In this example the structural design of the three retaining wall components is performed by hand.
Ce 537 spring 2011 retaining wall design example 1 8 design a reinforced concrete retaining wall for the following conditions.
Considering cracked section moment of inertia including effective width of compression flanges does not produce too dissimilar results.
The designer must determine the reinforcement size and spacing required to resist the applied loads listed below.
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.

Concrete strength al ൯ne for an 10 thick wall with 5 10 and 2 5 clear to strength steel will only reduce the nominal moment capacity of the secti對on from 136 68 to 135 66 inch kips 尩 if the concrete strength decreased from 3 5 to 3 0 ksi.
In this example the structural design of the three retaining wall components is performed by hand.
Two equations are developed.
To illustrate the use of the curves and formula given in figure 1 assume a building with exterior walls spanning 12 ft 3 7 m vertically between the floor and the roof is designed to resist a wind pressure of 20 psf 958 pa.
A 20 ft 6 1 m high reinforced concrete masonry wall is to be designed to resist wind load as well as eccentrically applied axial live and dead loads as depicted in figure 8.
