Sizer 9.01 Hot fix

Jan 21, 2011 – Hot fix

Version 9.01 released as a “hot fix”, a self-extracting file available from the WoodWorks website to be expanded into the Sizer 9.0 installation. The first Design Office edition that included these changes was Design Office 9, Service Release 1, released July 29, 2011.

All of the following problems were introduced in version 9 of the software.

1. Non-dead Loads Duplicated as Live Load In Concept Mode (Bug 2232)

   When a non-dead , non-live load (snow, wind, roof live, earthquake, or impact) was added to a member in concept mode that did not also have a live load, the loads created from reactions on the members below included an extra live load of the same magnitude as the other non-dead load. This load was used for design of the supporting member, leading to overly conservative sizing, and is also distributed to members further down the structure.

   In a typical case, roofs loaded with only snow and dead loads are supported by members that are given an extra live load with the same magnitude as the snow reaction, in addition to the snow reaction load. This extra load could be eliminated by placing a live load with negligible magnitude on the roof.

   The problem only occurred when the original supported member is designed for dry service conditions.

2. Critical Member in Design Groups for Multi-ply Members (Bug 2242)

   The program did not properly take the number of plies into account when determining the member of a design group with the largest cross-sectional area, leading it to misidentify the critical member in a design group in Concept Mode.

3. Crash on Design of New I-joist Project (Bug 2223)

   When designing a new floor joist or roof joist project with I-joist as the material, a crash would result. If this happened after saving, the project was saved and could be opened and designed without a crash occurring.

4. Crash in Concept Mode for 6-Span Beam with Left-end Cantilever (Bug 2231)

   In Concept mode, Sizer crashed when trying to design a 6-span beam with a left-end cantilever.

5. Crash for Left Cantilever Beams with Specified Lateral Support (Bug 2246)

   Sizer hangs and freezes the computer when accessing Loads view for beams and joists with left cantilever and lateral support other than "At supports" or "Full" ( a numeric value) , for operating systems other than Windows 7.

6. Deletion of Spans in Cantilevered Beams (Bug 2226)

   Trying to delete any cantilevered span or the non-cantilever span on a 2-span cantilevered beam, causes the program to crash.

   Deleting the middle non-cantilevered span on a 3-span, doubly cantilevered beam creates a corrupted beam that cannot be designed.
