GCALCULATION OF LOADS ACTING ON ROOF

Calculation of loads acting on a roof should be conducted according to the relevant up-to-date stan-dards. In case of flat roofs, loads from wind and snow in particular need to be examined closely. (Although for thermal insulation roofing fixings any loads from snow action do not have a direct influence.) For pro-per selection of these fixings precise evaluation of wind suction loads acting on individual elements of the roof is necessary. For such purposes, information included in EN 1991-1-4 “Actions on structures – Part 1-4: General actions – Wind actions”, as well as in national annexes, are obligatory.

The national annexes of EN 1991-1-4 contain data on wind loading zones for specific countries. This information should be applied to calculations.

The major values and factors determining loads are as follows:

THERMAL AND HYDRO INSULATION FIXINGS FOR FLAT ROOFS

RAWLPLUG/KOELNER fixing systems are the most economical method for ensuring a long roofing lifes-pan with maximum reliability and security.

Roofing surfaces, especially in flat roofs, are subject to constant wind suction and shear forces, caused by the normal operation of roof elements.

Various potentially destructive influences can affect roofing, including: a) wind – so called ‘wind roll’ (suction and shear load)

b) sun – alternate heating and cooling of roofing materials (causing tensile load)c) precipitation – influence of water and snow deposits (compressive and shear load)Consequently, it is important to utilise verified, safe fixings for thermal and hydro insulation layers.RAWLPLUG/KOELNER benefit from extensive experience in ensuring safe fixing of thermal and hydro

insulation in many projects domestically and abroad. High product quality is confirmed and supported by technical approvals and certificates, permitting RAWLPLUG/KOELNER products to be used in civil engi-neering and roofing systems in which the following parameters were tested: – static values, obtained from pull out testing – anticorrosion protection in Kesternich cycles according to DIN 500 18 KFW 2.0 S – batch identification through marking on product and packaging

The guarantee provided by Allianz insurance company for all RAWLPLUG/KOELNER roofing insulation fixings acts as an indication of the confidence and trust in the products produced by our company, as well as their suitability for use in professional and responsible activity.

Proper installation of our roofing insulation fixings will provide a foundation for safe and durable func-tioning of the overall roofing system.

Realisation of a successful application can be ensured by the following actions:a) calculation of the optimum fixings quantityA deficit of fixings can be dangerous due to wind suction forces as well as the additional work demands

on roofing in changeable weather conditions. Conversely, a surplus may cause excessive perforation and, in the case of POK and POW aluminium washer solutions, extensive thermal bridging. The optimum quantity of fixings should be calculated according to wind standard EN 1991-1-4:2005 (Eurocode 1). When the calculation is not possible, the quantity can – after consultation with our technical department – be assumed, according to wind standard DIN 1055, as being:

– in corner areas – 9 pcs/m2

– in edge areas – 6 pcs/m2

– in middle area – 3 pcs/m2

b) seeking recommendations for selection of installation equipment:Please always contact our technical advisors regarding: – screwdriver coupling settings– selection of appropriate installation bits

– training in the use of appropriate installation tools by one of our technical advisors, who will pay you a visit

vb = cdir . cseason . vb,0 [m/s]

The basic wind velocity:

where: Vb – basic wind velocity, defined as a function of wind direction and time of year, at 10 m above

ground of terrain category II, Vb,0 – fundamental value of the basic wind velocity (i.e. the 10 minute mean wind velocity, irrespec-

tive of wind direction and time of year, at 10 m above ground level in open country terrain with low vegetation such as grass and isolated obstacles with separation of at least 20 obstacle heights),

cdir – the directional factor (the value for various wind directions may be found in the National Annex – the recommended value is 1.0),

cseason – the season factor (the value may be given in the National Annex – the recommended value is 1.0).For permanent buildings the standard recommends to assume a value of 1 for the directional and

season factors.

The mean wind velocity at height ‘z’ above the terrain depends on the terrain roughness and orogra-phy and on the basic wind velocity. It is determined as

vm(z) = cr(z) . co(z) . vb [m/s]

Vb– the basic wind velocity [m/s], z – height above the terrain [m],

cr (z) – the roughness factor, co – the orography factor.

