Thanks guys. I have profis anchor but it is also based on ETAG annex c. The reason i sometimes shy away from it is because it assumes the shear capacity to be evenly distributed on the anchors and sometimes ignore the fact that only the anchors close to the edge when c<10Hef is actually supposed...
I normally design resin anchors using ETAG guidance since we are not allowed to specify a particular manufacturer to the contractor.
I am working on a bridge deck and i need to resist some forces from a barrier. I am doing this using resin anchor rebar. I have gone through all the checks...
Following to question. i will like to be a bit specific since i require the advice from you. will a 1.7m deep and 1.2 metre wide foundation of length 28metre (strip foundation) be able to withstand sliding when it is impacted with a force of 528.006kn shear force and a moment of 1246.3knm (have...
In analysing strip foundation for high containment barriers. I visualise it as; when i place a long log on the floor it is easier to move it by pushing at one than to push it in the middle. So in my design i model the strip foundation as a line beam attached to the soil springs every metre (EC...
GeopaveTraffic,
If i understood what you said. I thought you were referring to the shear plane that should be checked as indicated in EC hambly Bridge foundations and substructures. If that is the one, i have checked that since the free body diagram for that also includes the weight of the...
Apart from the horizontal force (shear force) acting on the foundation there is a corresponding moment acting in the directon of shear making failure along the plane passing below the shear key not probable. The resisting forces i have in the horizontal are therefore the frictional force at the...
A foundation has been designed for a very high containment barrier on the depature of a bridge. Because the size of foundation is too small to resist sliding, a shear key has been provided. The question is, since the foundation is on the edge of the embankment and the only soil retained by the...
