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).
