Important Note – These are descriptions to changes implemented in WoodWorks Shearwalls for version 11 and may not reflect current program behavior.
Numerous improvements have been made to the Elevation View drawing. Refer to the B:Engineering Design section for physical explanations and design code references pertaining to the information presented.
You are now able to zoom Elevation View in and out and to establish view settings similarly to Plan View.
A tab for Elevation View has been added to the Settings box, with similar inputs to the View tab for Plan view. The setting previously called View has been changed to Plan View.
You can establish the confines of your viewing area with the View area inputs, or change them using the Zoom buttons in the Elevation View data bar.
These settings act similarly to Plan View, allowing you to recapture the full image of the structure after it has been zoomed.
Since there is no interactive input in Elevation View, the snap increment entered in the Plan View settings is shown here, and is used as the metric for the Display gridlines input.
You can now display gridlines at a different interval from how they are shown in Plan view using this input.
You can set the percentage by which the image expands or contracts each time the Zoom in and Zoom out buttons in the Elevation View data bar are pressed.
Zoom in and Zoom out buttons in the Elevation View data bar expand or contract the image by a percentage increment entered in the Elevation View settings.
It is also possible to zoom the image via the mouse wheel, owing to the new feature described in .
In the Show menu and in the Display data group of the Options settings, you can now turn on and off the display of segment numbers, and aspect ratio information, separately.
In the upper portion of shearwall segment, centered horizontally, the program shows the segment number after the wall number, e.g. A-1,1; A-1, 2; etc.
Under the segment number is the aspect ratio of the segment, shown as A.R. followed by the value.
For those segments that have an Aspect Ratio factor or adjustment other than 1.0 (i.e. segments with aspect ratios greater than 2.0 for wood panels and 1.0 for fiberboard), under the aspect ratio it shows the factor or adjustment. For deflection-based force distribution the factor is preceded by Fact; for capacity-based distribution it is preceded by Adj.
Within the design results text below the drawing, the program now gives the critical segment, e.g. A-4,2, in which 4 is the wall number and 2 is the segment number. Previously it just indicated the segment was within wall A-4.
For perforated shearwalls, segment numbers are not shown, because they do not correspond to segments shown in the Design Results output and they are not used independently in force analysis or design.
The aspect ratio for perforated wall segments is shown as it is for segmented walls, as it is used to factor the shearwall length used in calculating the Co factor.
For all segments, including non-FHS segments, the segment length Li, possibly factored by aspect ratio factors adjustments, is shown, in feet.
For non-FHS segments, the value of Li is 0.00.
The sum of factored segment lengths ∑Li and the total wall length Ltot used in the calculation of the perforated wall factor in SDPWS Eqn. 4.3-5 now appear after the perforated wall factor Co under each perforated wall.
The word "Perforated" has been removed as it is now evident from all the data specific to perforated walls.
Dimension lines indicating the length of full-height segments or of perforated walls, opening length and height, joist depth and wall height are now shown in Elevation View.
In both the Show menu for Elevation View, and in the Display data group of the Options settings there is a checkbox to turn off the display of dimensions for walls and for openings independently. Joist thickness is also turned off when walls are turned off.
Full height segments in all segmented shearwalls and entire perforated walls or non-shearwalls are dimensioned in the bottom area of the wall.
The horizontal dimension of openings is shown on top of the opening if there is room, otherwise within the opening.
The vertical dimension of openings is shown inside the opening on the right-hand side.
The wall height is dimensioned to the left of the entire shearline, and the joist thickness to the right.
Dimensions are in feet, and you can control whether feet-inch or fractional feet, and whether fractional inches are shown, using the Imperial Format setting for Distance.
The following elements are now shaded in light gray to indicate that they are not considered shear resisting elements.
Within segmented walls, segments which are too narrow to be considered full-height segments, and are this not included in design and do not draw force, are shaded.
Openings are shaded above and below the opening
For perforated walls, only non-full-height segments at the ends of the walls before any full-height segment is encountered are shaded.
Non-full-height segments that have full height segments both before and after them anywhere in the wall are not be shaded because the length Ltot includes such segments.
Non-shearwalls are shaded except for the openings.
In the Show menu while in Elevation view and the Display data group of the Options Settings in the Elevation view column, items have been added for the display Gable end and for Roof.
When Roof is checked, the Gable end is always shown and its checkbox is disabled and checked.
