RVL wire rope loops manufactured by R-Group Finland Oy are steel parts consisting of a high
strength steel wire and a steel box. RVL wire rope loops are installed to concrete elements before
casting.
When the joint between concrete wall elements is loaded, the longitudinal shear force in the joint
is divided to an angled compression component and a horizontal pull component at the indented
joint. RVL wire rope loop transfers the shear forces acting in the joint between concrete wall ele-
ments by the pull component of the wire rope and the compression component formed by the steel
boxes and the joint

The steel box and the wire rope are zinc coated. Zinced products are
passivated with min. 1 month of storage.
The steel is box is mechanically cut and bent to shape. The open wire rope is installed to the
steel box and attached by the compression sleeve to form a loop. The wire rope is bent in to
the steel box and the open part of the steel box is closed by tape to protect from casting concrete.
Product package is equipped with a R-Steel –sticker, which contains the following information:
product type, product name, quantity, ISO9001 and ISO14001 quality and environment system
markings, FI marking and product picture.
Products are delivered in cardboard boxes on a truck palette. Cardboard boxes are marked with
FI logo, numbers of the ISO-certificates and the product type and name.
Quality control of the wire rope loops is done according to the requirements of the Finnish
Code of Building Regulations and the instructions according to the quality and environment
system of the R-Group Finland Oy (ISO9001 and ISO 14001). R-Group Finland Oy has a quality
control contract with Inspecta Sertifiointi Oy.

4. Resistances According to ACI
Design value of resistance VRd for one pair (one wire rope loop on each side of the joint) is
presented in table 2. The minimum concrete strength in the joint (element/joint concrete) is
C25/30 (cylinder strength 25 MPa, cube strength 30 MPa). Distance between wire rope loop pairs
must be according to section 6.1.1.

The longitudinal shear capacities of the RVL wire rope loops are calculated according to
Building Code Requirements for Structural Concrete (ACI 318M-08).
Capacities are calculated for static loads. The calculations do not take into account cracks or
deformations in the joint.
