1. 8 Width and Depth Nomenclature Change 19 Version 8 11 The letters b and d for input breadth and depth of the members in a lapped shear connection have been changed to Thickness and Width These designations caused confusion because the b dimension in the usual b x d nomenclature is the d dimension for connection design The post and beam connections have been renamed Width b and Depth d to make it clear what is meant by b and d which are shown in the pictures identifying some of these connections 9 Default Member Names The following problems have been corrected pertaining to the default values for new files of member names that you can assign to the main and side members a Incorrect Member Names Bug 2379 For version 8 the default member names that appear in the main and side member input for some member types are not the same ones that appeared in the diagram in previous versions of the program and do not correctly identify the member For example they sometimes identify a column as a girder b Update of Names Bug 2379 The program did not update a change in member name when switching from main member tab to side member and vise versa When returning to the main member the old name was still there c Ledger Board Name Change 16 The member name Ledge has been changed to Ledger board 10 DXF Export Activation Bug 2364 Starting with version 8 the program no longer disabled the DXF export button for those connect2. b Minimum of Spacing and End Distance Value for Group and Row Checks Bug 2394 When the main member is the only one loaded in the orthogonal lapped shear connection the program was not using the minimum of row spacing and end distance to calculate the value as for row shear resistance and Apgi for group tear out resistance instead just using the row spacing This created in non conservative resistance values when the end distance was less than the row spacing c Group and Row Checks for Extended End Lapped Shear Connections with One Bolt Per Row Bug 2408 When there is just one bolt per row on the group tear out and row shear checks for connections with extended end types the program applied a wildly high resistance based on 10 000 mm end distance Now the Group and Row Tear out checks are not applied for these connections d Orthogonal Connection End Distance for Row Shear and Group Tear out Bug 2475 The end distance used for the calculations for bolted row shear resistance 10 4 4 4 and group tear out 10 4 4 5 was the minimum end distance as input in the Details screen rather than the actual end distance designed by the program As a result the row shear and group tear out resistance were almost always underestimated which may causes over design or failure to provide design to resist the applied force when a design exists 6 Side Plate Design for Beam to Column Connections Bug 2462 Version 8 11 For beam to beam and beam t

Connections help file Previous Versions Version 7 2 July 22 2009 Design Office 7 Service Release 2 The following issues have been addressed with this service release 1 Bolted Lapped Shear Connections a Overhang Settings 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 b Skewed Connections 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 c Wood to Steel Connections 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 d Wood to Wood Orthogonal Connection Orthogonal lapped shear connections loaded in compression where determining minimum end and edge distances inco

31. o column connections the program sometimes reports a design failure for the face plate connected to the supporting beam or column when in fact the design passed This happens when there is significant horizontal X direction loading on the supported side member such that the program has to explore connections that require more than the default side plate height which is 35 of the height of the side member B Data Input and Program Operation Most of the following problems were introduced with the reorganization of the program user interface for Version 8 and corrected for 8 1 1 Update of Details Upon Change in Member Dimensions Bug 2402 In version 8 when you returned to the Materials screen to change the member data then returned to the Details all of the limits for the input choices details screen would be refreshed This ensured the design stayed within allowable limits If an input was no longer allowed it was blanked out This system was not perfect but it worked this way most of the time With the materials and connections details now on the same screen the program materials input was no longer triggering an update of the details so that the program could easily get into a state that no design was possible with the fastener input choices The details are now updated upon a change in member dimensions or configuration As the program then redesigns this ensures that a diagram showing a connection design stays in the Details scree
