Masonry Block Retaining Wall Design Example

Wall thickness 12 in.

Masonry block retaining wall design example.

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. Despite the many references a single volume on retaining wall design for the professional practitioner and civil engineering student could not be found. The coefficient of friction between the footing and foundation soil k 1. The self weight of the srw system is either the weight continue reading.

Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. Example design the reinforced concrete masonry cantile ver retaining wall shown in figure 2. Masonry design and in all sorts of related topics. 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 gravity retaining walls relying on gravity loads to resist the overturning. Assume level backfill no surcharge or seismic loading active earth pressure and masonry laid in running bond. Hence this attempt to condense simplify and compile information from many sources including my own experience into this book. 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. Assume level backfill no surcharge or seismic loading active earth pressure and masonry laid in running bond. Design the reinforced concrete masonry cantilever retaining wall shown in figure 2. Conditions and wall geometry n a design example which demonstrates the use of the australian standard and.

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.
