在 1991 雪荷载计算

在 EN 中使用 SkyCiv Load Generator 1991-1-3 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

使用英文 1991-1-3, 您需要先在“项目地址”输入中输入一个地址,然后软件会自动获取该位置的积雪量. 目前, 负载生成器支持以下国家:

  • 比利时
  • 法国
  • 德国
  • 爱尔兰
  • 卢森堡
  • 荷兰人
  • 英国

The snow load values were obtained using Appendix C of EN 1991-1-3 或每个国家附件. To display the snow region map, you need to clickView Map Contoursand then selectSnow.

结构数据

结构数据和风雪参数被分为不同的手风琴. 为了计算雪荷载, 应选中“雪荷载”复选框.

Topography for EN 1991-1-3 Snow Calculation

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

Topography定义
WindsweptFlat unobstructed areas exposed on all sides without, or little shelter afforded by terrain, higher construction works or trees.
普通的Areas where there is no significant removal of snow by wind on construction work, because of terrain, other construction works or trees.
庇护所Areas in which the construction work being considered is considerably lower than the surrounding terrain or surrounded by high trees and/or surrounded by higher construction works.

Type of Snow

This parameter is used in getting the mean bulk weight density of snow, C. The definition of each option is defined in table below:

Type of SnowBulk weight density kN/m3
Fresh1.0
Settled (several hours or days after its fall)2.0
老的 (several weeks or months after its fall)3.0
Wet4.0

设计状况

目前, Design Situtation is limited to Normal Condition.

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.

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

Drift on roof abutting to taller construction works

This case is used to calculate the snow load drift on roof abutting to taller construction works.

数字 6. Parameters for calculating drifted snow load on roof abutting to taller construction works.

结果

The snow load results will show the parameters in calculating the undrifted snow load as shown below:

数字 7. Snow load parameters used in calculation and the calculated undrifted snow load

Unbalanced/Drifted 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 8. Sample results for drifted snow load on duopitch and monopitch roof.
数字 9. Sample results for drifted snow load on projections and obstructions, and abutting to taller construction works.
