Analysis and design to Australian Standards 5100:2017 (2nd Edition).
This release maintains the superseded AS 5100:2004 and has the ability
to convert between editions.
Significant changes to the 2004 edition of AS 5100.5 include the design of
flexural members for shear and torsion, incorporating the modified compression field theory.
For details of other changes refer to the preface in the Standards.
-
Canadian precast sections added.
-
Mixed beam type linebeam models.
Dead load and deflection analysis can now be performed for mixed beam
linebeam models. If the linebeam contains both composite steel and concrete beam types, set the
continuity for the concrete type. The composite steel type will be continuous from girder only.
-
Pre-tensioned prestressed beam analysis.
Non-prestressed reinforcement can be optionally included in the calculation
of cross sectional properties of the non-composite section via a new check box on the design beam analysis
form. The default is to exclude reinforcement for legacy files and to include for new beams.
For Eurocodes shear analysis, it is now possible to override
the effective depth value on the section definition form. The results detail the default value calculation.

AASHTO LRFD - Design Section Service Limit State.
The following options are added for the control of cracking calculations:
Apply 2" concrete cover limit.
Apply 5" reinforcement spacing limit.
-
Australian Standards 5100 - stress-strain curve for reinforcement.
The default ULS stress-strain curve for reinforcement has changed for Australian
Standards. The new default gives identical yield stress in tension and compression with 500 MPa at
0.25% strain. The previous default has been migrated to a curve option labeled "BS 5400", which is
based upon the ULS stress strain curve defined in the UK Bridge Design code BS 5400.

Creep calculation for long term elastic modulus in SLS Design Section analysis.
Additional detail has been added to the Design Section creep calculations
for "drying shrinkage for age at first loading" and "age at time" according to EN1992-2. These two age
parameters are added to the "Design Data for Serviceability Calculations" form. The parameter formerly
labeled as "Age at loading" has been renamed as "Age of concrete". The effect of ambient temperature
on creep has been corrected.
-
Design Section concrete elastic modulus interpolation.
The Design Section Service Limit State now has an alternate option for
interpolating elastic modulus. The calculation of the interpolated value is detailed in the results.
