What is BS EN 846-7 - Specifications of shear ties and slip ties for load displacement about?
BS EN 846-7 is the seventh part of the multiple series document that is applicable to ancillary components for masonry.
BS EN 846-7 specifies the couplet method for determining the horizontal and vertical shear load resistance and load-deflection behavior of shear ties and slip ties embedded in mortar joints. The test is intended ties for connecting together two leaves of masonry forming a collar jointed wall or two walls at right angles. BS EN 846-7 also applies to ties used for connecting the edges of infill panel walls to frames that encircle them.
Note: The method measures the capacity of the tie alone and does not measure the contribution to the total shear resistance given by two masonry faces separated by a vertical mortar joint. This value should be obtained by wallette tests if required.
Who is BS EN 846-7 - Specifications of shear ties and slip ties for load displacement for?
BS EN 846-7 on shear load capacity and load-displacement characteristics of shear ties and slip ties is useful for:
- Builders
- Architects
- Contractors
- Manufacturers and suppliers of ancillary components
- Quality control inspectors
- Construction industries
- Testing laboratories of shear ties and slip ties
Why should you use BS EN 846-7 - Specifications of shear ties and slip ties for load displacement?
All of the masonry units for individual tests or for making the couplet specimens shall be taken from the same consignment. Masonry units shall be in an air-dried condition unless otherwise specified.
BS EN 846-7 assists you with the couplet method in which one end of the tie is embedded in a mortar joint, typical of the type for which the tie is specified, between a pair (couplet) of typical masonry units. The tie is then clamped at its free end and subjected to shear against reactive support for the couplet. Slip ties are also tested by the same method.
Overall, BS EN 846-7 helps you to determine shear load capacity and load-displacement characteristics of shear ties and slip ties that will help you to improve the masonry processes.
