AS / NZS 1170 雪荷载计算

在AS / NZS中使用SkyCiv Load Generator 1170.3 雪荷载计算

使用SkyCiv Load Generator计算结构的雪荷载压力, 该过程是首先定义代码参考. 从那里, 工作流程是在“项目”选项卡中定义参数, 网站标签, 和建筑标签, 分别. 然而, 只有具有专业帐户的用户或购买了独立Load Generator模块的用户才可以使用此计算. 您可以通过此购买独立模块 链接.

网站数据

Using the AS/NZS 1170 snow load calculation, you need to define the Annual Recurrence Interval or the SLS/ULS parameters. After selecting the options for these parameters, you need to put the address of the structure. The corresponding snow load for the address will be automatically calculated. Take note that this value is based on the following:

  • 部分 2 AS / NZS的 1170.3 for classification of snow regions based on Figures 2.1 和 2.2 and based on elevation
  • 桌子 5.2 for specific locations in Australia

Take note that the snow region classification automatically displayed in the module shall prioritize the classification of the area based on elevation. To display the snow region map based on Figures 2,1 和 2.2, you need to clickView Map Contoursand then select “雪” – “Australia/New Zealand.For Australian locations indicated in Table 5.2, the user should selectTerrain Classification for Snowas given in AS/NZS 1170.3 Supp 1.

Snow Exposure Category

This parameter is used in getting Exposure Reduction Coefficient CË. The definition of each option is defined in table below:

暴露类别定义
Sub-alpineSites classified as sub-alpine region.
庇护所Sites where roof is protected from the wind by obstructions such as other structures, terrain features or numbers of closely spaced trees higher than the roof.
SemishelteredSites where roof is only partially protected by numbers of scattered obstructions higher than the roof (例如, scattered trees).
WindsweptSites where the roof is exposed on all sides, with no protection provided by obstructions, trees, or terrain features higher than the roof.

考虑不平衡/降雪量的情况?

This parameter is a “Yes” or “No” to calculate for Unbalanced Snow Load Case. Upon selecting “No,” the balanced snow load case shall only be calculated. 另一方面, upon selecting “Yes,” the unbalanced snow load case table will show. There are four options for AS/NZS 1170.3 alpine region:

Drift on duopitch roof

This case is used to calculate the drifted snow load on duopitch/gable roof as shown below:

数字 3. Parameters for calculating drifted snow load on duopitch/gable roof.

Drift on monopitch roof

This case is used to calculate the drifted snow load on monopitch/monoslope roof as shown below:

数字 4. Parameters for calculating drifted snow load on monopitch/monoslope roof.

Drift on lower roof

This case is used to calculate the snow load drift on lower roof level.

数字 5. Parameters for calculating drifted snow load on lower roof.

Drift on projections and obstruction

This case is used to calculate the snow load drift on obstructions above the roof level such as parapet walls, firewalls, 烟囱, 等等.

数字 6. Parameters for calculating drifted snow load on obstructions and projections above roof.

另一方面, there are additional two options for AS/NZS 1170.3 sub-alpine region:

Drift on obstructed roof with parapet

This case is used to calculate the snow load drift on parapet walls in sub-alpine region.

数字 7. Parameters for calculating drifted snow load on obstructed roof with parapet in sub-alpine region.

Drift on obstructed roof with abutting

This case is used to calculate the snow load drift on obstructed roof with abutting in sub-alpine region.

数字 8. Parameters for calculating drifted snow load on obstructed roof with abutting in sub-alpine region.

结果

The snow load results will show the parameters in calculating the undrifted snow load for either alpine or sub-alpine region as shown below:

数字 9. Snow load parameters used in calculation and the calculated undrifted snow load

Drifted/Unbalanced Snow Load

如果考虑选择不平衡/降雪量, 结果根据定义的情况列在表中:

数字 10. Sample results for unbalanced/drifted snow load on duopitch and monopitch roof, 分别.
数字 10. Sample results for unbalanced/drifted snow load on lower roof and on projections and obstructions, 分别.
