What is the purpose of groin vault?
In comparison with a barrel vault, a groin vault provides good economies of material and labor. The thrust is concentrated along the groins or arrises (the four diagonal edges formed along the points where the barrel vaults intersect), so the vault need only be abutted at its four corners.
What’s the difference between a barrel vault and a groin vault?
A barrel is completely smooth without any hard edges; Imagine cutting a barrel in half lengthwise. A groin vault is distinctly curved, but it also has some angles. They both have historical significance, and they have been used in architecture for many years.
What are the disadvantages of a barrel vault?
The disadvantage of a barrel vault, however is that it exerts thrust the same way the arch does. Meaning, the vault exerts an outward thrust and thus must be buttressed along the entire length. This characteristic prevented the use of large windows as well as prevented easy circulation.
What is an annular vault?

What is a dome vault?
Domes, like vaults, evolved from the arch, for in their simplest form they may be thought of as a continuous series of arches, with the same centre. Therefore, the dome exerts thrusts all around its perimeter, and the earliest monumental examples required heavy walls.
What does a barrel vault look like?
A barrel vault is a continuous arched shape that may approximate a semi-cylinder in form, resembling the roof of a tunnel, or may be pointed at its apex. It is typically formed by a series of arches or vaults placed side by side or by a continuous shell.
Why is it called a groin vault?
It’s called a groin vault because the parts meet together in a V, like the V where your legs come together. You make a groin vault by building two barrel vaults that cross each other, so that they make an X. A groin vault can be rounded, as in Romanesque churches, or pointed, as in Gothic churches.
