#5 bars @ 24" o.c.

fy = 60,000 psi

Es = 29,000,000 psi

f*m = 1350 psi

Em = l000f'm 1,350,000 psi

Ev = 0.4Em = 540,000 psi.

(2) *Problem. *Design the given shear wall to withstand the shear and axial forces applied.

(3) *Solution. *The design procedure involves determining the rigidities of each segment (pier) within the

shear wall. The method used is based on the deflection charts of figure 7-5. The horizontal loading is then

proportioned to each segment based on its rigidity relative to the other segments, with longer and shorter

segments receiving the greater load. Each wall segment will then be analyzed by checking the flexural, axial,

and shear stresses.

the shear wall segments. The method used in determining the relative rigidities is similar to the procedure

followed in design example 1.

A solid wall containing ABCDE with no openings is assumed fixed at the bottom only. The deflection and

rigidity are determined (use rectangular pier cantilever curve #4 from figure 7-5) as follows:

The deflection of the solid bottom strip, 7.33 feet high, containing BCDE is determined (use rectangular pier

cantilever curve #4 from figure 7-5) as follows:
