Thanks Roland. That's an explanation I can accept.
Although there is no such difference for the Grade 4.6 bolt, I can accept that for such weaker bolts, the design strength (or allowable strength) for the Grade 4.6 bolt is very close to its material strength, such that the two codes had used a...
There are certain areas where the superseded codes may still need to be used, such as in the assessment of existing buildings. However, this is just something I had noticed and it's been bugging me. If anybody had come across this before and know of the reason, your help in answering the...
BS 4190 says the bolt/thread rod strength for Grade 8.8 is 640 MPa. BS 5950 says it's 560 MPa for the same material. Why the difference? There is no difference for Grade 4.6, but there is again a difference for Grade 10.9. Thanks.
