b) Cantilever
c) Simple Arch
d) Frame

Answer 1

A corbeled arch is an arch where the beams are shaped like an arch and the ends simply rest on walls. It is constructed by offsetting successive courses of stone (or brick) at the springline of the walls so that they project towards the archway's center from each supporting side, until the courses meet at the apex of the archway.

Step-by-step explanation:

In a corbeled arch, the beams are shaped like an arch and the ends simply rest on walls. The corbel arch is constructed by offsetting successive courses of stone (or brick) at the springline of the walls so that they project towards the archway's center from each supporting side, until the courses meet at the apex of the archway. The corbel arch was often used in conjunction with a relieving triangle, which helped redistribute weight from the lintel to the supporting walls.
