Design for fire

What is the meaning of time equivalent in fire engineering?

It is the severity of a fire in a compartment in terms of exposure to a standard fire test
It is the time in minutes at which the fire in a compartment will burn above 600°C
It is the period for which a fire will burn based on times measured in other, equivalent, compartments
It is the period of time which is required for the fire brigade to attend and extinguish a compartment 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

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

Boards
Sprays
Thin film intumescent coatings
Flexible blankets

Structural steel in single storey buildings does not generally require fire protection. Which of these situations is not an exception to that rule?

The steel is in an external wall which must retain stability to prevent fire spread to adjacent buildings
The steel forms part of a compartment wall or the enclosing structure of a protected zone
The building contains a valuable cargo which must be protected and so the building must be protected against collapse
The steel forms part of a separating wall

How does an element of construction demonstrate that it can perform a fire resisting function if required?

Through trial and error in real building fires
Through a detailed theoretical study
Via a fire test carried out in accordance with a standard acceptable in the country in which that element is to be used
Via tests carried out in the manufacturer's own furnaces

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

In which areas of the UK are sprinklers not mandatory in buildings over 30 metres in height?

England & Wales
Scotland
Northern Ireland
All of the above

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 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.
