About Structural Toolkit V5.7.0.2 (64 bit)

Corrected Timber Notch summary units.

About Structural Toolkit V5.7.0.1 (64 bit)

This update incorporates integrity reinforcement for concrete punching along with other minor corrections and improvements.

About Structural Toolkit V5.7 (64 bit)

This update incorporates a new trial and educational file formats, adds lamination status to timber members in the summary, adds support for custom steel section densities, and the ability to convert a roof or floor beam to a linked member analysis/design along with other minor corrections and improvements.

About Structural Toolkit V5.6 (64 bit)

This is a major update which includes member snapshots (multiple designs within a single member design); improvements to comments including dynamic updating for comments attached to cell formulas; new timber joints modules; concrete member reinforcement design (linked to member analysis or imported from Analysis Standard); incorporation of complete analytic solution for eccentric pads and footings (eccentric pads, pad footing, retaining walls); incorporation of amendment 1 (and improvement to construction and in-service loading utilising snapshots) to the composite module; several new timber types in the timber library; refinement of timber categories in the timber design modules; update to the cleat module for copes; checksums to the haunch design; and more...

In the Analysis Standard a new Query function has been added to find maximums including comprehensive filters; a new arc function; ability to add member restraints; additional member alpha support; create timber, steel and concrete member designs directly from the Analysis using the results and segments (with automatic alpha m calculation for steel design); create linked anaysis designs for timber, steel and concrete members directly from the Analysis; create end plate, apex/ridge, haunch and portal knee designs directly from the analysis; and more...

About Structural Toolkit V5.5.5.0 (32 bit)

This update incorporates a minor warning the Detention when tc < tcs and an optimisation of the Analysis viewer during panning and rotation resulting in a speed increase along with some some other minor analysis viewer corrections.

About Structural Toolkit V5.5 (32 bit)

This major update includes support for the AS2327-2017 Composite Structures (simple beams), AS3600-2018 Concrete Structures amendment 2, AS1170.2-2021 Wind Actions, Australian Rainfall and Runoff (ARR) 2019 AEP method for rainfall intensity, double span steel roof and floor beams added Smart LVL 13 timber grade and more. Multiple module Preset features have been added, and there has been significant interface updates to add new dark and light modes. Analysis frame wizards have been added, the analysis view has been updated, additional print view features including automatic print view setups have been added, a new member length feature added to adjust the length of members, and analysis printouts refined to match the scale of Structural Toolkit printouts. We also have new learning documents for the composite, concrete, wind and ARR changes. The .NET framework platform has been updated from 4.6 to 4.8. And lots more...

About Structural Toolkit V5.4 (32 bit)

This major updated includes support for AS3600-2018 Concrete Structures as well as a number of minor updates to modules. A problem with slow panning in the Analysis Viewer (on some systems) has also been addressed. And lots more...

About Structural Toolkit V5.3 (32 bit)

The .NET framework platform has been updated from 4.0 to 4.6 as well as a number of framework components meaning that XP is no longer supported. There are also minor program improvements including a correction to reactions from unopened linked analysis members and several module updates.

About Structural Toolkit V5.2 (32 bit)

Version V5.2 introduces the ability to apply reactions from other floor and roof members (See the tutorial in the Learning Centre), refinements to the Concrete Column FRP and addition of quasi-dead case for timber (refer appendix G1), linked Timber Member analysis dead combination check, as well as other minor refinements and fixes. The Analysis has received some improvements to the move functionality and some other minor interface improvements and corrections.

About Structural Toolkit V5.1 (32 bit)

Version 5.1 introduces an extensive update to the Timber Library incorporating 20 additional timber selections (including Hyne, Unilam, LP Building Products, Smart LVL, SolidStart LVL and formwork products); timber service class and variable J2 for certain timber sections; new Steel Library incorporating revisions to the Steel Iw and J properties for PFC's from the OneSteel Edition 7 and associated amended Steel Properties module reflecting changes; Custom Steel sections have E and G definable; auto Page Numbering of Exported Projects; modification to shear capacity of RHS/SHS sections including non-uniform shear; smoother Preview and PDF measuring; and in the Analysis improved corrections (including not allowing Linear Analysis corrections); fixed the sign of the local intermediate rotations; and also corrected intermediate unform axial load deflections and intermediate global rotational displacements for pin ended members.
