Chemical CompositionDesignationOther Mechanical PropertiesHow A36 Is MadeCommon Uses of A36A36 is a low carbon steel.Low carbon steels are classified by having less than 0.3% carbon by weight.This allows A36 steel to be easily machined,welded,and formed,making it extremely useful as a general-purpose steel.The low carbon also prevents heat treatment from having much of an effect on A36 steel.A36 steel usually has small amounts of other alloying elements as well,including manganese,sulfur,phosphorus,and silicon.These alloying elements are added to give A36 steel its desiSee more on metalsupermarketsLRFD Example 4 2-Span Precast Prestressed I-GirderTensile Strength fpu = 270 ksi Yield Strength fpy = 243 ksi Modulus Elasticity Ep = 28500 ksi Concrete The final and release concrete strengths are specified below Precast I-Girder Deck fc = 5.0 ksi fc = 4.5 ksi fci = 4.7 ksi Unit weight for normal weight concreteI would be alright using the tested yield with a qualifier.

strength,a stress at the point of unloading that corresponds to a strain of 0.002 is used.This method of determining the yield strength is called the 0.2% offset method.The two properties usually needed for steel design are F u and F y regardless of the shape of the stress-strain curve and regardless of how F y was obtained.F u F y E Monthly Supervisors Meetingassures that mild compression steel with f y 60.0 ksi will yield.For yield strengths above 60.0 ksi,the yield strain is close to or exceeds 0.003,so the compression steel may not yield.It is conservative to ignore the compression steel when calculating flexural resistance.In cases whereRole of Yield-to-Tensile Strength Ratio in the Design of A913 Grade 65 steel mechanical properties requirements are yield strength 450 MPa (65 ksi),and tensile strength of 550 MPa,resulting in a Fy/F u ratio of 0.82.Steels for application in bridges are covered in ASTM A709/709M.High-performance steels (HPS) are the newest additions to the family of bridge steels.The HPS-70W [485W],which has

Over The past several years,the concrete industry has made high strength concrete available for the construction of high-rise buildings.However,the reinforcing steel that is used has stayed at Grade 60 ksi.The use of high strength steel with high strength concrete simply makes technological sense,enabling engineers to design complex structures safer.STRUCTURAL STAINLESS STEEL DESIGN TABLESTwo strength levels are covered 30 ksi which corresponds to austenitic stainless steels and 65 ksi which corresponds to duplex stainless steels.The initial modulus of elasticity was taken as 28,000 ksi (193,000 MPa) for the austenitic stainless steels and 29,000 ksi (200,000 MPa) for the duplex stainless steels (Table 2-9 of DG27).STRUCTURE magazine Steel Deck FAQs80 ksi steel and other high-strength or full-hard steel coils typically have lower ductility than lower strength steels.The American Iron and Steel Institute (AISI) S100 specification limits the maximum permissible design yield stress to 60 ksi for these lower ductility steels (with potential exceptions for the flexural yielding limit state).

A steel bar of yield strength 60 ksi,ultimate tensile strength 80 ksi,and endurance limit 40 ksi is subjected to a steady torsional shear stress of 15 ksi and an alternating bending stress from 0 to 25 ksi.Some results are removed in response to a notice of local law requirement.For more information,please see here.12345NextSteel - Memphistensile strength of weld metal,the lower-bound strength of welds shall be taken as indicated in AWS D1.1 .For construction pre-dating 1970,use of a nominal ultimate tensile strength of 60 ksi shall be permitted.5.3.2.2 Component Properties The following properties of components and their connections shall be obtained for the structure 1.
