RE: Brittle and Ductile steel elements

[Subject Prev][Subject Next][Thread Prev][Thread Next]
    No. All ASTM F1554 anchor rods are ductile and the highest Fu is 125 ksi for F1554, Gr 105. Look under the definitions in the front of Appendix D for the requirements for ductile vs brittle. The requirements relate to elongation and reduction in area under tension loading. PCA's commentary on 318-05 Appendix D has a chart with these properties listed for some common steel types. If you are just beginning to work with Appendix D, I would highly recommend PCA's commentary on the code. It has many helpful resources.

Hello All
In regard to anchors embedded in concrete ACI 318 App D regarding Brittle and Ductile steel elements
Is it correct to assume if the Fu of the bolt is 65ksi or less then it is Ductile and over 65ksi is Brittle ??
