Steel thin-walled beams have been widely used in civil engineering as purlins, ceiling beams or wall substructure beams. There are often planar members such as trapezoidal sheeting or sandwich panels used as roof or wall cladding fastened to the steel beams. The planar members also serve as stabilization of thin-walled beams against buckling due to loss of stability. This paper focuses on probl...

Concrete columns confined with high-strength fiber reinforced polymer (FRP) composites can enhance the strength as well as the ductility of such structures. In recent years, the use of FRP composites to repair and strengthen existing reinforced concrete (RC) structures has been widely used. When the columns of existing RC structures are wrapped with FRP composites, the core concrete of such col...

In recent years, rehabilitation has been the subject of extensive research due to increased spending on building work and repair of built works. In all cases, it is absolutely essential to carry out methods of strengthening or repair of structural elements, and that following an inspection analysis and methodology of a correct diagnosis. The reinforced concrete columns are important elements in...

Corrugated web beams made of cold-formed steel components represent an economical solution for structures, offering high flexural capacity and deformation rigidity. For conventional corrugated beams, thick plates the flanges thin sinusoidal sheets web, elements can be joined by standard bolted end-plate connections. In case thin-walled only, additional are required to accommodate shape position...

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....