This setting controls the display of the triangular gable end of the wall. If the setting Ceiling acts as upper level diaphragm is checked in Structure view, this portion of the wall is not considered part of the shearwall, and turning off the setting economises on space without compromising the depiction of forces on the line.
This setting controls the display of side panels and hip ends, which do not affect the distribution of forces within the shearline, so this setting can be turned off to economize on space if only the forces within shearwalls are of interest
Gable ends are part of the end wall, and it was previously unclear whether they were considered part of the shearwall, as they are if Ceiling acts as upper level diaphragm is unchecked in Structure view,
If selected for display, gable ends are drawn in the same green colour as the wall.
When Ceiling acts as upper level diaphragm is unchecked in Structure view the program draws the arrows for the diaphragm shear force and the segment shear forces along the slope of the gable end rather than at the level of the top of the upper storey.
These force locations are used in the calculation of the moment arm for hold-down force calculations, however previously that was not apparent.
If you choose not to draw gable ends, then the forces are drawn along the top of the upper level wall at eave height, even though they act at the height of the sloping roof.
Hip roof panels and side panels are drawn in a mid-gray colour, and the entire outline of the panel is drawn, including the line at eave height.
The panels are drawn only if the roof block edge is collinear with the wall, in other words, if the roof is made of rafters, the wall supports the rafters.
Roof panels are drawn only for those blocks whose highest level corresponds to one of the levels selected in Elevation view.
You can now choose to view Selected Walls while viewing multiple levels or multiple levels while in Selected Walls mode. In this case, the program shows only walls that are above and below the selected walls. This allows you to view see the entire vertical load path for a single stack of walls. Previously, it was difficult to do so for long shearlines because the data tended to overlap.
Previously, when Selected Walls was chosen in Elevation view, the levels control was disabled. Now it is enabled.
When in Selected Walls mode while more than one level is being viewed, the program uses the walls on the level selected in Plan view to determine what walls are shown on other levels. It shows all walls on other levels that are entirely within the extents of the selected walls.
If contiguous selected walls are selected, the program shows walls on other levels within the total extent of the contiguous walls, even if they do not lie within the extent of any one of the selected walls. However, if there is a gap between selected walls, the program does not show walls on other levels that lie even partially within that gap.
If you find this difficult to envision, just experiment with the program.
The total shearline force that usually appears at the top of the first wall on the line in Elevation view did not appear if it was less than the shearline force for the opposite direction from that which is being shown. This has been corrected.
In the Elevation View drawing of the Anchorage Shear force t for perforated walls from SDPWS 4.3.6.4.2.1, the arrows are now drawn so they do not obscure the shear force and anchorage force values, and the anchorage force has been raised so that it does not overlap the shear force.
For multi-storey structures, the numeric value of the shear force on each segment has been raised above the arrows for the design shear force on the storey above, if they would otherwise be obscured by them or by the diaphragm itself.
For shearwalls offset from the shearline location, and if dead loads were on the wall, the program was crashing when Elevation View was viewed. This ha been corrected.
When individual walls from different shearlines were selected in Plan view, Elevation view in the Selected Wall mode showed all these walls, even if they overlap. Now the program shows only the walls from the first shearline selected, as it does when multiple entire shearlines are selected when in Entire Shearline mode.
After re-entering the Structure action or Roof action in Plan View are selected, then going to Elevation View, the Level input was disabled and you were unable to change the levels being viewed. This has been corrected.
When walls on a shearline are offset in plan from neighboring walls, in Elevation view the offset walls were drawn slightly than normal, causing a small gap between walls. This occurred consistently when viewing one level and occasionally when viewing multiple levels, and has been corrected.
After disabling the framing, nailing, or sheathing information under the shearwalls in Elevation view, it did not rescale to accommodate the change in information. This resulted in you being unable to see the information when it was re-enabled, or the view having a large amount of blank space along the bottom when the information was disabled. These problems have been corrected.
Occasionally, when the segment aspect ratio was between 2 and 3.5 so that an aspect ratio factor is applied, no design force was shown in elevation view for that segment. The aspect ratio factor was applied to the design shearwall force as shown in the Shear Results table, so this was a graphical display problem only. It has been corrected.
After running a design, it was not possible to turn off all hold-down forces via the Show menu, just to choose between combined and separate hold-downs. This has been corrected.
Added a separator to the Elevation View Show menu separating the options dealing with graphical elements such as wall names with those dealing with design results text.
