This European Standard shall be given the status of a national st
17、andard, either by publication of an identical text or by endorsement, at te latest by June 2002, and conflicting national standards shall be withdrawn at the latest by June 2002. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bou
18、nd to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Soain, Sweden, Switzerland and the United Kingdom. 3 EN 13031-1:2001(E) Introduction Part 1 of this standard relate
19、s specifically to greenhouses used for the professional production of plants and crops where human occupancy is restricted to low levels of authorised personnel. Other parts of this European Standard are to be prepared that relate to greenhouses where general access by the public is permitted (such
20、as those in garden centres or expositions), and to small domestic greenhouses. This European Standard gives rules for structural design and construction of greenhouse structures for the professional production of plants and crops. It is based on ENV 1991 “Eurocode 1 : Basis of design and actions on
21、structures“ as regards the general prin- ciples and requirements for actions, mechanical resistance and stability, serviceability and durability considerations. For structural design considerations, it is similarly based on the relevant parts of ENV 1992 to ENV 1999 (Eurocodes 2 to 9). Complementary
22、 information is provided to account for the particular requirements, functions and forms of commercial production greenhouses that distinguish them from ordinary buildings. Amongst the distinguish- ing functional requirements of greenhouses are the desire to optimise solar radiation transmission to
23、create and maintain an optimal environment for the growth of plants and crops, and commonly, to support the weight of growing plants. These have implications on the form and structural design of commercial greenhouses. Greenhouse designs, based on this European Standard providing specific informatio
24、n about load distributions, deformation criteria and tolerances, adapting rules of Structural Eurocodes, ENV 1991 to ENV 1999, result in adequate structural safety. This is justified because in contrast to normal buildings, greenhouses have specific design working lives and human occupancy is restri
25、cted to low levels of authorised personnel. As rules and requirements of this Standard may become adopted by other European Standards, for example the Structural Eurocodes or codes for Glass in Building - Design of glass panes, these will be replaced by a reference to the adopting European Standard.
26、 Design criteria for the accessibility of the greenhouses, e.g. ascents, workways, walkways, or roof ladders may be part of national legislation. 4 EN 13031-1:2001 (E) 1 Scope This European Standard specifies principles and requirements for the mechanical resistance and stability, serviceability and
27、 durability for design and construction of commercial production greenhouse structures irrespective of material, including their foundations, for the professional production of plants and crops. Fire resistance-related aspects are not covered in this standard. 2 Normative references This European St
