Confined masonry, if built correctly, performs very well in earthquakes.

It uses the same materials found in reinforced concrete framemasonry construction, i.e. concrete and brick. However it uses a different construction sequence and design.

In the reinforced concrete framemasonry the RC frame carries the seismic load and the bricks are simply infill. In confined masonry (brick and mortar) walls carry the seismic loads and reinforced concrete is used to confine the walls.

It is claimed that well-constructed confined masonry buildings have been observed to incur little or no damage in moderate to even severe earthquakes.
