Premium Software Revolutio CHECKWIND v.8.4.2 (Site-Specific Wind Analysis) Download 2026-01-21

Summary​

CHECKWIND is a professional wind analysis and Structural Software developed by Revolutio that provides site-specific wind load calculations for engineering design projects. It is widely used by structural engineers, designers, and construction professionals to determine wind pressures, terrain effects, and directional factors at precise locations anywhere in the world.
By integrating mapping tools such as Google Maps and automated hazard databases, CHECKWIND enables users to generate accurate wind load parameters that conform to global design codes and standards.

Purpose and Engineering Context​

The primary purpose of CHECKWIND is to automate the calculation of wind load parameters for specific sites and to support design compliance with international codes. Wind analysis is an important part of structural design, affecting how buildings, poles, towers, and other structures must be engineered to withstand climatic forces. CHECKWIND eliminates the need for manual lookup of wind speeds or rough terrain factors by fetching and calculating these values quickly based on location, topography, and code requirements. With its automated tools, engineers save significant time and reduce the risk of error during design preparation.

Integration With Design Standards and Codes​

It supports a broad range of internationally recognized wind design standards, ensuring its calculations are valid across different regions and jurisdictions. These include Australian standards like AS 4055 and AS/NZS 1170.2, American standards such as ASCE 7-10/16/22, Canadian code CSA S37-18, European standards EN 1991 and EN 40, Indian standards IS 875, and others such as TIA-222-H/I for telecommunications structures. These comprehensive standards support help engineers apply code-consistent wind pressures whether they are designing for local, regional, or global projects.

Automated Site-Specific Wind Calculations​

One of the defining features of CHECKWIND is its automatic wind load generation based on precise site information. Users can enter an address or geographic coordinate, and the software uses mapping data and terrain classification logic to calculate wind region, exposure categories, shielding factors, and topographic multipliers, all of which influence how wind forces act on a structure. These calculations are essential for creating safe and compliant designs because wind loads vary significantly with terrain features and directionality.

Use of External Data Sources and Mapping Tools​

Its advanced analysis engine uses external data sources, including Google Maps and other geographic services, to determine terrain categories, shielding effects, and directional topography. Additionally, for codes such as ASCE 7, the software retrieves basic wind speed values directly from the ASCE Hazard Tool, ensuring that the most current hazard data feeds into site calculations. This integration reduces the burden of manual data entry and improves the accuracy of the wind load predictions used in structural design.

Terrain and Shielding Classification​

Accurately classifying terrain and shielding conditions is critical for precise wind analysis because the roughness of the surrounding landscape and nearby structures significantly influences wind pressures. It uses machine learning and mapping techniques to detect terrain categories, directional shielding classes, and topographic features, then applies these factors to design wind calculation methods. By automating these classifications, the software prevents common manual errors and boosts confidence in the resulting load values that will be used in structural design models.

Directional Analysis and Wind Multipliers​

Wind loads are not uniform in all directions, and structures must be assessed for the effects of wind coming from multiple orientations. It calculates directional multipliers such as velocity pressure coefficients, terrain multipliers, topographic factors, and shielding multipliers for different compass directions, which help refine the design wind pressures for any given site. Such directional assessments are vital for structures like tall buildings, transmission towers, and sign supports where wind effects vary widely based on orientation.

Comprehensive Site Reports and Documentation​

After performing wind load calculations, it produces detailed site reports and wind parameter summaries that can be exported and integrated into project documentation. These reports include wind speeds, terrain data, directional pressure coefficients, satellite image overlays, and other key details that engineers require for structural analysis reports, compliance verification, and client deliverables. Professional reporting helps ensure that designs are well documented and defensible during reviews or regulatory submissions.
