The hand solution is used for a detailed comparison with the analysis and design results of the engineering software program spwall.
Reinforced concrete wall design example.
Design a reinforced concrete retaining wall for the following conditions.
Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.
Ce 537 spring 2011 retaining wall design example1 8.
In this example the structural design of the three retaining wall components is performed by hand.
Two equations are developed.
Design concrete shear stress in wall section for out of plane bending.
Reinforced concrete wall when reinforcement 0 4.
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.
The structure in this design example is a six story office building with reinforced concrete walls as its seismic force resisting system.
Slender wall is a wall other than a stocky wall.
Equivalent fluid pressure is 45 psf ft 7 0 kn m m excluding soil load factors 10 ft 3 05 m backfill height.
M 29 at 1 829 mm.
Rcc wall is.
There are 6 columns between it and the next shear wall.
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.

305 mm thick concrete masonry foundation wall 12 ft 3 66 m high.
A 20m high 3 5m long shear wall is acting as both a lateral and vertical support to a 4 storey building.
F c 3000 psi fy 60 ksi.
Floor slabs frame into it at 3 2m centres and are 200mm thick.
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.
Development of structural design equations.
Design is similar to a rc column breadth equal to thickness of wall and depth equal to 1m.
This is a coupled wall running in the transverse building direction.
Using table 4 the wall can be adequately reinforced using no.
In this example the structural design of the three retaining wall components is performed by hand.
Reinforced concrete wall is classified as.
The example focuses on the design and detailing of one of the reinforced concrete walls.
9 bars at 72 in.
Load from slab is transferred as axial load to wall.
Two equations are developed in this section for determining the thickness reinforcement required to resist the bending moment in the retaining wall components stem toe and heel.
When depth is large it is called rc wall.
