PT Repair and strengthening

PT Repair and strengthening

PT Repair and strengthening

Hi everybody,
I am new to PT and my core competency is in the repair and strengthening of RCC structures using various techniques including but not limited to increase of area as well as external FRP bonding. I would like to know what are the courses, manuals, studies etc I need to develop a competency in repair and strengthening of PT structures. I do have good site experience but would like to develop good competency in design of PT (external PT) as well. Any suggestions / ideas are highly appreciated.

RE: PT Repair and strengthening

What location/area you based?

What type of PT is practiced/undertaken in that area - bonded (grouted) or UNbonded PT?

Are you dealing with buildings, or bridges, or both?

RE: PT Repair and strengthening

The powerpoint in this link from the Post Tensioning Institute of Australia is a great start.

Truncation of PT tendons is common when someone wants to cut a big hole in the slab, retrofitting a stair/lift shaft for example.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Un-bonded PT... *shudders*

RE: PT Repair and strengthening

Hi Ingenuity,
I'm based in middle east (in UAE to be precise) and here we do both kinds of PT i.e. bonded as well as unbonded. We are dealing with buildings and bridges both but as of now we are having like 90% projects of buildings. I am more interested in analysis and design of External PT. I have done some hand calculations for the effects of PT on a beam (elementary level problem). Want to delve into more advanced stuff including proper design of PT tendons for beams and slabs.

Thanks for the link and it seems quite useful to develop understanding related to truncation of tendons.

Thanks for the book recommendation but looks bit expensive to me as a starter.
