Design for fire

The maximum period of fire resistance required in the documents published by Government across the UK to help meet the requirements of their Building Regulation is?

60 minutes
90 minutes
120 minutes
240 minutes

Where a single storey building must retain stability to prevent fire spread to adjacent buildings (i.e. a boundary condition), the most efficient method of designing is usually to?

Fire protect the whole building
Fire protect the stanchions along the affected wall(s) and design the bases to resist the overturning moment from collapse of the unprotected rafters
Fire protect selected frames of the building
Rely on the owner of the adjacent building to install cladding capable of resisting the fire spread

A new British Standard, BS 9999, has been published to provide an alternative approach to the design of fire precautions in buildings to those in Government published documents. Does BSI describe it as being?

Based on structured risk based design
Based on conservative experience
Based on European approaches to the design of fire precautions in buildings
Based on an averaged approach from across the regions of the UK

Which of the following is not a correct conclusion following the Cardington fire tests?

That composite steel deck construction has significantly greater reserves of strength than is indicated by tests of individual members
That columns are critical stabilising elements and must be protected
That all beams supporting composite steel deck floors do not need to be protected in order to prevent structural collapse in fire
That the results are applicable to forms of construction other than steel frames with composite steel deck floors.

The dominant mechanism which enables a composite steel deck floor to enhance its load carrying capacity at large deflections is based on what?

Tensile membrane action in the slab
Catenary action in the beams
Robust connections
Thermal gradients in the slab

Which of the following statements is not always correct?

Fire safety engineering can provide an alternative approach to fire safety to that given in Government published documents such as Approved Document B.
A fire engineering approach should always be considered in large buildings.
For some buildings, the provisions of documents such as Approved Document B for the design of fire precautions may not be adequate and a fire safety engineering approach may be the only viable way to a satisfactory standard of fire safety
Fire safety engineering has wide applications in finding solutions to particular problems in the design of fire precautions

Which of the following is/are true?

Approved Document B must be used in the design of fire precautions in England?
The use of Approved Document B for the design of fire precautions in buildings in England is deemed to satisfy the requirements of the Building Regulations.
It is not necessary to use Approved Document B for the design of fire precautions in England if it can be shown that you have met the requirements of the Building Regulations in some other way.
The use of Approved Document B does not guarantee that all buildings will be safe in fire

Which of the following have been used as compensatory features where beams have been designed to be unprotected in composite steel deck construction?

Increased numbers of shear studs
Increased mesh size
Flexible connections to accommodate increased deflections
Changing the floor to precast plank

Which of the following is/are not considered a major risk factor in fire in BS9999, the new British Standard published to provide an alternative approach to the design of fire precautions in buildings to those in Government published documents?

Whether the occupants of the building are familiar with their surroundings.
Whether the occupants of the building are likely to be asleep
Where there is not a fire station nearby
The height of the building

Which is the most common form of structural fire protection used in the UK?

Boards
Sprays
Thin film intumescent coatings
Flexible blankets
