(b) From Table 6.11-1,

Viu = 5 N/mm 2

From eqn (6.11-3),

VI + V = 5

Design and detailing-illustrative example 243

where V = 0.57 N/mm 2 from Example 6.11-2(b). Therefore

VI = 5 - 0.57 = 4.43 N/mm 2

Using eqn (6.11-1),

T _ (4.43) (3502 ) [800 - 350/3J

- 2

= 185 kNm

6.12 Design and detailing-illustrative example

The following example is a continuation of Example 4.11-1.

Example 6.12-1

Complete Step 7 of the solution to Example 4.11-1.

SOLUTION

From Example 4.11-1 (Solution: Step 6),

V = 86.15 kN

V (86.15) (10 3 ) 2

V = bvd = (325) (320) = 0.83 N/mm

< (i) 5 N/mm 2 and (ii) 0.8 V/eu (= 5.1 N/mm 2 )

Therefore the overall dimensions are adequate for shear.

From Example 4.11-1 (Solution: Step 4),

As provided at interior support = 628 mm 2

~ - 628 _ O 6001

bvd - (325) (320) - . 10

From Table 6.4-1,

Hence

Ve = 0.66 N/mm 2 by interpolation

0.5vc = 0.33 N/mm 2 ; Ve + 0.4 = 1.06 N/mm 2

0.5vc < V (= 0.83 N/mm 2 ) < Ve + 0.4

Provide minimum links, using eqn (6.4-2) (see also Example 6.4-1(b»:

= O.4bvSv = (0.4) (325)sv