The roughness factor cr (z) depends on the height of the structure and terrain roughness upwind

cr(z) = kr . ln z0 for zmin ≤ z ≤zmax

cr(z) = cr(zmin) for z ≤zmin

z0 – the roughness length (Table 1),zmin – the minimum height (Table 1),zmax = 200 m,

kr – terrain factor: kr = 0.19 . zz

z0,II = 0.05 m,z0 – the roughness length (Table 1).

1 according to EN 1991-1-4, table 4.1

The terrain roughness to be used for a given wind direction depends on the ground roughness and the distance with uniform terrain roughness in an angular sector around the wind direction. The National Annex may give definitions of the angular sector and of the upstream distance. The recommended value of the angular sector may be taken as the 30° angular sector within ±15° from the wind direction.

When there is a choice between two or more terrain categories in the definition of a given area, then the area with the lowest roughness length should be used.

The orography factor co is taken as 1.0 – however, information about the factor may be given in the National Annex or it may be calculated according to Annex A.3.

EN-1991-1-4 standard also facilitates consideration of the influence of neighbouring structures. If the structure is to be located close to a large building, which is at least twice as high as the average height of its neighbouring structures, then the design should take account of the peak velocity pressure at height zn (ze = zn) above ground:

zn = 1 r for x ≤ r

zn = 1

r – 1 – 2 . hlow . (x – r) for r < x < 2r

zn = hlow for x ≥ 2r

If the height hlow > 0.5hhigh i.e. zn = hlow then increased wind velocity can be disregarded.

In other cases tests in an aerodynamic tunnel are necessary.

The turbulence intensity Iv at height z can be calculated from equation:

Iv(z) = σv = kI for zmin ≤ z ≤ zmax

Iv(z) = Iv(zmin) for z < zmin

kI – the turbulence factor – recommended value is 1.0,co – the orography factor (as described in standard p. 4.3.3),z0 – the roughness length (Table 1).

The peak velocity pressure at height z includes mean and short-term velocity fluctuations. The recom-mended rule for determination is:

qp(z) = ce(z) . qb

where: ce(z) – the exposure factor:

ce(z)=

qb – the basic velocity pressure

vm(z) co(z) . ln(z/z0)

qp(z)qb

AA380

During determination of qp calculations between different terrain roughness categories should be taken into account – if a structure with height h is situated closer than 30h from the beginning of a lower terrain category (than the one which directly surrounds the structure), then it should be assumed that structure sits within the lower terrain category.

The basic velocity pressure is calculated:

qb = 1 . ρ . vb2

ρ – air density

Wind actions on structures and structural elements shall be determined taking account of both exter-nal and internal wind pressures.

For walls and roofs with an impermeable outside skin and an impermeable, more rigid inside skin, the wind force on the outside skin may be calculated from cp,net = cpe (p.7.2.10 EN 1991-1-4).

Roofs shall be divided into wind action zones according to Figure 2, with pressure coefficients according to Table 2. The reference height for flat roof and roofs with curved or mansard eaves should be taken as h. The reference height for flat roofs with parapets should be taken as h + hp according to drawing below:

It is necessary to check all directions of wind actions, unless terrain orography or construction of the structure guarantees that action from particular direction will not occur.

3 or 4 zones are created, depending on structure size and shape, with different levels of wind action (Figure 3), respectively:

- corner zone (F);- outside edge zone (G);- inside edge zone (H);- inside zone (I).

The wind pressure acting on external surfaces

we = qp(ze) . cpe

– qp(ze) – the peak velocity pressure– ze – the reference height for the external pressure (Figure 2).– cpe – the pressure coefficient for the external pressure

Wind force Fw acting on the structure is determined by vectorial summation of the forces Fw,e , Fw,i , Ffr loads (for fastenings Fw,e only):

– external forces:

Fw,e = cscd . we . Aref

– cscd – structural factor (according to standard p.6). The following points apply:1) for buildings <15m cscd = 12) for roof elements having a natural frequency greater than 5Hz cscd = 1,NOTE: Glazing spans smaller than 3m usually have a natural frequency greater than 5Hz– we – external wind pressure (according to standard p 5.1)– Aref – reference area

The appropriate fixings quantity in individual roof zones should be determined based on the calculated Fw,e load in conjunction with the manufacturer’s fixing performance, specified in technical materials and approvals.
