A knee wall is a short wall, typically under three feet (one metre) in height, used to support the rafters in timber roof construction. In his book A Visual Dictionary of Architecture , Francis D. K. Ching defines a knee wall as "a short wall supporting rafters at some intermediate position along their length."
In military engineering, earthworks are, more specifically, types of fortifications constructed from soil. Although soil is not very strong, it is cheap enough that huge quantities can be used, generating formidable structures. Examples of older earthwork fortifications include moats, sod walls, motte-and-bailey castles, and hill forts.
Soil may be stabilized by the addition of lime or cement, and may be compacted into rammed earth. Construction is faster with pre-formed adobe or mudbricks, compressed earth blocks, earthbags or fired clay bricks. [a] Types of earth structure include earth shelters, where a dwelling is wholly or partly embedded in the ground or encased in soil.
With a geotextile on one side it makes an effective drain on the backfilled side of retaining walls, basement walls and plaza decks. The cores are sometimes vacuum formed dimples or stiff 3-D meshes. As with wick drains, the geotextile is the filter/separator and the thick polymer core is the drain.
The walls must resist the lateral pressures generated by loose soils or, in some cases, water pressures. [3] Every retaining wall supports a "wedge" of soil. The wedge is defined as the soil which extends beyond the failure plane of the soil type present at the wall site, and can be calculated once the soil friction angle is known. As the ...
When my family moved to New Hampshire going into my freshman year of high school, Dr. C. Everett Koop, President Ronald Reagan’s surgeon general, became my neighbor. As an aspiring doctor, I ...
Shallow foundations of a house versus the deep foundations of a skyscraper. Foundation with pipe fixtures coming through the sleeves. In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water (as with floating structures), transferring loads from the structure to the ground.
Health insurance industry officials remain uncharacteristically reserved in the aftermath of the fatal shooting of UnitedHealthcare CEO Brian Thompson on Dec. 4.. A week after the attack, the ...
