---------

QUESTION 4

One of the most fundamental assumptions of reinforced concrete design is

Group of answer choices

there is always some slippage between the concrete and the steel

there is a moderate bond between the concrete and the steel

the steel and concrete do not generate a great bond

that perfect bonding exists between the concrete and the steel

Answer 1

1) The ability of the material to contonue to deform under constant load is defined as the creep. Creep is the function of time. It last for years, creep is due to the auatained loads, and it is the one of the property of the hardened concrete.

So 2^nd option is correct.

2)Dia of the No.8 bar is 1.0 inch so 3^rd option is correct.

3) The web reinforcement is rovided in the concrete beams is to bear the shear of the structure. Web reinforcement can be vertical stirrups, inclined stirrups, bent up bars etc.

From The given option vertical stirrups is the correct answer. So option 1 is correct .

Temperature steel is provided to overcome the temperature and shrinkage stresses.the temperature steel is usually provided in slabs.

Mesh steel ia provides in slabsat the xorner to avoid the lifting up of the slab.

4) it ia assumed that there is a perfect bond between the steel and concrete, ao no slippage will occurs. So 4^th option is correct.
