calculating wind loads in accordance with the revised UK
National Annex to Eurocode 1 is now available to roofing and
cladding manufacturers and contractors through Roofconsult,
the independent roofing and cladding consultancy. |
 |
|
Roofconsult’s Roofwind range of spreadsheets has been
updated to meet the UK National Annex to Eurocode 1 -
Actions on structures Part 1-4: General actions - Wind
actions (BS EN 1991-1-4:2005), which was revised earlier
this year. To download

The Roofwind range of Excel
spreadsheets comprises the original wind loads calculations
to BS6399 launched by Roofconsult on its formation in 2003 –
Roofwind – and its bigger brother RoofwindPlus, as well as
the new European code spreadsheets. |
|
RoofwindEN calculates wind loads
based on two categories of terrain - town or country - and
where the orography (topography) is not significant. Data
has to be manually fed in. But RoofwindPlusEN uses site data
from the
Fastrak BREVe programme from CSC (UK). |
|
From just the National Grid
reference of the site, Fastrak BREVe determines the site
parameters automatically from extensive databases of ground
roughness and altitude for sites in the UK and Ireland, and
calculates site exposure to give optimum results. |
|
Considerations include building
measurements, dominant openings, roof pitch, adjacent
buildings, site altitude, distance to sea and town, and
probability (1 in 50 years storm) factor. |
|
David Roy FIoR, managing
director of Roofconsult, which specialises in flat roofing
and metal sheeting and cladding, said: “All public funded
buildings should have been designed in accordance with the
Eurocode from April 2010. |
|
“With the publication of the
revised national annex in January, now is a good time to
update the spreadsheets to the current British Standard.” |
|
The Roofwind spreadsheets can be
customised for individual products or systems, such as
single ply membranes, composite panel fixings and roof-based
photovoltaic systems, and are priced from £350. |
