alleryStart learning →Per §7.6.3, creep of concrete is best defined as the:
AReduction in volume due to drying alone
BIncrease in strain under sustained constant stress
CElastic recovery on unloading the specimen
DInstantaneous strain at the moment of loading
Answer & Solution
Correct answer: B. Increase in strain under sustained constant stress
1. §7.6.3 reads: 'Creep can thus be defined as the increase in strain under a sustained stress and since this increase can be several times as large as the strain on loading, creep is of considerable importance in structural mechanics.'
2. Under constant strain instead, creep manifests as stress relaxation.
