Wind, Snow, and Seismic Load Software

Use the SkyCiv Load Generator to quickly and easily generate wind, snow, and seismic loads based on a variety of codes for your project's design criteria. Take advantage of the easy user interface to get through the calculation effectively, then print out the site reports or design load reports to a PDF for later use as a deliverable. Directly apply the design loads from the Load Generator onto your project's 3D model in Structural 3D.

SkyCiv Wind Speed Maps

Get design wind speeds

  • Simply enter the location, zip code, or latitude/longitude of your project
  • Simple options for importance levels, risk categories, and more
  • Click and drag the pin to calculate wind speeds quickly
  • Auto calculation of Terrain Data, including topography factors
  • Clear elevation profile graphics to show site terrain factors

Currently Supports: ASCE 7-10, ASCE 7-16, ASCE 7-22, AS/NZS 1170, NBCC 2015, NBCC 2020, EN 1991-1-4, IS 875-3, NSCP 2015, CTE DB SE-AE, and CFE

Calculate wind design pressures

Once the wind speed has been calculated (or manually entered by the user) you can then proceed to enter building information such as the type of structure and relevant structure parameters to calculate the wind pressures on your structure.

  • Full calculation of design pressures and elevations on walls and roof
  • Windward, Leeward, Sidewall, and roof pressures
  • Calculation of pressure for roof and wall components and cladding
  • Topographic, Directional, Gust, Exposure coefficients
  • Clean and professional PDF reporting, with detailed results

Currently Supports: ASCE 7, AS/NZS 1170, NBCC, EN 1991, IS 875, NSCP, CTE DB SE-AE, and CFE requirements.
Structure Types*: Buildings (open and closed), signs and billboards, free-standing walls, etc

SkyCiv Load Generator Snow Loads

Automatic snow loads

The SkyCiv load generator will also calculate the design snow loads and snow pressures required to be applied to your model, including:

  • Generate snow loads for your structure - from simple roof case to roof with projections and multilevel roofs
  • Snow load cases for gable, mono slope, and multilevel roofs
  • Simplified and intuitive snow load result figures
  • View snow load contours on the map viewer
  • Add multiple load cases for easier calculation
  • Clean and professional PDF reporting, with detailed results

Currently Supports: ASCE 7-16, NBCC, Eurocode, and Australian Standards

Apply directly to your model

The SkyCiv Wind Load module is completely integrated with SkyCiv 3D structural analysis software , so you can instantly apply your design pressures to your structure. The structural design software will auto calculate the tributary widths and apply DLs quickly and easily. Generate and check your wind load in a few clicks!

  • Simple node entries to apply the wind pressures
  • Dynamic Loading - as the structure changes, the wind loads adjust themselves
  • Auto apply load combinations and factors
  • Auto calculates tributary widths and applies DLs to internal members
  • Edit, Remove, or Adjust wind loads at any time

SkyCiv Load Generator API Sandbox

API access

The SkyCiv Wind, Snow, and Seismic Load API Supports direct access to this technology with a simple HTTP request. This means you can get your wind speeds, pressures, snow pressures, seismic loads, and more with a direct API call, including:

  • Use API to get the wind speeds and snow loads of the structure based on the address
  • Use API to generate the wind and snow pressures
  • Use API to calculate the seismic loads (ASCE 7-16)
  • Returns full summary and detailed PDF reporting
  • Perfect for design automation

Detailed design reporting

The SkyCiv Load Generator module includes clean and powerful reporting, with different levels of detail - depending on your needs.

Wind speeds and loads are accompanied with map information, step-by-step calculations of the elevation and design factors (such as topography, directional, gust, exposure coefficients) as well as the final design pressures and results. Perfect to include with your project documentation.

Snow design pressures also include step-by-step factors such as exposure, thermal, importance and many more, depending on your design code of choice. The final snow load is also provided for clear and concise reporting.

Seismic load calculation report that shows the assumptions and parameters, giving you confidence in the results that you will be using in your design.

SkyCiv Load Generator Structure Types

Multiple structure types

Aside from buildings, the SkyCiv Load Generator supports several structure types for wind and/or snow load calculations. These are:

  • Buildings
  • Freestanding wall (ASCE 7)
  • Signboards (ASCE 7 and EN 1991)
  • Poles (EN 1991)
  • Solar Panels (ASCE 7 and AS/NZS 1170)
  • Truss Tower (ASCE 7)
  • Rooftop Equipment/Structures (ASCE 7)
  • Open Frames/Signs (ASCE 7)

Generate seismic loads

The SkyCiv Load Generator module now includes seismic load calculations for ASCE 7-16, NZS 1170.5, NBCC 2020, and NSCP 2015. Determine the seismic base shear and diaphragm forces that you can apply to your structure based on site seismic parameters from USGS. Generate the design response spectrum that can be applied to your S3D model! Get the detailed seismic report with just a few clicks so you can be confident with your output.
