Torsion Shear
A 100kN force was applied at each different level of both the outside and the inside
bracing frame on SAP2000.The deflections resulting from each simulation is presented in
the table below.

Since deflection is inversely proportional to rigidity, the ratios obtained from these

Lateral Bracing System Connections
Factored shear resistance of bolt:
Vr = 0.60фbnmAbFu
Since Vf = 522kN
522,000N = 0.60 x 0.8 x 2 x2xAbx830MPa
Ab = 328 mm2
Therefore, structural bolt M22 is chosen with an Ab of 380 mm2
Factored bearing resistance at bolt holes:
Br = 3фbrntdFu
Br = 3x0.8x2x10x22x450MPa = 475kN< 522kN
Therefore, structural bolt M27 is chosen instead of M22.

Factored tensile resistance:
Double angle:
Tr = фuAneFu
Tr = 0.75x[19x(152-(2x27))]x450 = 628kN
2 angles x 628kN = 1256 kN> 428kN
Double angle:
Tr = фu[UtAnFu+0.6Agv(Fy+Fu)/2]
Tr = 0.75[0.6x76x19x450+0.6x150x19(350+450)/2] = 805 kN
2 angles x 805 kN = 1610 kN> 428kN

Tr = фu[UtAnFu+0.6Agv(Fy+Fu)/2]
Tr = 0.75[1x75x10x450+0.6x75x10(350+450)/2] = 388 kN> 428*0.707 =300 kN
Therefore, double angle L152x102x16 with two structural bolts M27 at each beam or

Assuming no additional runoff from contributing areas: ΔQc = 0 m2
2. Calculate dp (Base Depth)
dp = Δ
P = design storm rainfall depth (m) = 1 m
f = final infiltration rate (m/hr) = 30 mm/hr = 0.03 m/hr
T = effective filling time of base/sub bass (hr)
According to our design, 15 cm sub bass = 5 hrs
Vr = void ratio (typically 0.4)
dp = 1 – 0.03 * 5 / 0.4 = 0.625 m
3. Calculate dmax
dmax = fTs / Vr
Ts = max allowable storage time (hr) (typically 24 - 48 hrs, assuming 24
for our case)
dmax = 0.03 * 24 / 0.4 = 1.8 m > dp

Footing Design:
1. Compute factored reaction:
qsf = 1571/22 = 393kPa
2. Minimum effective shear depth - one way shear:
ab = (2-0.5)/2 = 0.75m
From Table 9.1, dv = 275mm, thus d = dv/0.9 = 297mm
3. Minimum depth - two way shear:
From Table 9.4 establish d/he based on Af/Ac
Af/Ac = 22/0.5
2 = 16
From interpolation d/he = 0.7, resulting in
dave = hc(0.7) = 350mm.
Since 3dave = 3(0.350)= 1.05m > ab = 0.75m, Cl.13.3.4.4 is not applicable.
Thus two-way shear governs.
4. Total footing depth assuming 20M bars in both directions:
tf = 350+75+20 =445mm
Use tf = 450mm (rounding it up to the next 25mm)
Note that the dave will be used for calculating the flexural reinforcement in both directions.
5. Flexural reinforcement:
Check deep beam action in accordance with Cl.10.7.1
ab/d = 0.75/(0.450-0.075-0.02) = 0.75/0.355 = 2.1 > 2, therefore no deep beam action
qsfab2 = 221 kN, from table 9.7a
As = 950mm2/m
Thus the total reinforcement is:
As = 2(950) = 1900 mm2 > As, min = 0.002(2000)(450) = 1800mm
2
6. Find maximum bar size that can be developed in distance ab-0.075 = 0.675m
From equation 9.7
max db = √f’c(ab-0.075)1000/(0.45k1k2k3k4fy) = 20M
Number of bars = 1900/300 = 6.33 - 20M bars, thus
Use: 7-20M bars BEW (bottom each way)
