Abstract：

This　paper　presents　an　experimental　study　on　the　structural　behavior　of　low　yield　point　steel　(LYP225)　under　both　monotonic　and　cyclic　loading　under　the　triaxial　stress　states.　A　total　of　14　tensile　tests　on　four　types　of　specimens　with　various　initial　geometries　were　conducted　to　establish　monotonic　mechanical　properties　of　LYP225　steel　under　triaxial　stress　states,　and　10　ultra-low　cyclic　tests　(cycles　©　2025　Chinese　Society　of　Civil　Engineering.　All　rights　reserved.
