" I think you mean " In order to counteract the pressure differential between the weak Martian atmosphere and the relatively high pressure inside the structure, it is shaped like a hyperboloid, distributing expansion forces through the structure. ""

" What do you mean by "In order to resist the strong pressure of Mars's atmosphere, the structure is shaped like a hyperboloid, directing forces downward."?---->The highest atmospheric density on Mars is equal to the density found 35 km above the Earth's surface. The resulting mean surface pressure is only 0.6% of that of the Earth (101.3 kPa)."
