Important Note – These are descriptions to changes implemented in WoodWorks Connections for version 9.3 and may not reflect current program behaviour.
The program applied a minimum perpendicular to grain bolt spacing in row of four bolt diameters instead of the three required by o CSA 086-09 10.4.3.2(a). This has been corrected.
For orthogonal bolted connections, if the main member is not loaded, and the main member width is much smaller than the side member, then the connection design failed with any load. This has been corrected.
For bolted skew connections, when spacing between rows is specified for the side member, the unloaded edge distance on one side became significantly larger than the other, so the bolt array was asymmetric within the side member. The unloaded edge distance should be the same on both sides.
This was an issue only with positioning the fasteners after design and did not affect the edge distance used to determine how many fasteners are possible or, and has been corrected.
concrete connection, that creates a downward load on the fastener group, is incorrectly shown as an upward arrow in both the bitmap image and the beam diagram. This has been corrected on both drawings.
The program is not doing the row shear check from O86 09 10.4.4.4 , for sloped beam-to-beam connections despite the fact this check should be done whenever there is a parallel to grain component.
However, it is unclear at present how to define rows for this equation because neither the rows nor the fasteners in the rows are oriented in the direction of the grain. A design note has been added explaining that this check is not done.
In addition, the program was using Qr rather than the expression including Qr and Pr in the equation for angle to the grain brittle failure mode in 12.4.4.2 (d), and comparing to Nf, which is not correct. If Pr is not calculated, then brittle Nr should not be calculated either. This check has been removed for sloped beam connections.
For a bolted skew connection, a positive side member overhang can be increased so that it causes the program to report that the connection is too small to accommodate even one fastener, even though it could do so with a smaller overhang. Several errors contributed to this problem, such that it is likely that there were other problems with the calculation of possible configurations within this connection. These problems have been corrected.
For lapped shear connections, if the area of intersection between members is too small to allow even one nail of any size, or If the thickness of the members does not allow for minimum penetration, the program reported an Internal Error message instead of an informative error message.
The messages that now appear are as follows:
Current set of fastener selections is not valid
Nails not available because a member is not wide enough to satisfy minimum edge distance and spacing:
Invalid Method
Nails not available because a member is not wide enough to satisfy minimum edge distances.
Nails cannot be used with the current set of main and/or side member selections
Nails are not available because the side member is too thick to allow the largest available nail to penetrate the main member.
The penetration depth used for bearing length in main member for lag screw lateral and withdrawal resistance subtracts 1/2 the tip length from the main member, when according to 10.6.3.1 for lateral loading and Wood Design Manual Table 7.15 for withdrawal loading, the full tip length should be subtracted.. This has been corrected.
For particular sequences of user operations the lapped skew connection failed to design and showed an Internal Error on the input screen. This happened intermittently, and has been corrected.
A positive load on the perpendicular wood to concrete connection, that creates a downward load on the fastener group, is incorrectly shown as an upward arrow in both the bitmap image and the beam diagram. This has been corrected on both drawings.
Starting with version 8.4, for bolted ledger connections, the input field for Penetration Depth was displayed as Width. This has been corrected.
The dimension lines for the main plate in the diagram of the column-to-base connection were showing the width of the plate instead of the height. This happened for all fastener types and has been corrected.
In both the Key code Registration box and the Help About box, we have
Where parentheses were used in the Help About, the closing parenthesis appeared inverted at the start of the line instead of where it should have been. These occurred around things like the date of publication and the relevant parts of design code publications, and have been replaced with a dash as a means of delineating them.
