for steel and timber BESISTA® 540
Please note: The diameter of pins subject to compression loads are larger, see MENU “Technical data” page 5 or ETA Annex 7.
Under European Technical Approval ETA-08/0038, the rod anchors can also be used to connect compression rods. The limit compressive force of the rod anchors used with compression rods shall at least match the limit tensile force NR,d tension rod of the corresponding tension rods – see also MENU “Type stress analysis” Annex 8. Normally, however, buckling check on the compression rods will be decisive.
The limit compressive forces shall comply with the limit tensile forces for rods made of S540N (type 1 and 3) or S355 (type 2). For the compression rods themselves, the buckling check shall be performed in each individual case. With regard to the compression rod connections type 2 made of S355 (machined components), the limit compressive forces depend on the product thicknesses of the products of the starting material.
All types are individually manufactured by BESISTA International GmbH in accordance with the client‘s structural check on load-carrying capacity. Welding of the compression rod connections to the steel tubes is carried out by the others.
