Shear Ties No Longer An Issue By Using HRC 555 T-heads

HRC 555 headed shear ties can be used to speed up installation, eliminate congestion and improve structural performance! Headed shear reinforcement can be fabricated in many configurations to suit the demands of your application. HRC recommend the 180-Headed Stirrups (180 on top / HRC 555 Head on bottom) instead of Double-Headed stirrups for bar sizes up through #7, where the main objective is to speed up installation and/or eliminate the liability of 90 hooks. Headed shear reinforcement has proven particularly effective and practical in heavily reinforced foundations, slabs and walls by reducing congestion, improving anchorage and improving installation speed. An added advantage is that the concrete member will generally have higher shear capacity and/or better confinement under extreme loads. One of the biggest advantages to using headed shear reinforcement in lieu of hooked shear reinforcement is the reduction in “geometric presence” at the end of the bar. This helps the ironworkers greatly in terms of efficiency and safety while still providing adequate anchorage and development of the bar for the Designer. Heads allow for the bars to be easily fished or threaded through reinforcement curtains, mats or cages.
