Abstract Traditional hollow concrete filled steel tube components are mainly used in the transformer power structure. In order to improve mechanical properties and application scope of components, a new type reinforcement high-strength combination structure is proposed. Given that construction system frequently an eccentric stress condition throughout structural system, finite element analysis ...

Continuous casting is used to mass produce basic metals into long, semi-finished shapes with constant cross section, which are later processed into over 800 million tons of steel, 20 million tons of aluminum, and 1 million tons of copper, nickel, and other metal products in the world each year. Cross-sections can be rectangular, for later rolling into plate or sheet, square for long products, c...

Cold-formed steel (CFS) unlipped channel sections are commonly used as bearers in floor systems while rectangular hollow (RHS) joists. The transverse loads from the joists do not pass through shear centre of due to different joist bearer and column connections. Hence, subjected torsion addition concentrated bending. This study investigated effects two (bolted/welded) connections, (cap plate/ang...

To date, theoretical studies concerning the Carbon Fiber Reinforced Polymer (CFRP) strengthening of RC beams with openings have been rather limited. In addition, various numerical analyses presented so far have effectively simulated the behaviour of solid beam strengthened by FRP material. In this paper, a two dimensional nonlinear finite element analysis is presented to validate against the la...

Although there are many simulations of residual stresses in quenched steel components there is little validation of these predictions particularly when the components are large. This is not surprising bearing in mind that the application of the through thickness measurement techniques (mechanical strain relief techniques) are problematic when the components exhibit high levels of residual stres...

The assessment of response of composite seismic force resisting systems requires accurate nonlinear formulations for the composite members. In this work, reporting the first phase of a NEES project, a three-dimensional distributed plasticity formulation is presented for both circular and rectangular composite concrete-filled steel tubes (CFTs) that includes new constitutive models for the concr...

The analysis and design of structures sensitive to second order effects require the consideration initial imperfections. Scaffold structures, due their low stiffness, are very effects. accuracy these relies in part on estimation imperfections affecting structure. In 1960s, C.E.C.M., European Convention Steel Construction, carried out a series experimental tests determine degree each type cross-...

Concrete-filled composite elements have recently gained popularity as beams and columns all over the world. They advantages similar to reinforced concrete elements, such moulding process lack of maintenance filled concrete, well hollow steel enhancing compressive strength bending capacity by using smaller sections. In this paper, buckling behaviour thin-walled with circular cross-section differ...
