Problem #1

Given: diagram of slab bridge

25 psf fws asphalt

1 ft 7 in

reinforced concrete

typical bridge section

for information only

DL of barrier loading = 0.331 klf

DL of slab (1.5835')(0.150 kcf) = 0.238 ksf

future inner? ring? surface (fk/s) = 0.025ksf

Max live load moment = 18.4 kift

Max dead load moment = 21.4 kift

Find: the area of reinforcement if the d for this reinforcement is 16.5" in a 12" wide beam.

Problem #2

Given: diagram

assume: bearings @A=B?

Find: the allowable shear stress of a hollow shaft ABCD, knowing I.D. = 40mm. The radius of disk B is 80mm the steel is A36 with allowable shear stress of 100mpa

= 166mpa

150 mm

150 mm

T = 600 klm?

Problem #3

Given: Timber beam with cross section

Rope tie

4'

8"

4'

5 kips

8"

6"

Section of beam

Beam DL load weight is 12 pLf

Find:

a) the force in DB

b) Determine the normal shear stress at the three points noted including beam Dead Load.
