Steel Quality

Williams 1&#; through 1-3/4&#; 150 KSI bars are widely available as cold-stressed and stress relieved in strict compliance with ASTM A722 and AASHTO M275 Highway Specifications. While the 2-1/4&#; through 3&#; 150 KSI bars are exclusively available as alloy steel that is quenched and tempered to meet the prescribed tensile properties of ASTM A722, all sizes are available and occasionally supplied using this process.

Thorough inspection and traceability are carried out during all phases of manufacturing to assure the highest standards of quality.

Properties

Williams 150 KSI bars are manufactured in 7 diameters from 1&#; (26 mm) through 3&#; (75 mm).  All diameters are available in continuous lengths up to 50&#; (15.2 m).

Williams 150 KSI bars are high in strength yet ductile enough to exceed the specified elongation and reduction of area requirements.  Selected heats can also pass the 135° supplemental bend test when required.  Testing has shown Williams 150 KSI All-Thread-Bars to meet or exceed post tensioning bar and rock anchoring criteria as set by the Post Tensioning Institute including dynamic test requirements beyond 500,000 cycles of loading.

Tensile Strength & Working Loads

Per PTI recommendations for anchoring, anchors should be designed so that the design load is not more than 60% of the specified minimum tensile strength of the prestressing steel.  The lock-off load should not exceed 70% of the specified minimum tensile strength of the prestressing steel.  The maximum test load should not exceed 80% of the specified minimum tensile strength of the prestressing steel.  The maximum test load and the maximum factored design load must not exceed the yield strength of ANY steel element.

Threads

All-Thread-Bars are cold rolled threaded to close tolerances under continuous monitoring procedures for quality control.  Threads for Williams 150 KSI bar are specially designed with a rugged thread pitch wide enough to be fast under job site conditions and easy to assemble.  They also have a smooth, wide, concentric, surface suitable for torque tensioning.  This combination offers tremendous installation savings over inefficient, hot rolled, non-concentric thread forms.  Threads are        standard left-hand for diameters up to 1-3/8&#; and right-hand for diameters over 1-3/4&#;, with any direction available on special request.

Williams All-Thread-Bars are threaded around the full circumference enabling the load transfer from the bar to the fasteners to occur efficiently without eccentric point loading.  Williams fasteners easily meet the allowable load transfer limitations set forth by the Post Tensioning Institute.  Williams 150 KSI All-Thread-Bars and fasteners are machined to tight tolerances for superior performance and mechanical lock.  Precision machining greatly reduces concern of fastener loosening or detensioning.  Williams 150 KSI  bars exceed the deformation requirements of ASTM A722.  Williams special thread deformation pattern projects ultra high relative rib area, much greater than conventional rebar.  This provides for superior bond performance in grout or concrete.

Cutting (No Welding)

Williams 150 KSI All-Thread-Bar should not be subjected to the heat of a torch, welding or used as a ground.  Field cutting should be done with an abrasive wheel or band saw.

Stress Relaxation

Currently ASTM A722 does not include prescribed maximum relaxation thresholds.  However, Williams can provide 150 KSI bars that meet project specific relaxation values.  Consult your WFEC rep for more information.

Shear

ACI 318-14, Section 17.5.1.2 indicates that the nominal shear strength of an anchor not exceed 0.60 x area of steel x the ultimate strength of the steel.  Designers should utilize appropriate resistance factors for shear based on the condition of use.

150 KSI All-Thread-Bar Accessories

All Couplings and Hex/Collar Nuts exceed 100% of the bar&#;s published ultimate strength and couplings will meet ACI 318 Section 25.5.7.1 for mechanical rebar connections.
