Masonry Block Retaining Wall Design Example

Sketches of the retaining wall forces should be considered to properly distinguish the different forces acting on our retaining wall as tackled in the previous article retaining wall.

Masonry block retaining wall design example.

Concrete masonry units concrete blocks manufactured to provide an attractive durable stable face to a retaining wall. Traditional retaining wall solutions can be expensive and restrictive for example cast in situ construction is slow and expensive to build and precast retaining wall panels are restricted in height. Example design the reinforced concrete masonry cantile ver retaining wall shown in figure 2. Despite the many references a single volume on retaining wall design for the professional practitioner and civil engineering student could not be found.

The self weight of the srw system is either the weight continue reading. Masonry gravity retaining walls relying on gravity loads to resist the overturning. An information series from the national authority on concrete masonry technology ncma tek 15 5b 1 segmental retaining wall design introduction segmental retaining walls srws function as gravity structures by relying on self weight to resist the destabilizing forces due to retained soil backfill and surcharge loads. Conditions and wall geometry n a design example which demonstrates the use of the australian standard and.

Assume level backfill no surcharge or seismic loading active earth pressure and masonry laid in running bond. 4 foot 1 2 m high gravity retaining wall equivalent fluid pressure of soil 30 pcf 4 7 kn m soil weight 100 pcf 15 7 kn m soil friction coefficient 0 55 soil bearing capacity 2000 lb ft 0 096 mpa 100 solid concrete masonry units 120 pcf 18 9 kn m concrete footing 150 pcf 23 6 kn m. 305 mm f m 1 500 psi 10 3 mpa assumed weights. The coefficient of friction between the footing and foundation soil k 1.

Wall thickness 12 in. Assume level backfill no surcharge or seismic loading active earth pressure and masonry laid in running bond. Masonry design and in all sorts of related topics. Let s take a fresh look and see how concrete interlocking blocks or more commonly known as concrete lego blocks can be used as the solution.

The coefficient of friction between the footing and foundation soil k 1 is 0 25 and the allowable soil bearing pressure is 2 000 psf 95 8 kpa ref.
