Q1:

The structure which is subjected to an imposed load after 72 hours for a period of 24 hours, is deemed to be unacceptable if it fails to recover the net deflection less than

A 90%

B 85%

C 80%

D 75%

ANS:C - 80%

If within 24 hours of removal of the imposed load, the structure does not recover at least 75 percent of the deflection under super imposed load, the test may be repeated after a lapse of 72 hours. Structures shall be deemed to be unacceptable.
