Example 3 16 design of a cantilever retaining wall bs 8 110.
Cantilever wall concrete reinforcement.
Strength and compaction of concrete.
It has much thinner stem and utilize the weight of the backfill soil to provide most of the resistance to sliding and overturning.
They are most frequently used for roads bridge abutments and other built facilities.
Reinforced concrete cantilever retaining wall analysis and design aci 318 14 reinforced concrete cantilever retaining walls consist of a relatively thin stem and a base slab.
φfb depends on type and condition of reinforcing bar.
Coefþcient of friction is 0 4 and the unit weight of reinforced concrete is 24 knm 3 1.
Reinforced concrete cantilever retaining walls are one of the most commonly used structures in the field of civil engineering with numerous applications.
In this study the cantilever earth retaining wall was chosen.
Grade of concrete is m20 and steel is fe415.
Reinforced cement concrete retaining wall cantilever type information reinforced cement concrete retaining wall cantilever type maximum 6 0 meter height including column load in line.
3 2 stepped cantilever retaining wall the stepped cantilever wall is new type suggested in this thesis.
Sbc of soil 200 kn m3 and coefficient of friction between concrete and soil 0 45.
Design the wall and base reinforcement assuming fcu 35 knm 2 f y 500 knm 2 and the cover to reinforcement in the wall and.
Take density of soil 18 kn m3.
The base is divided into two parts the heel and toe.
Generally the conventional design of reinforced cantilever retaining wall is very.
Determine the factors of safety against sliding and overturning.
An average design ultimate bond stress φfb is assumed at the interface between the concrete and the reinforcing bar φ 0 6.
Retaining walls are utilized in the formation of basement under ground level wing walls of bridge and to preserve slopes in hilly terrain roads.
The steel reinforcement provided is in the form of two legged stirrups of required diameter steel.
The saving in steel reinforcement can be done as per curtailment reduction in number of stirrups from bottom to top side of wall.
Cantilever retaining wall is the most common type of earth retaining structure.
A design retaining wall and show all stability checks.
The stem may have constant thickness along the length or may be tapered based on economic and construction criteria.
B draw reinforcement details of toe and stem with curtailment of reinforcements.
Cantilever retaining wall are usually of reinforced concrete and work on the principles of leverage.
Cantilever walls of reinforced concrete are still fairly common in urban areas because they are less susceptible to vandalism and often do not require select backfill.
