SCALE *** Structural CALculations Ensemble ***

SCALE is a computer program for producing neatly composed pages of structural engineers' calculations and component details for the design of a variety of components such as beams, columns and slabs, using steel, concrete, masonry and timber.

SCALE incorporates a library of nearly 1000 proforma calculations, any of which may be selected for use when SCALE is run. The content of this library is continually under review, proformas being added or modified as codes of practice develop and change.

SCALE includes LUCID for reinforced concrete detailing and SPADE for steelwork, masonry and timber detailing. Each program takes the form of a text file - written using a simple notation for control. The engineer may alter or extend any program, or write his/her own and add them into the ensemble. SCALE includes NL-STRESS for 2D/3D elastic analysis with linking between analysis and design.

SCALE itself contains proformas on the following subjects, these are listed in full in the pdf below.

  • Mathematics and Miscellaneous
  • Reinforced Concrete Design to Eurocode 2 and BS8110
  • Reinforced & Prestressed Concrete Design to Eurocode 2, BS5400/DOT
  • Reinforced Concrete: Eurocode 2, BS8007, BS8666, Section Analysis
  • Composite Construction to Eurocode 4, BS5950 and BS5400
  • Timber Design to Eurocode 5 and BS5268
  • Steel Design to Eurocode 3 and BS5400 & DOT
  • Steel Design to Eurocode 3 and BS5950-1:2000
  • Masonry Design to Eurocode 6, BS5628 and MEXE
  • Analysis by NL-STRESS
  • Analysis by Traditional Methods
  • Pre and Post Processors for Structural Analysis
  • Loadings and Foundations
  • Drainage and Surveying

SCALE is used in over 2000 firms. Together the users produce over one million pages of structural calculations per year; SCALE has condensed print and summary options for saving paper.

The output from SCALE is a set of pages, neatly titled, dated and numbered, containing calculations and component details made to a standard suitable for submission to a checking authority.

All proformas have now been modified such that each proforma will allow design to the previous British Standard showing full workings displayed to the British Standard, or design to the new Eurocode with full working displayed to the Eurocode. The user can choose the code at the start of the proforma and alternate between codes as required.

Sample Word output.

SCALE can now save calculations in Word (docx) format. For sample output calculations, detailing drawings, analysis runs and plots for over 130 runs of SCALE, LUCID, SPADE and NL-STRESS, please download or open the Word file below. This file is built automatically for each update. This Word file contains bookmark links to allow you to navigate directly to each sample calculation. This file was created directly by SCALE - the feature of saving as Word allows you to easily combine calculations into Word documents.

All drawings (NL-PLOT/LUCID/SPADE) are converted and embedded as svg vector graphics files for crisp display and printing and small file size. The drawings display correctly with the latest Word 2019 or Office 365 subscription on Windows and iOS, however they may not display in older versions of Word/OpenOffice/LibreOffice.

scalesamples.docx - approx. 600 pages, 2MB.

Sample pdf output.

For sample output calculations, detailing drawings, analysis runs and plots for over 3000 runs of SCALE, LUCID, SPADE and NL-STRESS, please download or open the pdf file below. This file is built automatically for each update. This pdf file contains bookmark links to allow you to navigate directly to each sample calculation. The pdfs in this file were created directly by SCALE and NL-STRESS, the feature of saving to pdf allows you to transmit calculations to clients and checkers which may be viewed and printed from any computer.

scalesample_all.pdf - approx. 15,000 pages, 52MB.

In addition to producing full sets of calculations, SCALE can also be instantly switched back and forth to produce summary calculations. These typically show a page of output for each calculation. Sample summary calculations are given in the pdf below.

scalesample_summaries.pdf - approx. 4000 pages, 12MB.
