Design criteria for the accessibilty of the greenhouses, e.g. ascents, workways, walkways, on roofladders, are not a normative part of this standard. The specifications given in the informative annex G arerecommendations.10 Actions on greenhouses10.1 General10.1.1 All actions and influences likely to occur during the minimum design working life of the greenhouseshall be considered in the design in accordance with the procedures described in ENV 1991-1. In thefollowing subclauses of this clause these procedures are adapted for greenhouses.10.1.2 The minimum reference periods (recurrence intervals) and annual probabilities of exceedance fordetermining the characteristic values of the variable actions to be used in the design of each Class ofgreenhouse shall be as shown in Table 4.Table 4 - Minimum reference periods for actions and annual probability of exceedence of actionsGreenhouse ClassA15 and B15A10 and B10B5Minimum reference period for actions15 years10 years5 yearsAnnual probability of exceedance ofactions corresponding to the minimumreference period0,070,100,20NOTEProbability of exceedance of thereference period actions during the minimumreference period0,640,650,6710.1.3 The selected design situations shall be considered and critical load cases identified. For each criticalload case, the design values of the effects of combinations of actions shall be determined.10.1.4 Rules for the combination of independent actions in design situations are given in the followingsubclauses of this clause. Actions which cannot occur simultaneously, for example, due to physical reasons,should not be considered together in combinations.The combinations of actions to be considered in design are to be taken from 10.2.SIST EN 13031-1:2004

shall be as given in annex E.NOTE Partial factors are related to the safety level of the greenhouse. This safety level may be lower than for normalbuilding structures because human occupancy is restricted to low levels of authorised personnel.10.3.2 Combination coefficientsCombination coefficients
shall be as given in annex E.NOTE Combination coefficients depend on the combinations of actions for greenhouses. Combination coefficients aredetermined regionally due to the variation in wind, snow and seismic actions and the probability of simultaneous actionoccurrences.10.4 Characteristic value of actions10.4.1 Permanent actions Gk110.4.1.1 Permanent actions are actions due to the self-weight of structural and non-structural elements,excluding the installations even if they are permanently present.10.4.1.2 Characteristic values of the self-weight of construction elements shall be assessed in accordancewith ENV 1991-2-1.10.4.2 Permanently-present installation actions Gk210.4.2.1 Permanently-present installation actions are actions due to permanently installed equipment such asthat for heating, cooling, lighting, shading, irrigation, ventilation and insulation.10.4.2.2 Characteristic values of the self-weight of fixed equipment shall be assessed in accordance withENV 1991-2-1.10.4.2.3 For Class A15 greenhouses the characteristic action due to installations for heating, shading,cooling, lighting, ventilation and insulation shall be determined in accordance with 10.4.2.2 but shall be notless than 70 N/m2 on plan area.10.4.2.4 The characteristic value of the actions due to main supply and return heating pipes shall be taken asthe self-weight of the insulated pipes when filled.10.4.2.5 Where greenhouse structures support horizontal wires and cables of shading and irrigationequipment, the effects of the forces resulting from the system and use of these wires and cables, shall betaken into account, but shall be taken not less than:- shading systems
supporting wires:250 N per wire
drive cables:500 N per wire- irrigation equipment
supporting wires:1 250 N per wire10.4.3 Wind actions Qk110.4.3.1 Wind actions are actions imposed on the structure by wind.10.4.3.2 Characteristic values of wind actions shall be calculated in accordance with ENV 1991-2-4.10.4.3.3 Annex B provides complementary information for 10.4.3.2 to take account of the special case ofgreenhouse structures.10.4.4 Snow actions Qk210.4.4.1 Snow actions are actions imposed on the structure by snow.SIST EN 13031-1:2004

For single span greenhouses without gutter Qk4may be taken equal to 0.10.4.7 Incidentally-present installation actions Qk510.4.7.1 Incidentally-present installation actions are actions of variable magnitude due to mobile equipmentsuch as gantries running on rails supported by the structure, and cleaning equipment running along the roof,including service personnel.10.4.7.2 Characteristic values of actions for moveable installations shall be assessed from data provided bythe manufacturer on the self-weight of the equipment and the maximum design action carrying capacity of theequipment. Braking and acceleration forces of transportation equipment shall be taken into account.10.4.8 Thermal actions Qk610.4.8.1 Thermal actions are actions due to temperature effects.10.4.8.2 Characteristic values of thermal actions shall be derived from the deviations in temperature, that canoccur within a 24 h period. Characteristic values for ranges in temperature are given in annex E.10.4.8.3 For Class B greenhouses, thermal actions need not be taken into account when the length and thewidth of the greenhouse are less than 150 m.10.4.8.4 H.2 gives guidance on structural detailing which accommodates the effects due to temperaturechanges.10.4.9 Seismic actions AEk10.4.9.1 Seismic actions are actions due to earthquakes.10.4.9.2 Characteristic values of seismic actions shall be assessed in accordance with ENV 1998-1-1.10.4.10 Accidental snow actions Ak10.4.10.1 Accidental snow actions are actions imposed by snow with extreme values, that cannot be treatedby the usual statistical methods used to evaluate the characteristic value.10.4.10.2 Characteristic values of accidental snow actions shall be calculated in accordance withENV 1991-2-3.10.4.10.3 Annex C provides complementary information for 10.4.10.2 to take account of the special case ofgreenhouse structures.10.4.10.4 Accidental snow actions may be adjusted for the return period in the same way as for the groundsnow action, in accordance with ENV 1991-2-3.SIST EN 13031-1:2004
