For　seismic　control　and　isolation　techniques,　low　yield　point　steels　are　among　the　most　reliable　and　ideal　energy-dissipating　materials.　Structures　under　earthquake　conditions　are　usually　subjected　to　cyclic　loads　with　large　strain　amplitudes,　where　excellent　low　cycle　fatigue　and　fracture　performance　under　repeated　loading　is　an　essential　requirement.　In　the　study　presented　in　this　paper,　comprehensive　and　systematic　investigation　was　conducted　on　the　low　cycle　fatigue　properties　and　fracture　behaviors　of　low　yield　point　steels　(LY100,　LY160,　and　LY225).　Axial　steel　coupons　were　tested　under　different　constant　strain　amplitudes　ranging　from　0.5%　to　6%　with　increments　of　0.5%.　Following　introduction　of　the　experimental　details,　observations　and　fatigue　life　are　reported.　Then,　based　on　the　experimental　data,　the　cyclic　hardening　behavior　and　the　cyclic　stress-strain　response　are　thoroughly　analyzed.　Finally,　with　the　aim　of　predicting　the　low　cycle　fatigue　life,　the　material　parameters　of　the　Coffin-Manson　relationship　and　Kuroda　model　are　determined　and　comparative　analyses　are　performed.　This　paper　may　provide　a　valuable　reference　for　engineering　applications　and　further　research　into　the　low　cycle　fatigue　performance　of　low　yield　point　steels.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
