Design of Precast Prestressed Beams according to Eurocode

Design of Precast Prestressed Beams according to Eurocode

(OP)
Hi,
Can anyone provide me with a resource or point me in the direction of one for the design of precast prestressed beams according to Eurocode? I have been looking all over the internet but so far have not found anything of note.

RE: Design of Precast Prestressed Beams according to Eurocode

They are there because the Europeans have been building with precast and prestressed for years before the U.S. Sometimes the terminology makes the searches difficult. Most of the information is from German and Eastern Europe sources sine that is where the systems were developed and the Eurocodes are based on that.

I know, I have all these codes, but I can't find some things in them. E.g., can you tell me the maximum allowable tensile stress in concrete at service?

RE: Design of Precast Prestressed Beams according to Eurocode

I have little experience with the Eurocode 2 but I don't think it specifies a tensile limit for concrete in service (EN1992-1-1 2004: 7.2). Instead they specify crack control measures (7.3). They don't distinguish between full and partial-prestressing.

Hi saadpervez1,

In Singapore just started to use EC2. First of all I am not experienced enough to tell someone what to do but I know that there is no limit on tensile stress (class 1, 2, 3 like in BS) unless you are referring TR43 and no separate chapter for prestressed concrete just additional notes for prestressed at each RC section. So it is just RC design with prestressed implications which is very logical unlike BS (making people confused with the classes :)). You just need to decide whether the section is cracked or uncracked or decompression.

And for your prestressed beam design, I think you need to go through EC2 and I believe that the basis engineering theories will be the same no matter which code you are referring to. Thanks to people who told me that. BTW I did ask a post like yours in this forum.

Part of engineering is paying for the appropriate codes.

Or downloading the free copy, when available.

This appears to be a legitimate site with free downloads of all Eurocodes, structural codes of many other countries (but not USA or Australia), and many other related documents.

Thank You all.

Designed the girder on ACI codes. And justified the design using provisions of Eurocodes. Let's hope it is approved.

Cheers.
