Software for Structural Engineers

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.

Everything shown on this website is included in the SCALE system.
SAND inclues everything on this website with the addition of non-linear analysis.

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 below.

SCALE is used in over 2000 firms in 35 countries. 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.

Sample output.

For an easy-to-print list of all the proformas, including sample output calculations and detailing drawings for nearly 100 of the proformas, please download or open the pdf file below. This pdf file contains internal links to allow you to navigate directly to each sample calculation. This pdf file was created directly by SCALE, the feature of saving to pdf allows you to transmit calculations to clients and checkers which may be viewed and printed from any computer.

scale.pdf - 274 pages, 1.2MB.

If required, the free Adobe Acrobat Reader can be downloaded from here. The current list of SCALE programs follows.
