RC Frame Design

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

It provides design code checking of regular and arbitrary shaped reinforced concrete decks/beams, piers/columns and piles subject to bending and axial force. Tapering and voided members are supported.

Design checks due to bending with or without axial force can be carried out for reinforced concrete sections at the Ultimate Limit State (ULS) and Serviceability limit states (SLS).

The following design codes are currently supported:

  • EN1992-1:2004 - EN 1992-1-1:2004 +A1 Eurocode 2: Design of concrete structures Part 1-1: General rules and rules for buildings.
  • EN1992-2:2005 - EN1992-2: 2005 Eurocode 2: Design of concrete structures Part 2: Concrete bridges - Design and detailing rules.


Defining reinforcement

  • Define layers of reinforcement by entering rows of table data (cover, allowance for links, number of bars, bar diameter etc.) for each numbered face in a chosen cross-section.
  • Bars are spaced equally, and where bars in different faces are shown to clash, end bars from selected faces may be omitted.
  • Use multiple rows of table data to position bars in multiple layers within a face, or to specify more dense or sparse reinforcement within a layer. Alternating bar arrangements and manual bar placements are also supported.
  • Bar spacing, as used for determination of crack widths, is calculated by considering where each bar, or any bundled bars are with respect to other bars in the section.
  • Specify how individual reinforcement arrangements apply over a length of a line, or over multiple lines that represent a concrete member.

Viewing design results

  • Select results components for individual design checks, and obtain maximum utilisation factors in all, or selected members.
  • View results as Utilisation ratios on a results viewing layer for a selected design code, and active loadcase, load combination or envelope.
  • Produce a tabular summary of design check results for selected members and loadcases, view detailed results and generate interaction diagrams.
  • Save results for use with Microsoft Excel, or add them to a model report, and each time the report is generated the reported design data will be automatically updated to match the current state of the model.

The capacity of the RC frame design module to deal with complex section geometry has been fundamental in allowing us to carry out design checking of the individual members of the structure within a limited timescale.

Its use is straightforward, from the definition of the geometric properties, to the post-processing and viewing of the results. 

Ultimate and serviceability limit state checks can be viewed by either plotting contour maps of the utilization coefficient on members of the structure, or by tabulating all or selected details for members of interest and including that data in a model calculation report.
