Silverstone Precast Inc.Hollow Core PLank Technical Guide | 1
IntroductionThe purpose of this technical guide is to provide assistance in select-ing and detailing precast hollow core plank manufactured by Silverstone Precast Inc.. Additional information and standard specifications are available at silverstoneprecast.ca
The load tables presented herein are intended as a guide only. Final design is determined by our engineering department based on infor-mation presented in the final plans and specifications. To ensure the optimum selection for your application, please contact us for assistance.
Although care has been taken to provide the most accurate data possible, Silverstone Precast Inc. does not assume responsibility for errors and omissions.
The Manufacturing ProcessElematic® is a machine extruded, precast, prestressed hollow core plank.
Standard widths are 48 inches and thickness of 8,10 and 12 inches. High strength prestressing strands are cast into the planks at the spacing and location required for the given span, loading and fire cover conditions. The planks are cut to length for each project using a diamond-blade saw. After the planks are cut, they are removed from the casting beds and placed into storage.
All Elematic® materials equal or exceed the requirements of applicable ASTM specifications. The concrete mix is designed to have release strength of 3,000 psi or 3,500 psi, and a 28-day compressive strength of 5,000 psi. The prestressing strands are uncoated, seven wire, low relaxation with a minimum ultimate strength of 270 ksi.
Load Table Design CriteriaThe tables herein list allowable live loads in pounds per square foot
for uniformly distributed loading. Non-uniform loading conditions resulting from point loads, line loads, openings and cantilevers require special design consideration.
The allowable load is usually governed by the ultimate capacity of the section. As a design aid, the ultimate moment capacities in governing criterion for short spans may be the horizontal shear stress between the plank and the topping.
Allowable live loads for long-span, heavily reinforced sections are limited to loads that result in a bottom-tension stress equal to the crack-ing stress. Loads beyond this limit may result in deflections that exceed the allowable value set forth in the ACI code.
The load tables are based on a plank concrete strength of 5,000 psi. Tables for topped sections are based on a topping strength of 3,500 psi and minimum thickness of 2 inches.
Maximum spans and loads shown are not absolutes. Longer spans or heavier loads may be achieved under certain conditions or different criteria than assumed in the tables. Contact us if you need assistance.
Plank Design ConsiderationsThe following items will affect the selection of appropriate plank
sizes and should be carefully reviewed by the Architect/Engineer while developing the plans and specifications for a project:
Fire Rating
• The fire rating requirement should be clearly specified in thecontract documents.
Loading Conditions
• Specify all uniform loading requirements on structural plans.• Identify line and point loads resulting from bearing walls, masonry
walls, face brick, columns, mechanical equipment, etc.• Identify diaphragm forces and lateral loads resulting from wind or
earth pressures.• Review roof plans for vertical protrusions such as parapets, pent-
houses and adjacent buildings that could require designing forsnow drift loads.
• Plank supporting stairs require special loading considerations.• Large openings or closely spaced groups of smaller openings will
reduce the plank load carrying capacity.
Topping
• Specify whether or not concrete topping is to be composite.Composite action requires the topping to be bonded to the topsurface of the plank. Topping separated by a vapor barrier orinsulation is non-composite and must be considered asuperimposed load.
• Large cambers resulting from long spans and/or heavy loads willaffect the quantity of topping, assuming a level floor is required.Two inches of composite topping at mid span is minimal, andadditional thickness at the ends of the plank may be required tomaintain level floor elevations.
Camber
• Camber is inherent in all prestressed products. It is the result of theeccentric prestress force required to resist design loads, andcannot be designed in, out, or to an exact number. The amount ofcamber will depend upon the span, design loads and thickness ofplank. Planks stored in the yard for more than 6 weeks, usually dueto construction schedule changes, will experience more cambergrowth.
• Adjacent plank of dissimilar length, strand pattern or with openingswill have inherent camber differences.

Fire RatingFire rating specifications are as important as all other design parameters.
Plank rating requirements are determined by the Architect or Engineer of Record, who is also responsible for establishing the fire rating criteria for the total project.
Three methods generally for determining hollowcore plank fire-resistive ratings are:
1. 2006 International Building Code2. Rational analysis as defined by PCI MNL 124, “Design for Fire
Resistance of Precast Concrete”3. Underwriters Laboratories Fire Resistive Ratings
International Building Code “IBC” Fire RatingThe IBC code prescribes fire ratings to any hollowcore plank section.
Since 2000, the IBC code has replaced the BOCA, SBC and UBC model codes in many states. The two criteria that are measured to determine the fire rating are:
1. Equivalent concrete thickness – 4.6" inches is required for 2 hrs2. Bottom strand cover – ¾" cover is required for 2 hrs (restrained
condition)
Underwriters Laboratories Fire Resistive RatingsPrior to codes including prescriptive fire-endurance rating methods,
fire tests provided the primary source of ratings classifications. While some plank sections were fire tested, others can be evaluated by UL to qualify for existing UL numbers.
The table below lists the UL ratings available with Elematic® plank. Note that these ratings are dependent upon whether or not the ends of the planks are restrained. Determination of the restraint must be made by the Architect or the Engineer of Record, as it is primarily a function of the support structure.
Fire Ratings by Rational AnalysisPCI MNL 124 defines the “rational analysis” method for determining
the fire rating of precast, prestressed members. It is useful when a fire rating cannot be obtained by either of the two previous methods. Actual practice has shown that this method is very conservative and that the span of the hollowcore plank will have to be reduced (approx. 10% to 20%) to achieve the same fire rating from both IBC and UL.
In using this method, the reduced strength of the prestressed strands at elevated temperatures is determined and the resulting moment capacities are compared to that required for service loads. Strand

temperatures are based on the amount of concrete cover and the standard fire exposure as defined by the time-temperature relationship specified in ASTM E119. Fire ratings will also be improved if the plank assembly is restrained against thermal expansion. It should be noted that the only universally accepted definition of full restraint is an interior bay of a multi-bay building.
Sound RatingsThe following tables contain values for the Sound Transmission Class
(STC) and the Impact Insulations Class (IIC) of various floor systems utilizing Elematic® hollowcore plank.
Sound Transmission Class (STC)The values for the
Sound Transmission Class were deter-mined by tests which were in accordance with ASTM E90. The STC is a measure (in decibels) of the ease at which air-borne sound is transmit-ted through a floor system. The larger the value of the STC for a given system, the greater the sound insulation.

Impact Insulation Class (IIC)
The values for the Impact Insulation Class (IIC) were determined by tests which were in accordance with ASTM ES492. The Impact Insulation Class is the resistance to impact noise transmission and is highly dependent on the floor surface and structural connection details. As with the STC, the higher IIC values are more desirable.

1 For precast concrete erected on a steel frame building, this tolerance takes precedence over tolerance on dimension “a”.
2 It may be necessary to feather the edges to ±1/4 in. to properly apply some roof membranes.
3 This is a setting tolerance and should not be confused with structural performance requirements set by the architect/engineer.
4 Untopped installation will require a larger tolerance here.
