Appendix 9 to ASTM A370 specifically addresses tensile testing or reinforcing bars. The procedure below uses the MTS C64.206 test machine along with a pre-programmed test procedure. The pre-programmed test procedure should be adequate for most rebar testing. Should any alteration be needed, consult with FSEL staff beforehand. 1.1.
For rebar tensile testing, it is helpful to break down the tensile test into the separate stages of the test. This applies regardless of which test standard is being followed. The 5 basic regions are: Pretest Preload Elastic Region Yielding Plastic Region www.instron.com | Page 4 of 9 Elastic Region (before Yielding) The elastic region or .

Fig. 2 - Uncoiled rebar exhibiting slight bends over length .tensile testing steel concrete reinforcing bar (rebar) [4]. Recognizing the projected growth in new construction over the next decade and the increasing awareness of the nation’s deteriorating infrastructure, particularly roads and bridges, a decision was made to launch a program toTestResources manufactures and supplies universal test machines, tensile testers, dynamic testing machines, and much more. Call us today (800)430-6536. . ASTM A1034 test method covers the testing of mechanical splices for steel rebar re. ISO 1924 Paper and Board Tensile Strength. ISO 1924 specifies a method of measuring the tensile strength .
Steel reinforcing bars are designed to absorb the stress and weight of concrete structures such as bridges and buildings. ASTM A615 is a testing standard tha. of companion test bars sampled, as described in Section 3 above, shall be tested by the LOR in accordance with ASTM Standard A370 for the following: 5.1 Tensile strength, yield strength and elongation requirements (1 each). 5.2 Bend requirements (1 each). All reinforcing bars received by the laboratory for testing shall receive a distinguishing . Video 1: Tensile testing of annealed Cu sample (video and evolving nominal stress-strain plot) This page titled 5.5: Tensile Testing - Practical Basics is shared under a CC BY-NC-SA license and was authored, .Grade 60 rebar yield and tensile strength. Rebar is graded to show the amount of tensile strength it has in terms of pounds per square inch. Grade 60 rebar has a minimum yield strength of 60,000 PSI, which is equivalent to 415 MPa or 60 KSI. Grade 60 rebar has a minimum tensile strength of 90,000 PSI, which is equivalent to 620 MPa or 90 KSI.
rebar specimens prior to tensile testing. As a result, many test pieces may still have a slight bend or non-linearity over their length. Therefore, it is best if the load frame and grips are able to accommodate slightly bent specimens. Fig. 2 - Uncoiled rebar exhibiting slight bends over length .Rebar Testing Standards. Rebar reinforces concrete to support structures and buildings. Such an important function requires the rebar to meet a certain standard. . Tensile Test – To ensure that the rebar reaches the right tensile strength, a sample piece will be placed into a machine and put under stress until it breaks. This gives valuable .Method A is based on the increase in tensile stress during load application. In the linear elastic part of the tensile test, that is at the very beginning of the test, the rate of stress application must be between 1.15 and 11.5 MPa/sec (this corresponds to 10000 and 100000 psi/min).; However, it is clearly stated in ASTM E8 and ASTM E8M that these specifications and method do not .The hardness and tensile strength are inversely related to the ductility and weldability. Therefore, as the carbon content increases up to 0.85%, so does hardness and tensile strength. .

These accessories can be made compatible by TestResources to match test machines supplied by other .If the test specimen completes 80,000 cycles, continue testing the test specimen for ultimate tensile strength. 4.4 Ultimate Tensile Strength. 4.4.1 Apply a tensile stress at a rate between 10,000 and 100,000 psi/min. until the specimen factures. Record the maximum load, P, to the nearest 1 lbf. Note 62. Carbon Steel Rebar As the name represents, it is made up of carbon steel and is commonly known as Black Bar due to carbon colour. The main drawback of this rebar is that it corrodes, which adversely effect the concrete and structure. The tensile strength ratio coupled with the value makes black rebar one of the best choices.
