Crack Detection

Concrete materials are meant for supporting structures, building foundations and they act as several load-bearing structures. Over time, due to environmental conditions, and based on the constituent materials used, concrete materials are subjected to a great degree of distress. Corrosion of the reinforcement bars due to chemical influences, uneven base, earthquake, drying shrinkages, and alkali-aggregate reactions are some of the reasons for concrete distress.

Select the correct statement from the following: An "under-reinforced" beam condition results in a brittle failure mode. An "over-reinforced" concrete beam is acceptable because it's stronger than required and is conservative. An "over-reinforced" beam corresponds to a condition where the beam maximum bending strength is controlled by steel yielding. The ACI code provisions include a maximum limit on the amount of beam reinforcing steel to ensure that an "under-reinforced" condition exists.

Using a simply supported pre-stressed concrete beam, explain the following status using stress diagrams: Stress condition due to pre-stress alone. Change of stress conditions due to the increment of external load: Decompression moment (bottom fibre compression = 0); Cracking moment (tensile strength develops at the bottom and starts cracking at the bottom); and Balance state (whole section is at an equal amount of compression).
