Steel Design

The LUSAS Steel Design option builds upon the renowned modelling and analysis capabilities of LUSAS and extends the engineer’s workflow to allow design code checking of steel members.

In some finite element software systems, sectional design is offered through summary pass/fail checks on a model. Whilst LUSAS offers this, it also provides users with full details of the calculations made, referencing all relevant clauses and equations from a design code - giving a step-by-step calculation transparency normally only found in simple frame analysis software. Full details of the design checks undertaken can also be written to a model report.

The following design codes are currently supported:

  • AASHTO LRFD 7th Edition (2014) - AASHTO LRFD Bridge Design Specifications, 7th Edition, American Association of State Highway and Transportation Officials, 2014.
  • AS 4100-1998 Steel Structures (Australia) - Australian Standard: AS4100-1998, Steel structures, Standards Australia International Ltd, Sydney.
  • CSA S6-14 Canadian Highway Bridge Design Code - CSA-S6-14, Canadian Highway Bridge Design Code, Dec 2014, CSA Group.
  • EN1993-1-1+A1:2014 - EN 1993-1-1:2005 Eurocode 3: Design of steel structures – Part 1-1: General rules and rules for buildings.
  • EN1993-2: 2006 Eurocode 3: Design of steel structures - Part 2: Steel Bridges.


Viewing design results

Design check results are visualised as Utilisation ratios on a results viewing layer for a selected design code, and active loadcase, load combination or envelope. Results components for individual design checks can be chosen for viewing, and maximum utilisation factors can also be obtained.

Design summary reports

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.

Formatted member reports

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.

 


“One of the key benefits that we see in LUSAS’ new steel design capability is the provision of fully-detailed calculation output. This allows us to easily check the steps in the calculation. We are also pleased to see that the facility sits fully inside LUSAS, rather than as an external utility. This means it functions in a familiar way for the engineer as the rest of the modelling process.”

John Harrison, Structural Engineer, Reid International


"The new section checking facility... provides everything the user needs to interrogate and verify the implementation of the design codes, which is a welcome contrast to the ‘black box’ approach of some other software packages."

Ben Curry, Senior Engineer, COWI
