Designation:C129895(Reapproved 2013)Standard Guide forDesign and Construction of Brick Liners for IndustrialChimneys1This standard is issued under the fixed designation C1298;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 Thisguidecoversproceduresforthedesign,construction,and serviceability of brick liners for industrialchimneys.The structural design criteria are applicable tovertical masonry cantilever structures supported only at theirbase,either by a foundation,a concrete pedestal,or by somemeans from the outer concrete shell.Excluded from directconsideration are single-wythe,sectional brick linings that aresupported on a series of corbels cast in the outer chimney shell.1.2 The values stated in inch-pound units are to be regardedas the standard.The values given in parentheses are forinformation only.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C395 Specification for Chemical-Resistant Resin MortarsC466 Specification for Chemically Setting Silicate andSilica Chemical-Resistant MortarsC980 Specification for Industrial Chimney Lining BrickE447 Test Method for Compressive Strength of LaboratoryConstructed Masonry Prisms(Withdrawn 1997)3E111 Test Method for Youngs Modulus,Tangent Modulus,and Chord Modulus2.2 ACI Standard:30788 Practice for the Design and Construction of Cast-In-Place Reinforced Concrete Chimneys42.3 ASCE Standard:ASCE 7-88 Minimum Design Loads for Buildings and OtherStructures(Formerly ANSI A58.1)52.4 Other Standard:1991 Uniform Building Code,International Conference ofBuilding Code Officials,California63.Terminology3.1 Notations:a=brick dimension in radial direction(in.)b=brick dimension in tangential direction(in.)c=brick chamfer(in.)Ce=chimney deflection due to earthquake loads(in.)d=outside diameter of brick liner(in.)D=mean liner diameter at a given elevation(in.)Em=masonry modulus of elasticity as established by performing brick prismtest or by past experience,psifb=critical liner buckling stress,psifd=maximum vertical compressive stress due to dead load,psifde=maximum vertical compressive stress due to the combined effect ofearthquake and dead load,psifdw=maximum vertical compressive stress due to the combined effect ofwind and dead load,psifm=average ultimate masonry compressive strength established byperforming brick prism test or by past experience,psifv=maximum shear stress due to wind or earthquake,psiF.S.=factor of safetyh=total liner height(ft)he=height of liner above elevation being checked for buckling(ft)Le=liner deflection due to earthquake loads(in.)P=constructional out-of-plumbness of liner with respect to shell(in.)r=average mean radius of liner(ft)S=shell deflection due to sun effect(in.)T=liner deflection due to differential temperature effects(in.)t=wall thickness(in.)v=coefficient of variation in brick prism testsW=shell deflection due to design wind loads(in.)=coefficient of thermal expansion for brick liner(use 3.5 106unlessotherwise established)(in./in./F)1This guide is under the jurisdiction ofASTM Committee C15 on ManufacturedMasonry Units and is the direct responsibility of Subcommittee C15.05 on MasonryAssemblies.Current edition approved June 1,2013.Published June 2013.Originallyapproved in 1995.Last previous edition approved in 2007 as C1298 95(2007).DOI:10.1520/C1298-95R13.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.4Available from American Concrete Institute(ACI),P.O.Box 9094,FarmingtonHills,MI 48333-9094,http:/www.aci-int.org.5Available from American Society of Civil Engineers(ASCE),1801 AlexanderBell Dr.,Reston,VA 20191,http:/www.asce.org.6Available from International Code Council(ICC),5203 Leesburg Pike,Suite600,Falls Church,VA 22041-3401,http:/www.intlcode.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.Significance and Use4.1 History:4.1.1 For many years,brick liners have been used with anexcellent record of performance.For the most part,however,the design and construction of brick liners has been based onpast industry practice due to the lack of available informationand knowledge of the physical properties of the brick andmortar,the thermal and seismic behavior of brick liners,andmany relat
