Both BS Part 8[1] and Eurocodes are available for the design of structural steel in fire in the UK. The Eurocodes suite consists of: BS EN [2], BS. Reference is also made to British Steel publication “Design Examples to BS : Part 1: (2nd Edition) on which this example is based. Table numbering. Buy BS Structural use of steelwork in building. Code of practice for fire resistant design from SAI Global.

Where test evidence is available, it might be possible to reduce the protection to the bolts of the connection. Overview Product Details BS Key 1 Concrete slab Figure C.

Except as permitted under the Copyright, Designs and Patents Act no extract may be reproduced, stored in a retrieval system or transmitted in any form or by any means? These tests should be carried out at an approved testing station and the recommendations derived from them should be prepared by a suitably qualified person.

Design using structural fire standards –

Minimum thickness of concrete for trapezoidal profiled steel sheets see Figure 8 Concrete type Minimum thickness of concrete for a fire resistance period of: The strength retention factors for bolts and welds are given in Table 4. Bss members of BSI are kept up to date with standards developments and receive substantial discounts on the purchase price of standards.

For unprotected rolled I or H sections, it may be determined from tests or, for common periods of fire resistance, from Table 9 for columns and tension members or Table 10 for beams. It should be noted that the Eurocodes have introduced the concept of section classification into fire design, something that was absent from BS Part 8 [1]. Constructions resistant au feu. The engineer should, however, be satisfied that the procedure and assumptions made are applicable to the structure in question.


NOTE For further information 5590-8 design methods, see [4]. Any specified requirements for the insulation and integrity of compartment walls and floors, including any incorporated members, should also be satisfied.

Variation of thermal conductivity with temperature for steel 6. Variation of specific heat with temperature for steel 6. BSStructural use of steelwork in building? The deflection may be ignored.

The factors in Table 1, Table 2, Table 3 and Table 4 are expressed as fractions of the room temperature design strength. The Eurocodes suite consists of: Accept and continue Learn more about the cookies we use and ns to change your settings.

Non-destructive test methods can be employed to ascertain whether the mechanical strength 9550-8 members have been unduly affected. Method for determination of the fire resistance of elements of construction general principles.

Members should be assessed on the basis of their compliance with the appropriate British Standard. Use may be made of heat shields and wired glass in adjacent windows.

BS 5950-8:2003

Fire protection for structural steel in buildings 3rd edition? In some cases, it might not be necessary to apply fire protection to bracing members and consideration should be given to: It supersedes BS Temperatures apply to I and H sections heated on three and four sides and channel sections heated on three sides Flange thickness 15 min mm C Design temperature for fire resistance period of: British Constructional Steelwork Association Ltd.


In response to orders for international standards, it is BSI policy to supply the BSI implementation of those that have been published as British Standards, unless otherwise requested.

Fire resistance of composite floors with steel decking.

One of the most common situations in which temperature gradients have a significant effect on the fire resistance of structural steel is where beams support concrete slabs.

Variation of specific heat with temperature for normal weight and lightweight concrete Figure 595-08 When this will take place is not yet clear and both codes will be available for a period of time.

Annex C normative Simplified method of calculation for beams with shelf angles C. Variation of thermal elongation with temperature for normal weight and lightweight concrete Figure 5? If it can be sb that, in the event of a fire, any external steelwork will not be heated to such a temperature as to render it unable to maintain its function, then it may be left without any protection. Am Hollow sections, circular?? Minimum thickness of concrete for re-entrant profiled steel sheets Table A.

Specification for materials, fabrication and erection: The Steel Construction Institute P BSApplication of fire safety engineering principles to the design of buildings?

Methods are given for determining the thermal response of the structure and evaluating the protection required, if any, to achieve the specified performance, although it is recognized that there bz situations where other proven methods may be appropriate. Revisions British Standards are updated by amendment or revision.
