Aci e702 example problems buried concrete basement wall page 5 of 9 calculations references flexure and axial design vertical reinforcement at base of wall using section 14 4 design method walls designed as compression members based on preliminary investigation try 6 bars at an 8 inch spacing 6 8.
Concrete wall design example.
Design of walls 365 and concrete in alternate flanges goes into tension.
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.
Considering cracked section moment of inertia including effective width of compression flanges does not produce too dissimilar results.

In this example the structural design of the three retaining wall components is performed by hand.
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.
F c 3000 psi fy 60 ksi o development of structural design equations.
Two equations are developed in this.
The designer must determine the reinforcement size and spacing required to resist the applied loads listed below.
