Foreword Publishing information This Published Document has been prepared by BSI Subcommittee B/525/1. It is a background paper that gives non-contradictory complimentary information for use in the UK with the Eurocode BS EN 1991-1-1:2002 and its UK National Annex. This Published Document is published by BSI and came into effect on 31 May 2011. It was prepared by Subcommittee B/525/1, Actions (loadings) and basis of  design, under the authority of Technical Committee B/525,  Building and civil  engineering structures. A list of organizations represented on this committee can be obtained on request to its secretary.

Relationship with other publications This Published Document is a background paper that gives non-contradictory complimentary information for use in the UK with BS EN 1991-1-1:2002 and its UK National Annex.

Use of this document As a guide, this Published Document takes the form of guidance and recommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading. Any user claiming compliance with this Published Document is expected to be able to justify any course of action that deviates from its recommendations.

PD 6688-1-1:2011

Introduction When there is a need for guidance on a subject that is not covered by the Eurocode, a country can choose to publish documents that contain non-contradictory complimentary information that supports the Eurocode. This Published Document provides just such information and has been cited as a reference in the UK National Annex to BS EN 1991-1-1:2002.

1 Scope This Published Document is a background paper that gives non-contradictory complementary information for use in the UK with BS EN 1991-1-1:2002 and its UK National Annex. This Published Document gives non-contradictory complementary information relating to imposed loads on floors for areas of industrial use and other work area use.

2 Imposed loads on floors for areas of industrial use and other work area use BS EN 1991-1-1:2002, 6.3.2.2 does not specify values for imposed loads on floors for areas of industrial and other work area use (i.e. category E2 from BS EN 1991-1-1:2002, Table 6.3). However, BS EN 1991-1-1:2002, 6.1  (4) does state that loads for heavy equipment (e.g. in communal kitchens, radiology rooms and boiler rooms) should be agreed between the client and/or the relevant authority. In the absence of such agreement, the minimum imposed loads given in Table 1 may be used for category E2 loaded areas.

3 Vertical loads on partition walls and parapets BS EN 1991-1-1:2002, 6.4 does not specify values for vertical loads on parapets. The following guidance may be used. For all types of activities given in Table NA.8, the parapets, should be designed for a vertical load. This vertical load should be either a concentrated load of 1 kN or a uniformly distributed load of 0.6 kN/m, whichever gives the worst design condition in combination with the recommended horizontal loading of Table NA.8. This combination of loads should be taken into account in the design of relevant elements of the structure that support the parapets.

4 Uniformly distributed and concentrated loads applicable to infills for walls and parapets BS EN 1991-1-1:2002, 6.4 does not specify values for vertical loads on parapets. The following guidance may be used. The uniformly distributed line loads give in BS EN 1991-1-1:2002, Table NA.8 and the uniformly distributed and concentrated loads applicable to the infill are not additive and should be considered as three separate load cases.
