It is important to keep your software up to date so that you get the latest updates, enhancements and bug fixes. The key changes made to SPACE GASS in recent years are described below. Note that minor enhancements and bug fixes are not listed.
This is a significant new version that contains a number of new modules and features, including the following significant ones:
This is a major new version that contains many new features, including the following significant ones:
Load case numbers are now shown with all node and member maximums and minimums. You can also report the matching coincident values that occur at the same location and load case as each maximum and minimum.
Finally, you can obtain a summary envelope showing the maximums and minimums for a group of nodes and/or members. The summary report also shows the load case numbers and the matching coincident values.
By default, envelope reports include an envelope summary at the end, however you can limit your report to just the summary by checking the box marked "Produce Envelope Summary Only" in the report generation dialogue.
This module is not a standard feature and must be purchased before it can be used. However, if not purchased, you can still access and operate it in a mode that restricts you to a pre-defined column shape. All other features are fully enabled.
Features of the concrete column design module include:
Note that previously, in the absence of self weight or other transverse loads within the segment, any transverse loads at the segments ends were ignored when calculating kl.
The first two paragraphs in section 10.12.9 of the SPACE GASS reference manual should be replaced with:
"The load height factor kl relates to the point of application of gravity loads. It is always 1.0 if the loads are applied at or below the member's shear centre. It can, however, exceed 1.0 if the top flange is loaded with a downwards load causing a destabilizing effect.
If the top flange is loaded within the segment then kl = 1.2 for all codes, except AS4100 and NZS3404 where kl = 1.4 if both ends of the segment are fully, partially or laterally restrained or kl = 2.0 if either end is unrestrained.
If the top flange is not loaded within the segment and shear force is detected at a segment end that is unrestrained then kl = 1.2 for all codes, except AS4100 and NZS3404 where kl = 2.0.
For all codes, kl = 1.0 if the load height position is specified as "C". If the load height position is specified as "T" then all transverse loads (including self weight) are considered to be acting at the top flange."
