I am designing an abutment on footing and the client is requesting that we use dowels to tie in to rock. I have been looking for an example with rebar anchored into rock but I can not find any thing. I was hoping that you can refer me to an example or a reference that can help me in my...
yes you are correct I forgot to mention that that there are five ducts in this beam. only the middle duct was used to adjust the sweep on this beam.
Using LRFD the allowable concrete strength is 0.6 x fc' with fc' = 10 ksi, so I get an allowable concrete strength of 6 Ksi. Now the force applied...
the beam is an adjacent box beam 3' wide by 3.25' high and 104 ft long. the post-tensioning force applied is 21 Kips which reduced the sweep to 5/8". I want to demonstrate the following.
1.show that the force required to take out the excess deflection does not exceed the allowable cracking...
Thank you guys for your input.
KootK, yes this is for a bridge. Its actually the fascia beam of the bridge. I am researching on how I can tackle this problem using AASHTO LRFD. My starting point is a transverse post tensioning calculations that I did on one of my projects, very similar to...
A prestressed beam on one of my projects has a sweep of 1.5 inches which is more than the 1 inch tolerance. The prestressed beam fabricator is planning on reducing the sweep by post tensioning the beam. Has anyone used post tensioning to reduce sweep in prestressed beams using this technique...
