“…Different from carbon steel, stainless steel does not have a yielding plateau and exhibits a substantial strain hardening. Currently, most of the studies for stainless steel connections still focus on the behaviour of bolts in shear or tension [40], plates in bearing [41][42][43][44], T-stubs [29] and tubes in bearing ( [45,46]). Recently, Elflah et al [47,48] conducted an experimental and numerical studies on stainless steel I beam-to-H column connections [47] and stainless steel I beam-to-tubular columns [48].…”

“…High strength steels are becoming increasingly attractive in a range of structural applications. Although several experimental investigations [3][4][5][6] were carried out on concrete-filled tubular chords under concentrated bearing loads, research into concrete-filled high strength steel tubular joints has been rather limited.…”

The structural performance and design of concrete-filled high strength steel tubular X-joints subjected to compression are investigated. A numerical investigation on the behaviour of concrete-filled high strength steel tubular chord members under concentrated bearing load has been performed. The high strength steel tubes had nominal yield stresses of 700 and 900 MPa. The infilled concrete had nominal concrete cylinder strengths of 35 and 100 MPa. In order to avoid the failure of brace members and reveal the true capacity of the X-joints, steel bearing plates were used to simulate the brace members. A finite element model was developed and validated against test results. Furthermore, a parametric study comprised 156 finite element analyses was carried out. The strengths of the concrete-filled high strength steel square and rectangular hollow section X-joints obtained from the parametric study together with available data in the literature were compared with the nominal strengths calculated from the CIDECT Design Guide. It is shown that the CIDECT design predictions exhibit significant scatter and could be unconservative for the concrete-filled tubular joints with chord sidewall slenderness ratio beyond 40 in this study. Hence, new design rules are proposed for concrete-filled high strength steel tubular X-joints subjected to compression. It is shown that the proposed design rules are able to provide reasonably good predictions.

SUMMARY The use of high‐performance materials (HPMs) such as high‐strength concrete (HSC) and high‐strength steel (HSS) is becoming more popular in the construction of beams and columns of tall buildings. These HPMs not only increase the stiffness and decrease the strength‐to‐weight ratio, but also provide a more sustainable construction method by minimising the construction materials needed. However, HSC and HSS are more brittle than normal‐strength concrete and steel, respectively. Therefore, it will adversely affect the deformability of concrete beams. To evaluate the pros and cons of adopting HPM in beam design, the author will investigate the flexural strength and deformability of concrete beams made of HPMs. The deformability in this study is expressed in normalised rotation capacity and investigated by a parametric study using nonlinear moment–curvature analysis taking into account the degree of reinforcement, confining pressure, concrete and steel yield strength. From the results, it is evident that the deformability of concrete beams increases as the degree of reinforcement decreases or confining pressure increases. However, the effects of concrete and steel yield strength depend on other factors. For practical design purpose, charts and formulas are produced for designing high‐performance concrete beams to meet with specified flexural strength and deformability requirement.
