Floor slabs frame into it at 3 2m centres and are 200mm thick.
Reinforced concrete wall design example.
In this example the structural design of the three retaining wall components is performed by hand.
Ce 537 spring 2011 retaining wall design example1 8.
This is a coupled wall running in the transverse building direction.
Reinforced concrete stocky wall is where the effective height he divided by the thickness h does not exceed 15 for a braced wall and 10 for an unbraced wall.
When depth is large it is called rc wall.
Design is similar to a rc column breadth equal to thickness of wall and depth equal to 1m.
Reinforced concrete wall is classified as.
A 20m high 3 5m long shear wall is acting as both a lateral and vertical support to a 4 storey building.
There are 6 columns between it and the next shear wall.
2 5 clear to strength steel 5 12 rather than the designed 5 10 bending strength of the section has been reduced by about 16.
Strength reduced from 136 7 to 114 9 in kips.
The structure in this design example is a six story office building with reinforced concrete walls as its seismic force resisting system.
305 mm thick concrete masonry foundation wall 12 ft 3 66 m high.
Two equations are developed.
Rcc wall is.
Using table 4 the wall can be adequately reinforced using no.
Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.
The example focuses on the design and detailing of one of the reinforced concrete walls.
Ce 437 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions.
Design the reinforcement in the wall at its base and mid height.

In this example the structural design of the three retaining wall components is performed by hand.
Plain concrete wall when reinforcement 0 4.
Slender wall is a wall other than a stocky wall.
Design a reinforced concrete retaining wall for the following conditions.

Equivalent fluid pressure is 45 psf ft 7 0 kn m m excluding soil load factors 10 ft 3 05 m backfill height.
The analysis and design of reinforced concrete shear wall as shown in this example is essential to lateral load resistance for wind and seismic forces.
Load from slab is transferred as axial load to wall.
