### Concrete Crushing An Overview Sciencedirect Topics

Aug 07 2010 As the theoretical maximum concrete strain 000383 is larger than the concrete crushing strain of 0003 this means that concrete crushing will precede plate debonding Therefore the strain profile needs to go through points C and B in Fig 713

### Crushing Strain An Overview Sciencedirect Topics

Pivoting about the debonding strain of db 002 showed that the maximum concrete strain was greater than its crushing capacity of 0003 Hence the pivotal point was changed to that of the crushing strain This gave a moment capacity of 403 kNm with a strain in the reinforcing bars of 00061 and that at the top of the plate of 00044
