When designing a bearing plinth, should anti-bursting reinforcement be provided? Under BS 5400, it was only mentioned in the section for end block anchorages of tendons. How should the code be interpreted?
BS5400 has been superseded and withdrawn, so you probably shouldn't be using it.
That said, when I last used it, I did provide bursting reinforcement for bearing plinths.
In general, just because something isn't explicitly stated, it doesn't mean you shouldn't use your engineering judgement / common sense. If you recognise the possibility of bursting failure, you need to do a design check for bursting failure. This will either tell you that reinforcement isn't needed, or give you the required reinforcement against said failure.
