Released July 22, 2009 with Design Office 7, Service Release 2
Important Note – These are descriptions to changes implemented in WoodWorks Connections for version 7.2 and may not reflect current program behaviour.
Fixed numerous problems with the Orthogonal and Skewed Lapped Shear connections’ calculations of minimum/maximum end and edge distances, allowable numbers of bolts, rows of bolts, and bolt/row spacings, when overhang offsets are specified other than the default configuration in which the member ends are flush against each other. This resulted in restricted numbers of bolts/rows, incorrectly positioned bolts, and disallowed designs that should be valid.
Connections was incorrectly calculating the end / edge distances, and allowable number of bolts or rows, under some configurations of tension/compression vs acute/obtuse angle of connection.
Connections was sometimes allowing you to specify a number of bolts that would just fit using minimum end/edge distances and spacings, but would report "invalid configuration" when design was invoked, due to small errors in spacing increments.
The number of bolts in a row and the number of rows of bolts for wood to steel lapped shear connection where sometimes restricted to too few .
Orthogonal lapped shear connections loaded in compression where determining minimum end and edge distances incorrectly, sometimes returning distances as if they were loaded in tension. This also affected the number of bolts per row or rows allowed in the connection.
Attempting to design a bolted wood- to-wood lapped shear connection loaded in compression with a specified end distance of 4 x bolt diameter resulted in an "invalid fastener geometry" message, but selecting "unknown" end distance successfully designed using 4 x diameter. This has been corrected.
When determining the maximum number of bolts per row can be fit into a connection a tolerance of 0.5mm is applied. In connections with several bolts per row, this tolerance accumulated and could result in bolts positioned such that their reported end/edge distances are smaller than those used for design, and a failing configuration could be accepted.
In the Moisture Content section of the Load Material view, there were four choices for each of Service and Fabrication condition, with each set of choices redundantly allowing for service and fabrication moisture contents. The selection of Service conditions had no effect on the value of the service condition factor Ksf, and the selection of Fabrication conditions does not create factors in accordance with CSA 086 Table 10.2.1.5. This has been fixed.
The input control for In-Service and Fabrication moisture conditions did not allow enough space for the lengthy strings such as Dry/Unseasoned, to the point that users will not even recognize the words 'seasoned" and "unseasoned". This has been fixed.
In the Bolt Details dialog, the list of allowable end distances shown in the End Distance drop down list was sometimes showing from 8 to 10 diameters instead of 7-10 diameters.
Connections highlighted the selection of purlins in a two-sided connection with different shades of gray, leading users to believe the members and loads entered can be different, when they cannot. Also, "two-sided" was spelled wrong in the title of the output reports, as it was missing the hyphen.
Beam Hanger with Shear Plates in Details view had an unlabelled combo box with no choices. When this box was selected, the help information at the bottom of the Details dialog box showed, "Loaded end distance". This combo box now does not appear for column connections without loaded ends.
Wording "Concrete-to-wood" was changed to "wood–to-concrete" to more accurately describe the connection.
Some design results did not display their results to the number of significant digits that are calculated (e.g. 3 should be 3.000)
