New features

The key new features added recently are as follows. Note that minor new features, enhancements and bug fixes are not listed here.

 

Version 12.85

 

The graphics drawing engine has been re-written so that it is now much more responsive and eliminates the problems associated with missed connections when attaching to existing nodes, members or plates.

 

Batch reports let you select from a list of previously saved report configurations and then process them in a batch.

 

Text reports can now be configured and saved for later recall or included in a batch report.

 

The plate meshing engine has been updated so that the meshing tools now generate meshes that contain more well-conditioned quads rather than triangles. This results in less elements and a better conditioned model in general.

 

Added plate cuts that you can draw anywhere across a panel modelled with plate elements to define a cross section through the panel. You can then obtain the forces and moments summed over the cross section.

 

Released a new "Tank Builder" module that can be used to generate a complete flat, domed or Intze tank with or without support structure. The tank builder also generates all of the static and hydrostatic loads, plus wind loads to IS 875 (Part 3) : 2015 and seismic loads to IS 1893 (Part 2) : 2014.

 

Changed some of the "Attachment and alignment preferences" to make attaching to existing members and plates easier.

 

Added colored member contours that show a full color representation of displacements, forces, moments and stresses along members.

 

Added a number of new skins and color pallets that can be accessed via the "Color preferences" configuration.

 

Labels for load and result diagrams can now have their own independent color rather than matching the color of the diagram.

 

Reactions and concentrated loads are now scalable in the graphics window.

 

Reactions can now be displayed for specific directions in the graphics window.

 

Added enveloped analysis result queries.

 

Can now print the graphics to any user specified scale.

 

Can now export from SPACE GASS to StaadPro files.

 

Plate elements can now be included in IFC, StaadPro and Revit imports and exports.

 

The "IFC4.1" and IFC2x3" schemas are now supported in IFC imports and exports. Previously only the "IFC2x3" schema was supported.

 

The "Check connectivity" tool has been substantially expanded to look for extra levels of connectivity, missed connections and separate sub-structures. It can now produce a report that summarizes possible connection issues.

 

Added a "Repeat last action" facility that restarts the last action whenever the Spacebar is pressed.

 

Added an "Invert selection" tool that selects all the items that were not selected and deselects all the items that were selected.

 

Added "Select in-line members" and "Select subdivided members" tools that allow you to quickly select members that lie in a straight line.

 

Added a "Select intersection nodes" tool that allows you to select the nodes where members or plates intersect a plane of plates or where there is a change in direction of members.

 

Added "Select perimeter nodes" and "Select perimeter members" tools that allow you to select the perimeter nodes or members around a plane that is defined by a selection of members or plates.

 

Added a "Load contiguous members" tool that allows you to select multiple members that are connected end-to-end and then load them as if they were just one member.

 

Added a "Varying member distributed loads" tool that allows you to select multiple members and then apply distributed forces that vary linearly or are based on an equation that you can define.

 

A "Find" facility has been added to datasheets for searching for specific text anywhere within a datasheet.

 

Enveloped diagrams of "Absolute maximums" now retain the sign of the maximums rather than setting them all to positive.

 

Recent jobs are now in a "Recent jobs" sub-menu of the File menu which includes a thumbnail image of each recent job and some brief information about it. Up to 50 recent jobs can now be displayed.

 

Value based transparency allows you to see the minimum and maximum values in a plate or member contour diagram more easily.

 

Added a filter option that limits the displayed nodes to just the ones connected to visible members, plates, plate strips and plate cuts.

 

The beep at the end of an analysis can now be turned off in the "General preferences".

 

The shape builder can now import or export coordinates for shapes defined by boundary points.

 

The shape builder can now import a cross section directly from a DXF file.

 

Changed the portal frame builder so that steel member origins are now consistent on both sides of the building so that they start at the bottom for columns and the knee for rafters.

 

Can now do punching shear checks for columns supported on raft footings.

