Would have snapped the back soon, as the sharp edges of the plates would have acted as tear points. The keel was strong with lifting from the bow or stern, but very weak in humping, as the plates that hold it together are not as strong in tension. That is seen as it tore in half with the stress just before sinking, when the empty stern was being lifted from the water. Making it strong enough would have cut greatly into the carry capacity, taking up a lot of the displacement.

Brittanic ISTR the major cause for the sinking was all the portholes being open, because the designers had figured out they would all be normally closed in the cold Atlantic runs, but instead she was now in the sweltering Mediterranean sea, and the ventilation was in no way designed to cool the ship, more being designed around heating up the areas that would be losing heat really rapidly to the surrounding cold water, instead of the other way round.

Yes the steel did have quality poorer than modern steel, but it all did pass the shipyard testing for tensile strength, as they did test all batches that way for all materials. That only came in in WW1 and WWII, when they used sub par steel that had high sulphur content, which made it become brittle in the cold weather of the Atlantic. However the steel did still work to absorb the energy and deform, and the rivets that failed were operated well past design spec. Yes the modern testing did show they were not as capable as the best of the day, but none of them actually were defective by the standard testing of the day, even if they would have failed when cold. But test at room temperature, around 15 to 20C ,and they passed, even if they would fail at -15C.

Well, these are still stairways up the compartment, and you simply have to climb up them in the compartment, till you will either reach a higher level where there are no watertight doors, or the deck, so then can traverse the length. In case of flooding the natural response is to get out of the water by going up, and there are plenty of stairwells to allow that.

@CodyJMinor0620 True, but also standard practice at the time. Natural to try to avoid a collision if possible, and the lack of lookout seeing the ice was more due to the cold calm water, with no moon leaving no way to see the ice at all till close by. No radar to see, and it is hard to see a dark shape against a dark sky especially if there is also a cold layer of air by the water surface, providing a refraction layer, that prevents the light from being shown to you till it is only a short distance away. Just like a mirage of the sky on a hot day in the desert, the cold layer over the ocean showed the clear ocean a distance away till you got close enough.
