method:
Automatic Calculation: Enter the forces at stations along the member, wherever the segments are. The forces of each segment and its βm values are calculated automatically. Best for members with several segments.
Manual for Each Segment: Enter the design forces, αm and βm of each segment directly. Best when you already have the forces per segment.
Method 1: Automatic Calculation
Force Station Number: The number of force stations (2 to 50). It does not have to match the number of segments; use as many stations as the force diagrams need - most analysis programs report forces at stations along each member.
No.: The station number.
Station (mm): The position of the station from the start of the member. Each station must be beyond the previous one, up to the member length.
Mx* (kN.m): The design bending moment about the major (x) axis. Can be negative.
My* (kN.m): The design bending moment about the minor (y) axis. Can be negative.
Vx* (kN): The design shear force. Enter a positive value.
N* (kN): The design axial force, as a positive value; choose compression or tension next to it.
Diagrams: The moment, shear and axial force diagrams are drawn from the stations so you can check the input.
Imported analysis loads
For an imported member, an Imported analysis loads panel lists the load cases and combinations of the model:
Combinations for design (envelope): Move combinations from the List of Load Combinations to the Design Load Combinations with Add -> and <- Remove. The member is designed for the envelope of the selected combinations.
Case / combination for diagrams: Selects the result that fills the station table and the force diagrams.
Method 2: Manual for Each Segment
Segment: The segment number.
Mx* (kN.m): The design bending moment about the major (x) axis. Can be negative.
My* (kN.m): The design bending moment about the minor (y) axis. Can be negative.
Vx* (kN): The design shear force. Enter a positive value.
N* (kN): The design axial force, as a positive value; choose compression or tension next to it.
kte: Correction factor for the distribution of forces in a tension member (Clause 7.3 of NZS 3404 and AS 4100). Active when tension is selected.
αm: The moment modification factor (Clause 5.6.1.1). Press the ... button next to it to open the Moment Modification Factor panel and set it in one of three ways:
Manual input: Enter αm and press Apply.
Based on the moment values - Interpolation between start & end moment: Enter the major axis moments at the start and end of the segment; M2*, M3* and M4* are interpolated and αm is calculated from Eq. 5.6.1.1(2).
Based on the moment values - Input M2*, M3*, M4*: Enter the three moments and αm is calculated from Eq. 5.6.1.1(2).
βm Inplane Major, Inplane Minor and Outplane: The ratio of the smaller to the larger end moment for in-plane major, in-plane minor and out-of-plane bending. Entered manually; used only by the alternative design provisions.
Design: Press Design at the bottom of the Forces step to run the checks. Design needs an active subscription or trial.
Member Design - Results
After Design, the Results step shows the outcome for the whole member and the calculation of each segment.
Critical Segment and Maximum Ratio: The segment with the highest utilisation, its ratio and the check that governs it.
Brief Results for Segments: One row per segment with its lengths, restraint type, kt, kl, kr, effective length, slenderness reduction factor, αm, design actions and ratio.
Result for segment: The calculation of one segment. Use the arrow buttons to move between segments.

Connection design
Overview and design codes
StructUpro designs steel connections to five design codes. Pick a code in the connection catalogue, open a connection and enter its inputs: the 2D and 3D drawings follow your inputs, and the calculation checks the connection to the selected code and writes a full report.
EN 1993-1-8 / UK National Annex / SCI P358 and P398

The connection catalogue
The connection catalogue lists the connections for the selected design code, grouped as simple shear, moment resisting, splices and column bases. Each card shows the 3D model, the design references and a seismic badge for the AISC 341 / 358 options; open a card to go to its design page.
Every connection design page works the same way, whatever the connection or design code. Entering inputs and viewing the drawings is open to everyone; calculation, reports, exports and saved projects need an active subscription or trial.
Open the connection and manage the project
Open the connection from the connection catalogue under the design code you need; the page header shows that code, and the inputs, report and checks follow it. Use Save, New, Load and Save As to keep connection designs as projects.
Enter the inputs, tab by tab
The Design Parameters panel groups the inputs in tabs - typically General (project details and design actions), the members, plates, bolts, welds and the support. Section and material lists follow the design code (for example NZ / Australian, UK and US sections); AISC pages also select LRFD or ASD and US customary or SI units. Validate Inputs checks the geometry and catalogue choices before you calculate. The inputs of each connection are listed in its guide.
Check the 2D and 3D drawings
The drawings redraw as you type. The Elevation and Section drawings show the dimensions, bolt spacing and weld sizes. In the 3D View, drag to rotate, scroll to zoom and right-drag to pan; the 3D, Elevation, Section and Plan buttons reset the camera, and Edges and See-through support change the display.
Calculate and read the design summary
Calculate runs every check of the selected code. The design summary shows whether the design passes, the connection capacity, the governing check and the utilisation, followed by a capacity breakdown of the main checks.
Generate the detailed report
Generate Report opens the full calculation below the form: design parameters, then each check with the code clause, the equations with your numbers and the result. Change an input and calculate again to update it.
Export the report and drawings
Export Report (PDF) saves the detailed calculation report and Export Drawing (PDF) saves the elevation, section and plan drawings with their dimensions. Calculate before exporting: the export uses the last calculated inputs of the selected code.
