The Shard - Structural fire engineering

The presentation described how factors that can affect fire intensity and structural performance in the building were varied. Which of the following were included?

Medium and high fire loads
High and low levels of ventilation
Short and long duration fires
All of the above

Which of the following accurately describes real fire behaviour in buildings?

When ventilation conditions and heat losses come into equilibrium, a steady state burning phase takes place.
Fire load in compartments is finite and a steady state burning phase continues until the fire load is practically all burnt out and the atmosphere temperature starts to decay.
The temperature and duration of a fire in a building is hugely influenced by the amount of ventilation available.
All of the above

Having listened to the presentation, which of the following statements do you think is/are true?

Most people who die in fire do so as a result of smoke inhalation
If a fire in a building reaches a stage where the structural fire protection has to do its job, it indicates that there has been a systemic failure of significant elements of other parts of the overall fire precaution strategy.
Compartmentation is an important part of any fire strategy, not only to protect escape routes but also to contain the fire to the floor of fire origin and prevent spread of fire.
Structural collapse is a major cause of deaths in fire

Which of the following were part of the fire performance solution agreed for the Shard?

On the steel framed floor, 90 minutes fire resistance on the primary beams with no protection to the secondary beams. 120 minutes fire resistance to the columns.
The transfer truss protected assuming a lower than default failure temperature to achieve 120 minutes fire resistance
Fire protection to the exposed concrete floors
An unprotected spire

Which of the following were considered to be factors in deciding whether exposed concrete is likely to spall?

Moisture content
Aggregate type
Loading regime
All of the above