 

Added a new bearing pressure plate contour type for raft footings.

 

Can now specify a filter in the steel member design modules to limit the members being designed/checked.

 

The plate drilling stiffness in static, buckling and dynamic frequency analyses can now be set by the user. In previous version of SPACE GASS it was hardwired to 0.0001 Nmm/rad.

 

For the NZS1170.5 spectral response analysis module, the 0.4s lower minimum imposed on the period for the purposes of calculating kμ for base shear scaling in clause 5.2.1.1 is no longer applied for user-defined periods.

 

The AS3600 reinforced concrete beam and concrete column design modules have now been updated for AS3600:2018.

The IS456 reinforced concrete column module has been updated to automatically calculate effective length k factors based on the stiffness of the interconnecting members.

 

Updated the reinforced concrete slab module to design for torsion as an option. Previously torsion was always considered.

 

Updated the reinforced concrete slab module to design for shear using the general or simplified methods. Previously only the simplified method was available.

 

The pull-out / break-out checks in moment and pinned baseplate connections can now be disabled because they assume an unreinforced footing.

 

Bolted end plate and welded moment connections can now have doubler plates together with top and bottom web stiffeners instead of just allowing one or the other.

 

For bolted end plate and welded moment connections the user can now set the minimum design action as a percentage of ϕMs rather than being hardwired to 50% of ϕMs.

The spectral response analysis module has been updated for AS1170.4-2007 Amendments 1 and 2, NZS1170.5-2004 Amendment 1, IS1893(Part1):2016, IS1893(Part2):2014, IS1893(Part3):2014 and IS1893(Part4):2015.

 

Options have been added to the spectral response analysis module for horizontal base shear scaling based on user specified modes or user defined periods.

 

Base shear scaling has been added as an option to the AS1170.4-2007 spectral response analysis module.

 

An animation controller has been added for when dynamic mode shapes are displayed.

 

Extra script file options are available when exporting to a file that allow you to specify which types of analysis or design results are included in the export.

 

Load categories have been added that make it easy for you to identify and keep track of your loads independently of load cases.

 

An option has been added to the moving load generator for loads that always stay within the ends of their travel path. This is useful for applications such as travelling overhead cranes that can't move beyond the ends of their crane rail.

 

STD files from StaadPro can now be imported.

 

New plate contour diagrams are now available for plate thickness, pressure loads, thermal loads, Wood-Armer adjusted moments and local/global displacements.

Version 12.50

 

This is a major new version containing a significant number of enhancements and new features. SPACE GASS now also supports hardware acceleration in all modern graphics cards. Previously this was restricted to some NVIDIA graphics cards. For more information on this and how to optimize SPACE GASS for maximum performance refer to www.spacegass.com/hardware.

 

Version 12.27

 

Includes a new moving loads tool that allows for stationary and moving loads in the form of vehicles, pressure patches and line loads. Loads can now be applied to plates as well as members, plus a proximity distance setting lets you model multi-level roadways with different loads on each level.

Added copy/paste and import/export facilities to the filter management form.

 

Version 12.24

 

A new reinforced concrete column design module has been added.

 

Version 12.23

 

Support for Revit 2016 has been added.

 

Version 12.20

 

This is a semi-major upgrade that includes many changes, enhancements and fixes. It is also the first version that has all of the tools of the traditional SPACE GASS window now available in the renderer (along with many new tools that are only available in the renderer).

 

A new reinforced concrete beam design module has been added.

 

Tools for querying and viewing steel member design results have been added to the renderer. You can also label the steel member number, load factor and governing load case on each steel member in the model.

 

A load case title column has been added to the combination load cases datasheet.

 

Seismic checks in accordance with chapter 12 of NZS3404 have been added to the steel member design module. The clauses checked are table 12.4(1), table 12.4(3), 12.4.1.2, 12.5.2, 12.5.3.1, table 12.5, 12.7.2.1, 12.8.3.1(a), 12.8.3.1(b), 12.8.3.1(c) and 12.10.3.1.

