At what temperature do steel beams melt, And what temperature is jet fuel when exposed to fire. The jet fuel temperature is not
hichkok12 [17]
When burning, Yes.

A normal fire in a steel-frame building can soften the structure to the point of collapse.


Building laws / regulations require that all the structural steelwork is either covered in a protective coating (such as intumescent paint) or boxed in with fire-resistant plaster, so the fire can be extinguished before the building is weakened - or at least give people time to get out.

If that coating or plaster is damaged by impact or an explosion, the steel is exposed and the building can collapse relatively quickly.

(The common intumescent coatings just look like paint until exposed to fire, so the steelwork may appear to have no particular protection - but it always does).

Information:
http://www.steelconstruction.info/Fire_p...

See the images below - small buildings with steel-frame roofs after fires; you can see the amount of "sagging" and distortion on structures that have no particularly high loads.
These have burned long enough to destroy any protection, or they did not have any as the structure does not support occupied space.

Celia's impact on early intervention success could be determined through:
Kaylis [27]

The correct answer is experimental research. There are few successful early interventions on a meaningful scale, seemingly due to a lack of learning and information sharing across local authority areas, and the failure to robustly evaluate many government and charity interventions. Expert interviews suggest that practice varies significantly by local authority area, and there is a need to identify, evaluate and scale-up interventions that work. Experts identified three main areas of early intervention to improve outcomes for children in care: 1. Supporting care leavers, including through employability and accommodation support. 2. Raising educational attainment. 3. Mental health and emotional wellbeing support. Supporting the transition out of care is the area at which most initiatives are targeted. There is a need for more upstream support to contribute to improving outcomes for care leavers, for example, supporting improved educational attainment.
