BIOGRAPHY 新建主栏目 Research Area 名称 High-performance steel structures (such as high strength steel structures and stainless steel structures) have received worldwide attention, owing to the fact that they can effectively promote the sustainable development of the construction industry and achieve the realization of the national carbon peaking and carbon neutrality goals. High-performance steel structures have been gradually applied in high-rise, long-span and heavily-loaded engineering applications. However, the distinct differences of mechanical properties between high-performance steels and mild steels, such as strength and ductility, will affect the bearing capacity, stability and seismic performance of the steel structures. To this end, we focus on improving the safety and economical design of high-performance steel structures, with the outcomes potentially promoting the development of internation design codes. 1. The stability design methods of 690~960 MPa high-strength steel structures were proposed, promoting the establishment of the unified stability design theory system of normal strength steel structures and high-strength steel structures. The cross-section and member behaviour of high-strength steel welded I-section components have been studied by comprehensive experimental and numerical modelling programme. The physical testing included material testing, membrane residual stress measurements, initial local and global geometric imperfection measurements and eccentrically/concentrically loaded tests. The numerical modelling programme was then performed, where finite element models were firstly developed and validated against the test results and then employed to perform parametric studies to generate further numerical data over a wide range of cross-section dimensions, member effective lengths and loading combinations. On the basis of the test and numerical data, more accurate design methods, based on the Continuous Strength Method (CSM), were proposed in terms of failure of local buckling, global buckling and local-global interactive buckling. Compared with the existing design rules, the proposed design methods can save the structural costs of steel structure applications by 20% ~ 30%. 2. The post-fire behaviour of high-strength steel structures was revealed, with the degradation mechanism of 690~960 MPa high strength steel structures clarified. The membrane residual stresses and mechanical properties of high-strength steel welded I-sections after exposure to elevated temperatures were studied through experiments and numerical studies. The experimental programme included heating and cooling of specimens as well as post-fire material testing, initial local geometric imperfection measurements and compression tests. Based on this, the influences of fire temperature on the peak tensile/compressive magnitudes of membrane residual stresses and the degradation laws of the post-fire stress-strain curves of high-strength steels were clarified, which could be used to accurately predict the post-fire residual bearing capacity of high strength steel members. 3. The stability design theories of stainless steel channel section and welded I-section members were established based on CSM. 4. Research into the structural performance of high strength steel built-up section members and 3D printed high-strength steel members is ONGOING!
