4.2 Gamma Bracing Software - Achieved
CALCULATING THE ACHIEVED
The bracing calculation sheets listed below are available within the Gamma
Bracing software to calculate the bracing achieved requirements for house
types that are accordance with the NZS3604:2011 standard. Depending on
the type of house refer to Table 2 when choosing the achieved sheets
Subfloor Along Sheet
Subfloor Across Sheet
Lower Along Sheet
Lower Across Sheet
Upper Along Sheet
Upper Across Sheet
Each achieved sheet allows the option to choose from the preferred
Gamma Bracing systems individual bracing elements as well as the bracing
systems listed below. These systems will require the correct references and
values to be inputted prior to being used in each of the achieved sheets.
PRINT SHEET
The Print Sheet automatically stores data from the Main Menu and each of the Along and Across sheets to provide a print version of the bracing
calculations. Once the calculations have been completed go to the Print Sheet to print off the information.
Strictly follow the manufacturer’s instructions and ensure the correct
Wind and Earthquake values are used. When panel or sheet bracing
systems are used the wall length will be required to calculate the
bracing values of each bracing element.
Foundations
Plywood
Plasterboard
User Defined (Customer bracing systems)
The wind and earthquake demand values from the demand sheet are
displayed cells at the top of the achieved sheet. Calculate the bracing
achieved until the demand value is achieved or exceeded.
For exterior wall bracing lines load in the exterior wall length in
meters and ensure the demand value detailed for that bracing line is
achieved.
A warning note will be visible if the demand is not achieved.
