Punching Shear Reinforcement: Technical Support Services
Ancon Shearfix is used within a concrete slab to provide additional reinforcement around column heads, protecting the slab from the effects of punching shear.
Shearfix offers many advantages over the use of loose shear links, which can be time-consuming to both design and install. A Shearfix system comprises double-headed steel studs. To simplify installation, and ensure alignment and accurate positioning within the slab, the studs are supplied welded to flat rails.
Ancon distributes free design software and provides free design assistance. Ancon’s Technical Services Team has created a faxback form for engineers to effectively summarise the critical details of their project and to request assistance with a Shearfix design.
Now available in lengths of 325mm and 350mm, the Ancon ST1 wall tie range has been extended to suit high-rise masonry buildings with insulated cavities up to 225mm wide.
When forming a cross brace using tie bars, the new Ancon Cross Coupler offers a streamlined alternative to an anchor disc.
