N°206. 1991. Fastenings to Reinforced Concrete and Masonry Structures. Vol. 1

(1991; ISBN 978-2-88394-011-6 and -012-3; 562 pages; for printed revised hardbound edition see N° 216).

Modern fasten ing technique is increasingly applied for transfering concentrated loads into concrete and masonry structures. Used are cast-in­-place systems, which are placed in the formwork before casting the concrete and post- instal led systems, which are installed in hardened structural concrete or masonry. 

The load is transferred into the base material by mechanical interlock, friction, bond or a combination of these mechanisms. In genera! independent of the load transfer mechanism, fastenings rely on the concrete tensile capacity. 

In spite of the tact that a large number of fastening assemblies are installed every day, the knowledge in the engineering profession about their behavior is generally very limited . Furthermore, there exists no generally accepted design method. 

In order to improve the situation, the Task Group Vl/5 " Fastenings to reinforced concrete and masonry structures" has been formed by CEB with the aim: 

- to compile and compare the available research results concerning the behavior of fastening systems; 

- to propose a consistent approach based on current empirical and theoretical models tor the design of fastenings; 

- to develop design methods that account tor the effects of fastenings and the loads they carry on the behavior of the structures to which they are attached.
