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).

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.

<span>If you want to have just one map wherein all the information
you require about a certain place and its political make-up it would be an
advantage to just have it all in one map since all the information you needs is
all there. This comes handy when you want
to travel light. However, if you want to
be more specific in what you need to find then it’s best to place the physical
and political elements of the maps or makes separate maps for each element. It makes it easier to read especially when
you are looking for a specific element.</span>
This definition of law is known as legal positivism.This philosophy lays a greater emphasis on the conventional nature of law and it is associated with positive norms which are made by the legislatures.Afterward, these laws are considered as common laws which must be enforced.
Answer:
Allan Sandage
Explanation:
Allan Sandage is an american astronomer that has undertaken extensive efforts to evaluate Hubble's constant rate of universe expansion.
in the beginning of his career in 1958 , the primary focus of Allan is to evaluate the Hubble's constant rate.
He used many different techniques to determine the distance to several galaxies. From these many different calculations, average value of Hubble's constant was about 50 km/sec/megaparsec.
Answer:
d. shaping
Explanation:
According to my research on various behavioral techniques, I can say that based on the information provided within the question the reinforcement technique being used by Tamika's father is called Shaping. This is a procedure that involves reinforcing behaviors that are closer to the target behavior, like in this case her father praises her every step closer she gets until she finally learned how to tie her shoes.
