Why, if arch’s are the best for bearing loads are the majority of modern structures made with using 90 degree angles?

Seems like they would be better for areas with earthquakes, hurricanes, and high wind while also being more durable in general.

Arches are great in static compression, but an earthquake can make them crumble.

Once you start adding rebar for stability and tensile strength, it is more efficient to make multiple levels with columns and beams and slabs. Arches are still pretty good if doing only one big space.