 

Version 12.00

 

This is a major upgrade containing many new features and substantial performance improvements, especially in the analysis solvers and graphics engine. It also makes the renderer the main interface for the program.

 

Introduced a new "Paradise" solver for the static, buckling and dynamic frequency analysis modules. It is a sparse matrix solver that fully utilizes the parallel processing capabilities of modern multi-core CPUs. The new solver is usually between 10 and 100 times faster than SPACE GASS 11. The most dramatic speed savings occur with jobs that have a large matrix frontwidth and lots of load cases.

 

The renderer graphics now fully utilizes the parallel processors on the graphics card rather than doing the graphics calculations on the main CPU. This means that deflection diagrams, bending moment diagrams, shear force diagrams, etc. can be scaled up and down smoothly regardless of the size of the job, even in fully rendered 3D mode.

 

The renderer has been given a major overhaul with a new user interface that now has almost all of the functionality of the traditional SPACE GASS window. This means that you can do everything in the renderer without constantly having to switch back to the traditional SPACE GASS window. The new functionality in the renderer includes:

 

 

Version 11.09

 

Released an all new Steel Connection Design module for AS4100 that complies with the latest ASI design guides.

 

Released a new Steel Member Design module for AS4600 that works with the cold formed sections from manufacturer including Lysaght, Stramit, Duragal and others. Supported sections include Cees, Zeds, angles, tophats, channels, back-to-back Cees, CHSs, SHSs and RHSs. New cold formed section libraries for Lysaght, Stramit and Duragal have also been included.

 

The Portal frame builder now automatically creates all of the main connections in the building. They can then be used in the steel connection design module.

 

Allow a steel member design to be performed via a script file with the user being able to control the design groups, sections properties and load cases considered.

 

Allow exporting of steel member design/check summaries to a text file or MS-Excel/Access/Word file.

 

Version 11.08

 

Various new script commands have been added that allow you to have more control over importing/exporting and analysis. You can also pause the script to see what stage it is up to at any point.

 

Version 11.05

 

Released a Portal Frame Builder module for the modelling of portal frame buildings in SPACE GASS. It generates the full structural model plus dead loads, live loads, wind loads and steel member design data. The module supports gable (symmetrical and asymmetrical) and monoslope roofs, overhangs, knee braces, haunches, fly bracing, uneven frame spacings, openings, roof/wall bracing and end wall props. Wind loads are generated in accordance with AS/NZS 1170.2:2011 for all regions in Australia and New Zealand.

 

Version 11.01

 

Released a Sea Load module for the calculation of wave, current, marine growth and buoyancy loads on submerged structures in marine and offshore environments.

 

Version 11.00

 

This is a major new version that includes a new 3D renderer with full editing capabilities. Of course you can still edit your model in the traditional SPACE GASS window, however the editing tools in the renderer are generally more advanced and offer additional features over the traditional editing tools.

 

Some of the load input tools, design data tools and analysis results diagrams are not yet available in the renderer, however they will be added soon.

 

Member force and moment envelope reports can now be limited to the maximum and minimum values taken from just one end of the members rather than from both ends.

 

The analysis engine has also had a major make-over with finite and large displacement theory added, plus options for secant or tangent matrix solutions, residual or full loading, and residual convergence criteria. An "Auto" optimizer setting has also been added that senses the most efficient optimization method before the main analysis calculations begin. It removes the necessity for you to manually use trial and error methods to find the best optimization setting.

 

The standard libraries have been completely re-designed allowing non-standard and built-up sections to be saved. A new shape builder, moving loads generator with animated moving loads, and area loads generator have also been added.

 

Other major new features include on-screen notes, job attachments, dimensions, load combinations grid, load case titles viewer, measure tool, textures, gridlines, view selector, customizable toolbars and multiple undo/redo steps.
