BREVe3
BREVe3 automates the design wind speed and dynamic pressure clauses of BS6399-3 and EN1991-1-4 for any site on the UK National Grid.
ActiveX technology allows you to embed the power of BREVe3 into any compatible application, including Excel spreadsheets.
What BREVe3 does
BREVe3 automates the design wind speed methods in:
- British Standard BS6399-2:1997 Loading for buildings. Code of practice for wind loads, 1997, and
- EN1991-1-4 Eurocode 1: Actions on structures - Part 1-4: General actions - Wind actions (UK National Annex).
- For any site in the UK (excluding Northern Ireland).
BREVe3 reports: - Design wind speed and dynamic pressure from both the standard and directional methods of BS6399-2, the hybrid method of BRE Digest 436, as recommended by DETR.
- The UK National Annex methods of EN1991-1-4 for mean wind speed, turbulence and gust speeds.
- The full method of the BRE Designer's guide to wind loading of building structures, from which the BS and EN methods were derived, using BS or EN base wind speeds.
- BREVe3 reports gust speeds for use in static design and mean wind speed and turbulence intensity for use in dynamic design.
- The BREVe3 Application gives the user full site control and reporting of all BS6399-2:1997, EN1991-1-4 and Designer's guide methods in a stand-alone program.
- Alternatively, the user may integrate all the BREVe3 functions directly into other applications, including Microsoft Word documents or Excel spreadsheets, using the BREVe3 ActiveX component.
- The BREVe3 Application and ActiveX control will list all the intermediate parameters used in obtaining the result.

How BREVe3 does it
From just the National Grid reference, BREVe3 determines the site parameters automatically from extensive databases of ground roughness and altitude anywhere on the UK National Grid.
The topography analysis now determines the full BS/EN topography parameters for each sector from a new high-resolution altitude database. The user may adjust the radius of the site to see the effect at the most exposed position on the site.
The Automatic Wizard adjusts the site exposure and topography to give the optimum safe results within each 1km grid square without any need for the user to enter data. Alternatively, the Manual Wizard offers a series of standard choices to obtain only such additional information as is needed about the site to refine the site location to 100m resolution. The safe choice used by the Automatic Wizard is always pre-selected.
The Site Editor allows all the site parameters to be adjusted individually and parameters for sites outside the UK to be entered by hand.
Key improvements from Versions 1 and 2
BREVe3 still uses the BRE database of roughness categories from the Designer's guide, but the rules for significant roughness changes have been upgraded to comply with BRE Digest 436.
Topography analysis is now completely automatic by virtue of a new high-resolution Ordnance Survey database that allows BREVe3 to define the full topography parameters for each direction. The parameters refer to the most exposed position user within the radius of the site, adjustable by the user. There is now no need to refine the topography analysis using the Site Editor unless the topographic feature is smaller than the database resolution (200m).
Reporting to the Eurocode EN1991-1-4 has been added.
The "engine" of BREVe3 is now incorporated into a Dynamic Link Library (DLL) as well as an ActiveX component (OCX). This BREVe3 can now be integrated into any compatible software, including spreadsheets such as Excel, allowing the user to customize applications.
