Design code facilities

Two software options allow for design checking of members in steel and reinforced concrete frames.

Steel Frame Design

The Steel Frame Design software option provides full details of all calculations made, referencing all relevant clauses and equations from a design code, and gives a step-by-step calculation transparency normally only found in simple frame analysis software.

Results are viewed as Utilisation ratios on the model, or as a tabular summary for selected members and loadcases. 

When added to a model report, results are automatically updated each time a report is generated to match the current state of the model.

The following design codes are currently supported:

  • AASHTO LRFD 7th Edition (2014)
  • AASHTO LRFD 8th Edition (2017) 
  • CSA S6-14 Canadian Highway Bridge Design Code
  • EN1993-1-1+A1:2014
  • EN1993-2: 2006

with more being added with each release.

A tabular summary of design check results can be produced for selected members and loadcases. Results may be saved for use with Microsoft Excel or saved to a text format. Results can also be added to a model report, and each time the main report is generated the design summary data will be updated to match the current state of the model.

To investigate the design calculations carried out for particular members, formatted design reports can be generated, showing the calculations made and referencing clauses and equations from the code. A formatted design report for the selected member can be added to a model report.


RC Frame Design

The RC Frame Design software option carries out checking of reinforced concrete members subject to bending and axial force at Ultimate Limit State (ULS) and Serviceability limit states (SLS). Regular, arbitrary shaped, tapering and voided members are supported. Layers of reinforcement are defined for each cross-section along with how individual reinforcement arrangements apply over the lengths of lines representing concrete members.

Results are viewed as Utilisation ratios on the model, or as a tabular summary that allows drilling-down into detailed results and creation of interaction diagrams for selected members and locations. Results can be added to a report and are automatically updated each time a report is generated to match the current state of the model.

Design codes currently supported:

  • EN1992-1:2004
  • EN1992-2:2005

with more being added with each release.


RC slab / wall design

The LUSAS RC slab / wall design facility is for use with reinforced concrete slabs (without prestressing) that are modelled using plate or shell elements. It enables contours and values that indicate flexural reinforcement requirements at Ultimate Limit State (ULS) to be plotted, and plots design crack widths at Serviceability Limit State (SLS) for those design codes that support this. Codes currently supported include:

  • AASHTO LRFD 7th, 6th, 5th Editions
  • AS5100-5-2004, AS3600-2009
  • BS5400-4, BS8007:1987, BS8110-1:1997 & BS8110-2:1985, BS EN1992-2:2005/NA:2007, BS EN 1992-1-1:2004/NA:2005
  • CAN/CSA S6-06, S6.1-06
  • Eurocode EN1992-1-1 and EN1992-2
  • IRC: 112-2011, IRS: CBC-1997
  • SS CP65: Part 1 and 2: 1999, SS EN1992-1-1/NA 2008 Amd 1.


Concrete creep and shrinkage

Concrete creep and shrinkage is calculated in accordance with:

  • AASHTO LRFD 7th Edition 

  • CEB-FIP Model Code 1990 

  • EN1992-1-1:2004 Eurocode 2 

  • IRC:112-2011

  • User - allows user-defined parameters to be specified


Prestress and post tensioning

Tendon forces are calculated in accordance with:

  • AASHTO LRFD 2nd Edition
  • AASHTO LRFD 5th to 7th Edition
  • BS5400-4:1990
  • DD EN1992-1-1:1992 Eurocode 2
  • EN 1992-1-1:2004 Eurocode 2
  • JTG D62-2004

See Load types and combinations for more information.


Tendon properties

Tendon properties for which prestress calculations will include time dependent effects for any stage of construction include:

  • AASHTO LRFD 5th to 7th Edition

  • EN 1992-1-1:2004 Eurocode

  • IRC:112-2011
