CS 455 calculation sheet (Excel)
cs455_export_calc_sheetUse for the CS 455 Excel calculation sheet of one element end. For EN 1992 use ec2_export_calc_sheet. The report. Assesses one element end exactly as cs455_assess and writes the plugin's reference-format calculation sheet (.xlsx: A4 pages, title block, geometry, materials, reinforcement, section properties, sagging/hogging bending, shear and torsion with live formulas and charts (for a column, pier or pile: effective heights, N_uz, the governing biaxial bending and shear rows and a table of every row), summary of results, and a Summary sheet with demand, resistance and ratio per check). Returns a download link. Use the same rebar/links that cs455_describe_section confirmed against the user's drawing. Read-only on the model.

}Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| fy | No | Reinforcement yield strength, MPa (default 500). | |
| end | No | ||
| fcu | No | Concrete cube strength, MPa (default: from the model's EN grade C../.. — its cube value). | |
| cases | No | Load cases / combinations by name (default: every load combination the model has). | |
| image | No | cs455_describe_section only: return the drawing of the section with its bars (default true). | |
| links | No | Links (omit for concrete-only shear, cl 5.6). Used by shear and by torsion. | |
| rebar | Yes | The bar schedule, as the plugin's Reinforcement tab: cover (mm to the bar face, default 50), gap (mm between layers, default max(25, Ø)), rows [{face: bottom|top|side|depth, layer (any whole number, 1 = outermost), count ('8' bars or '@150' spacing), dia (mm, or '1.128in', or '#9'), depth (mm below top, face 'depth' only), span ('±430:900' width limits), from/to/which (side bars)}], coords {datum: bc|bl|tc, text: 'y z dia' per line, mm}. | |
| shear | No | Run the shear check (default true). | |
| member | No | Assess as a column, pier or pile to CS 455 Section 7 instead of a beam (the plugin's Sections tab > Member). The effective height about each axis is a Table 7.2 case (1: both ends held in position and rotation 0.7; 2: top in position only, bottom fixed 0.85; 3: both ends in position only 1.0; 4: bottom fixed, top unrestrained, racked rollers 1.3; 5: bottom fixed, top unrestrained 1.4; 6: bottom fixed, top restrained in rotation only 1.5; 7: cantilever, top free 2.3) or your own factor k (l_e = k l_o). Give links: their diameter and spacing decide whether the compression bars count (7.6). A pile is assessed as a column with no soil restraint: give k for its depth to fixity. Omit for a beam. | |
| report | No | ||
| element | Yes | ||
| maxRows | No | Stop above this many force rows (default 1000). | |
| torsion | No | Torsion check, CS 455 cl 5.17–5.27, on rows that carry a torque (default true, as in the plugin). | |
| location | No | ||
| stations | No | Element ends to assess (default: the section's first element, both ends, midspan). Location 'support' removes the shear enhancement near supports. | |
| axialSign | No | Positive MIDAS axial is tension (-1, default) or compression (1). | |
| sectionId | Yes | The CIVIL NX section id (a beam section). | |
| momentSign | No | Positive MIDAS My is sagging (1, default) or hogging (-1). | |
| restrained | No | Compression bars are restrained by links (cl 5.3.1). Default false: compression bars get no compressive strength (cl 5.3.2(1)), conservative. | |
| concreteModel | No | Figure 3.4.1 curve (default) or the constant 0.6 fcu/γmc block of cl 5.1(3). | |
| concreteParts | No | Composite sections: { part id: f_cu } where a part's grade differs (describe lists the parts). | |
| tensionOrigin | No | ||
| classification | No | RC only in these tools. | |
| drawingReference | No | ||
| secondaryActions | No | Vy / T / Mz: assess N–My–Vz and list them (default), or refuse rows where they are non-zero. | |
| confirmDimensions | No | Only after the user has compared the drawn section with the drawing: needed when CIVIL NX published no properties to check the outline against. |
