| Abstract: | Steel plates for building structures have been used in many major domestic projects. There are already design values for Q345GJ steel in GB 50017—2017 ‘Standards for design of steel structures’. The design values of high-strength steel plate for building structures need to be studied urgently. In this paper, the material properties of Q460GJ steel with the thickness t≤50mm were statistically analyzed, and the statistical parameters of its uncertainty of the first set thickness (t≤16mm) and the second set thickness (16mm
