The tires were finished off with a cement bond beam
that framed 2 x 6 walls are anchored to.
For earthquake resistance, the walls are built over a grid of steel reinforcing bars that extends into a concrete bond beam
(a reinforcing beam capping the walls), which is left exposed as a design element throughout the house.
In load bearing (or Nebraska style) construction, some folks still like to use a lath, securely fastened to the footer and the bond beam
, asserting that the strength of the wall is then in the stucco.
Artificial boulders often notch over the edge of a pool, resting on and tying to the perimeter bond beam
(the structural beam that rings the pool) and running several feet below the water level.
One couple has revived and updated this building tradition for their new home (shown at left), combining adobe bricks with a wall-topping bond beam
(a steel-reinforced concrete collar) for extra structural strength.
The bond beam
can bear the weight of the extended walls, or it can dip below water level, where it can support the weight of large boulders that give some of these pools a natural look.
Behind the spa and along the end closest to the wall, the pool's bond beam
was extended 12 inches.
Around the one with the small waterfall (page 57), the lowest level of boulders was set into a lowered pocket in the bond beam
Steel-reinforced top bond beams
, concrete studs and footer beams
of Dow Styrofoam, insulated corners and bond beams
, plus drywall-ready galvanized steel studs.
com)-- The Guide is the result of a four-year research and test programme to evaluate reinforced, full-size walls strengthened against lateral load and provides guidance and recommendations for the design of masonry walls incorporating bond beams
