2.O DESCRiPTiON

2.1 General:

MetaiStudC「ete is a lighトgage steei connector strip used

to t「ansfe「 Shea「 st「esses in composite paneI systems

used as a「chitectu「al ciadding. The use of the st「ip is not

=mited to any seismic design catego「y. The composite

PaneIs consist of Iight-gage SteeI studs and a 「einfo「ced

COnC「ete facing o「 topping on one side of the studs, With

the MetaIStudC「ete metaI connector p「oviding a sheaト¶ow

COnneCtion between the steeI studs and the conc「ete. See

Figu「e l for a typieaI panel const「ucted with the

MetaiStudC 「ete comector strip.

2.2　Mate「iaIs:

2.2,1 Steei Studs: Whe「e the MetaIStudC「ete comecto「

iS uSed, Steei studs in　∞mPOSite paneis must be

recognized in a cu「「ent lCC-ES evaIuation report. PhysicaI

and section p「operties are found in the evaiuation report on

the steel stud. Minimum steel thickness and yieId st「ength

fo「 the studs must compiy with TabIe l ofthis 「eport.

2,2,2　MetaiStudCrete Connecto「: The MetaIStudCrete

COmectO「 t「anSfe「s shea「 st「esses between the concrete

faci=g and the lighトgage steel stud. The strip is fastened to

the web o「 flange of the stud and the ¶ange of the t「ack,

and the st「ip/flange is then embedded into the concrete

facing. The st「ip is fab「icated f「om No. 18　gage

[0.047 inch (1.19 mm)] steel, COmPIying with ASTM A653SS, Grade 33. The gaIvanized coating compiies with

ASTM A924. See Figure　2　fo「 dimensions of the

MetaIStudC「ete connecto「.

2・2・3　Concrete: The conc「ete facing is no「ma」Weight

COnC「ete COmPIying with the p「ovisions of IBC Chapter 19

O「 IRC Section R402.2, aS aPP=cable. The minimum

COmPreSSive strength, f6, muSt be 2,500 psi (17.2 MPa) at

28 days.

2・2"4　Steei Reinfo「cement: Conc「ete panels must be

「einforced in a∞O「dance with the st「ucturaI design, a=d the

Steel 「einfo「∞ment muSt COmPly with the iBC.

2,2.5　Screws: The MetaIStudC「ete connector must be

atfached to the stud using galvanjzed, Seif-d輔ng, SeIf-

tapping sheet metal screws confo「ming to SAE J78 and

AiSi CF 92-1. Table l shows caiculated a=owable shea「

Values for various sc「ew sizes fo「 the stud st「ip attached to

Va「IOuS thicknesses of stud. The vaiues have been

calculated using a factor of safety of 3.O and the gene「al

fastene「 formulas given in the cu「rent edition of the AISi

COld formed steei design manual, “North Ame「ican

Specification for the Design of CoId Formed Steel

Structu「ai Membe「s・’’Screw manufactu「er,s design vaiues

must be deveIoped using the test provisions of the

SPeCification. The design engineer must calcuiate the

Shear, Pullout and tension 「equi「ements and seIect a screw

Which has su簡cjent capacity.

2.3　Design:

The paneIs a「e designed using the accepted enginee「i=g

P「inciples of transfo「med section p「operties and a=owable

StreSS design. The design mus=nciude conslde「ation of

MetaIStudCrete ∞nnectO「 and the steeI stud, and the

Shea「 flow capacity, q, Of the connection between the

MetalStudC「ete comecto「 and the ∞nCrete. The design

must aIso consider the strength and serviceabi=ty of the

CO nC「ete.
