The following changes have been made to the Wall and Shearline Input form and/or the Openings Input form:
The Shearline input is now disabled if there is no choice other than Auto. This input allows you to select the shearline a wall belongs to if the walls are within the allowable shearline offset of walls defining two or more shearlines. As the default offset in the Design Settings is only 6", this rarely occurs, and the use of this input was unclear to some users.
The input for relative rigidity appearing in Wall Input view when in Standard Wall mode has been removed. You can no longer enter this value when modifying a regular wall, and now serves only to show the rigidity of the designed wall relative to others. It has no meaning for Standard Walls.
A warning message about nail length limitations from an irrelevant design code appeared when the mouse was clicked anywhere in the input form, when Gypsum Wboard 1-ply was selected the sheathing material and Drywall screws, fastener type, with the fastener Size in focus, This has been corrected
The following changes have been made to the inputs of hold-down information.
For perforated walls and for the new force-transfer walls, the Apply hold-downs to openings checkbox in Wall Input form, and all input in the Hold-down data group in the Openings Input form, are now disabled because hold-downs are not placed at wall openings for these types of walls.
The hold-down model input has been changed from an editable drop-list to a noneditable list, as a hold-down typed into this input would not necessarily match with an existing one in the database.
The following changes have made to the Design Settings
The check box for Worst-Case rigid vs flexible diaphragms was disabled and showing as selected if only one of Rigid or Flexible Analysis was selected in the Structure input. Now it is shown as not selected (empty) in this case.
The Moisture conditions did not reset to their original values, 15% for Fabrication and 10% for In-service, when Reset original settings was pressed. This has bene corrected.
The date group Collector forces based on in the Design Settings has been renamed Forces based on , as the definition of Collector in ASCE 11.2 includes drag strut as a synonym, so that hold-downs cannot be considered a "collector" This change has also been reflected in the Design Settings output.
The redundant word "forces" has been removed from the column headers in the data group which now say Hold-downs and Drag struts.
In the SDPWS Deflection Equation data group, the SDPWS reference for the 3-term equation option was 4.2-1, the equation for diaphragms, and has been changed to 4.2-1, the one for shear walls.
The reference for the 4-term equation was listed as C4.3.2-2 , the Commentary reference for 3-term, and has been changed to C4.3.2-1, the correct equation for 4 term.
The references have also been corrected in the Design Settings output table. The correct equations were used in design; this was only a display issue.
The data group Apply height to-width ratio to…has been removed from the Design settings, as it applies only to multi-block low-rise structures, which are not permitted in version 11.2.
Note that Shearwalls 2019 incorporates these structures and includes the setting Low-rise height-to-width limit based on….
The option to ignore the contribution of gypsum-based materials for narrow wall segments is now checked by default, as it is normally advantageous to do this.
Other settings changes:
Sime of the inputs in Wood Properties and Construction Details section of the Hold-down settings were too small to show typical data without scrolling and have been enlarged.
The following settings were not being saved as defaults when Save as default for new files was selected.
This has been corrected.
Fabrication and In-Service Moisture in Design Settings were not being reset to their original value after you reset original settings.
The Snap Increments input in Plan View and Elevation View settings was not being re-enabled if the Display gridlines was not checked before you reset original settings. It is now enabled after the reset because Display gridlines is checked in that case.
The following changes have been made to the Site Information input form
If Site Class F is selected in the Site Information and the Fa and Fv values now show zeroes rather than the values from the last site class selected; and if you exit the dialog without the program now issues a warning message asking you to enter non-zero values. If OK is selected, you return to the input dialog; If Cancel is selected, the changes are reverted.
The link to the wind speed map in the Site Information has been updated to refer to the new web address for the Applied Technology Council’s Hazards by Location website. The previous site expired on June 30, 2018. Note that as of March 21, 2018, it is a beta release of the website
The reference to the seismic maps containing site coefficients S1 and SS in the has been changed from to . The new link is from the SEAOC/OSHPD Seismic Design Maps Tool that is referenced in the web site from the old link, the U.S. Geologic Survey (USGS) Earthquake Hazards site, however it is amongst many other links on that site and it was not clear which one to choose.
In Generate Loads dialog, the following values reverted to their original values after being edited and you clicked anywhere outside the box before generating loads:
Seismic loads:
Wind loads:
The program now retains all the inputs.
The choice of using low-rise side panel coefficients or using ASCE -7 Fig. C28.3-2 was sometimes disabled even when there were hip roof panels on the structure. This has been corrected.
A note to enter a mass with negative magnitude to represent an opening in the floor now appears at the bottom of the Add a New Load box when Building mass and Area load are selected, to make users aware of this possibility.
If no wall was selected and Selected wall was chosen in the Apply to... combo box when adding a new load, a large value automatically appeared in the From X= and To X= fields. Furthermore, you are allowed to enter a load which appeared on a random building face.
The program has been changed to revert to the previous Apply to... selection in this case.
For wind uplift loads, in the Application input of the Add a New Load dialog box, you can now add the loads to selected walls. Previously only the full wall line was available.
