DAfStb guideline - Strengthening of Concrete Structures with Adhesively Bonded Reinforcement - page 4

2.3 Work on the guideline
A subcommittee set up by the DAfStb began drafting the guideline as the research work
progressed. In accordance with DIN 820-1 [12], the groups involved (building
authorities, industry, research centres, official bodies, trade associations) were all
represented equally on the subcommittee. Within a year, a draft version had been
prepared. The draft, incorporating the results of research projects but also the expe-
riences of the members of the subcommittee, appeared in March 2011 as a paper for
discussion and was announced and presented to the industry in numerous publica-
tions [13 19]. Comments and objections could be filed by mid-September 2011. A

meeting to discuss and decide on objections was subsequently held. Following its
noti cation by the European Union, the finished guideline became available in the
summer of 2012. It can be purchased from Beuth Verlag. The DAfStb guideline [2] is
also available in English.

2.4 The structure and content of the guideline

2.4.1 General
The DAfStb guideline covering the strengthening of concrete members with adhesively
bonded reinforcement [1, 2] provides rules for design and detailing, the application of
national technical approvals for strengthening systems, execution and additional rules
for planning strengthening measures employing adhesively bonded reinforcement.
The guideline is divided into four parts. The first part covers the design and detailing of
strengthening measures using reinforcement bonded with adhesive. This part of the
guideline supplements DIN EN 1992-1-1 [20] with its associated National Annex [21] by
providing the additional requirements necessary for adhesively bonded reinforcement.
The second part of the guideline, together with the system approvals, describes the
products and systems used for strengthening measures with adhesively bonded reinforce-
ment. The third part covers the execution, and also contains advice on installing the
speci ed strengtheningmeasures. The fourth part of the guideline contains additional rules
for planning strengthening measures.

2.4.2 Design and detailing
As mentioned above, the first part of the DAfStb guideline supplements DIN EN 1992-1-1
[20] and its associated National Annex [21]. Its structure corresponds exactly to that of
DINEN1992-1-1, and there are additional provisions for materials, durability, ultimate limit
state, serviceability limit state, reinforcing principles and detailing.
Chapters 3, 5 and 7 of this topic describe the design and detailing provisions for different
strengthening measures and the background to these.

2.4.3 Products and systems

The second part of the DAfStb guideline covers the application of system approvals for
strengthening measures employing adhesively bonded reinforcement. Strengthening
must be carried out with an approved strengthening system using strengthening products
to DIN EN 1504-1 [22]. A strengthening system consists of various properly matched
