You would be shredded BEFORE it collapses.
As an example, using the picture posted by Mobius, a skilled tank crew would first use HE on SQ (superquick or instantaneous fuse) against the roof area. This would result in a HE burst right against the roofing material. Roofs are not very sturdy compared to walls. The resulting explosion would not only open the roof area, but the deadly side of the shell, that is the part that produces fragmentation, would shoot this DOWN through the attic and into the house itself. Anyone up in the attic, even a sniper with a loophole and a reinforced area, would feel compromised and in danger. Certainly suppressed.
A skilled tank crew would also use AP against a building that is producing firepower. A dead giveaway is flashes and smoke/dust from firing weapons. AP would just punch through both sides of the building. Contrary to some bad threads at other web-sites, the small HE charge in a AP shell does not go off when it peirces something like a building wall. It takes quite a decel.
A skilled tank crew could also skip HE right in front of the building with the fuse on delay. This results in a fine holing of the walls of the building followed by a devastating internal blast and fragmentation effect of the interior of the building. The fragments would be directed upwards into higher floors/attic and also into the basement.
Any internal blast of HE can and will cause fires on combustible materials.
MG fire from AFVs is usually directed in long bursts. 50 rounds or so. The tracer and incindiery effect can cause fires. Armor usually uses jacketed or AP MG ammunition. Light construction buildings would not offer much protection.
Are these fuse settings modern? Or WWII? Did both the Germans and the Soviets have them?
