Abstract Due to high bearing capacity and excellent seismic performance, the section steel reinforced concrete-filled rectangular tube has been widely applied in engineering. The application of stainless for outer can improve durability performance members. In this study, ABAQUS software was used perform nonlinear analysis on tubular columns, numerical model validated against experimental data....

The current paper focuses on numerical simulation peculiarities of offset welded rectangular hollow section joints. Understanding the modelling techniques can result in easier and faster above all correct outcomes from FEA for future use. steel joints under discussion are composed cold-formed regular sections where RHS brace members laterally shifted chord axis. Joints work monotonically increa...

This paper deals with the economic optimization of reinforced concrete road vaults and with the optimization of rectangular hollow section bridge piers typically used in road construction. It shows the efficiency of a heuristic optimization by the threshold accepting algorithm. The evaluation of solutions follows the Spanish Code for structural concrete. Design loads are in accordance to the na...

The behaviour of cold-formed normal- and high-strength steel columns with square rectangular hollow sections (SHSs RHSs) at elevated temperatures was investigated numerically in this paper. A finite element model developed validated against experimental results for the SHS RHS stub long tested ambient temperatures. Parametric studies were subsequently conduced on various cross-section slenderne...

This paper presents a detailed investigation into the flexural strength and behaviour of cold-formed steel oval hollow section beams. A series four-point bending tests were conducted as part experimental programme. Following this, total 12 tested beams simulated by non-linear finite element analysis. Upon validation newly developed numerical model, 36 results generated through parametric study ...

This paper is concerned with investigating of the plastic behaviour on gap K-joints truss girders, made from thin-walled rectangular hollow section members. An experimental study was carried out a full-scale girder under concentrated load two central nodes. A numerical analysis using ABAQUS in order to clearly see this type joint and make comparison experimentation. will it possible examine att...
