Table Headings, Legends and Notes
Design Case in Heading
At the top of each table, and at the top of each page of results for each table, the design case is now given in brackets, e.g. (rigid wind design). Previously this just appeared at the top of new pages in the Shear Results table.
Separate Lines
The following legends have been broken into separate lines for each item for enhanced readability:
Additional Information
The following legends have been improved:
Among the more common improvements are
Legend-Note Separation
A blank line has been inserted between the legend and the notes for all tables, for better readability.
Failure Messages (Change 70)
Any warning message indicating design failure in any way is now in red type. For example nail withdrawal design warnings
Hold-down and Drag Dtrut Calculation Procedure (Change 83)
The program now indicates in the legend whether the hold-down and drag strut design force shown is based on applied shear force or shearwall capacity. A setting in the Design Settings controls this.
Design Settings table
Hold-down and Drag Strut Force Calculation Method
Two lines have been added
Drag strut forces based on
Hold-down strut forces based on
These then show Applied forces or Shear capacity.
The setting had been in the program, but not echoed in the output.
Design Shear Wall Force/Length
A cell labelled Design Shear Wall Force/Length has been added to reflect values in the cell come from the new design setting, Design shear force based on wall rigidity.
Height-to-width Ratio (Change 104)
Despite the fact that the user has no control over this, we still show this value, which is now always 3.5, and added the unblocked height-to-width ratio limit of 2.0
Disregard Height to Width Ratios (Change 104)
This setting is manifested by dashes appearing in the Height-to-width ratio field.
Site Information
Calculated Period (Bug 2279)
In the Site Information section of the Design Results, the calculated period shown was the one entered in the Site Dialog, rather than the period calculated in 4.1.8.11. The entered period is also shown, so these two lines were always the same.
Percentage Storey Shear Resisted By Gypsum Wallboard Table (Change 80)
In this table, some of the lines dividing the columns have been removed to make the table have a more consistent format with other tables.
Components and Cladding Table
No Capacity Message (Change 73)
When a material such as gypsum wallboard that has no sheathing C&C capacity was used on an exterior surface, the program was outputting a warning note saying it failed the withdrawal capacity check, and another saying that the material on the exterior has no shear capacity. Only the second note, about no shear capacity, is output now.
Irregularities Table and Screen Messages
Notes for Drag Strut and Hold-down Capacity Provisions (Bug 2021)
The correction made for version 7.2, listed below, was reverted to the previous behaviour for subsequent versions, 7.21 and 7.22. This correction has been restored.
Reference to Capacity of Elements Supporting Discontinuous Walls (Change 85)
A reference to clause 4.1.8.15-4 was showing up instead as ???. This was in a warning message saying that drag struts and hold-downs on floors below a discontinuity must be designed for the capacity of the upper floor.
Irregularity Check Warning Message Box (Change 86)
The message box that appears on the screen when the design fails due to Irregularity 4 for in-plane stiffness or Irregularity 6 for a weak storey, from NBC 4.1.8.6, appeared when the irregularities existed in the walls designed for flexible diaphragm analysis only. If these irregularities existed for rigid diaphragm analysis, but not flexible, the box for Irregularity 6 did not appear, and the box for Irregularities 3,4 and 5 either didn’t appear or didn’t mention Irregularity 4 for stiffness. The boxes now appear for rigid analysis when they should.
