Question
Structural Engineering Question on Working stress and Limit state design concepts
Various stresses in jointed plain concrete pavement with slab size of 3.5 m x 4.5 m are denoted as follows :
Wheel load stress at interior = Swli
Wheel load stress at edge = Swle
Wheel load stress at corner = Swlc
Warping stress at interior = Sti
Warping stress at edge = Ste
Warping stress at corner = Stc
Frictional stress between slab and supporting layer = Sf
The critical stress combination in the concrete slab during a summer midnight is
A
Swlc+Stc
B
Swle+Ste+Sf
C
Swle+Ste−Sf
D
Swlc+Stc+Sf
Answer
Swlc+Stc
Explanation
Solution
The correct option is (A): Swlc+Stc.
