Analysis :-

• Check Shear Capacity
• The Minimum Reinforcement Ratios Are Given By Aci 318-02 Section 21.7.2.1 And Section 14.3
• The Proposed Spacing Is Less Than The Maximum Permissible Value Of 18 In And Is Satisfactory. Since Wall Vu
• One Curtain Reinforcement Required. (Aci 318-02, Sec.21.7.2.2)
• The Design Shear Force Is Given By Aci 318-02 Section 21.7.4.1 & 21.7.4.4 As

Check Flexural & Axial Capacity
The Maximun Design Axial Load Strength, Aci 318-02, Sec. 21.7.5.1 & Eq.(10-2), Is
F Pmax =0.8 F [ 0.85 Fc’ (Ag – Ast) + Fy Ast] =
Where F = 0.65 (Aci 318-02, Sec.9.3.2.2)
Ag = 6240 In2.
Ast = 112.24 In2.
The Design Moment Capacity At Maximum Axial Load Strength Are From 0 To 30305 Ft-kips.

For The Balanced Strain Condition Under Combined Flexure And Axial Load, The Maximum Strain In The Concrete And In The Tension Reinforcement Must Simultaneously Reach The Values Specified In Aci 318-02 Sec. 10.3.2
As Ec = 0.003 And Et = Fy / Es = 0.002069 . The Depth To The Neutral Axis And Equivalent Rectangular Concrete

Check Boundary Zone Requirements
An Exemption From The Provision Of Boundary Zone Confinement Reinforcement Is Given By Aci Section 21.7.6.2,
21.7.6.3, And 21.7.6.5(A) Provided That
