QUESTION:
(1)Design of cantilever retaining wall wall and base
reinforcement
(2)Plotting moment capacity diagrams
The #7 steel bar is used as the main bar, and the #4 steel bar
is used as the temperature and shrinkage bar
#7: f= 2.22 cm, As = 3.87
cm2 ; #4: f=1.27 cm, As
= 1.29 cm2
Ka = 0.30 Kp = 0.33 q=1.95
t/m2 γm = 1.6
t/m3 f¢c = 210
kg/cm2；fy = 4200
kg/cm2 Ld = 60 cm
The maximum shear force and bending moment are calculated at
points A and B, and the thickness of the protective layer of the
steel bar = 5 cm (excluding the radius of the steel bar)
Wu=1.2WD+1.6WL
