Corrugated web girders represent a new structural system emerged in the past two decades. The girder’s flanges provide the flexural strength of the girder with no contribution from the corrugated web which provides the girder’s shear capacity. Failure of the web occurs by steel yielding, web buckling or interactively between them. Lateral torsion and local flange buckling of corrugated web gird...

This paper presents the difference in behavior between hollow-core fiber reinforced polymer-concrete-steel (HC-FCS) columns and conventional reinforced concrete (RC) columns under vehicle collision in terms of dynamic and static forces. The HC-FCS column consisted of an outer FRP tube, an inner steel tube, and a concrete shell sandwiched between the two tubes. The steel tube was hollow inside a...

To study the cold-forming effect on yield strength distribution of cold-formed thick-walled steel, material tensile tests and axial compression were conducted steel-lipped channels. undertake tests, five types lipped channel sections with varied thicknesses nominal strengths selected. The test samples taken from web, flange, curled edge, corner sections, respectively. Next, a corresponding mode...

Research reported in this paper was carried to study the water permeability of steel fibre reinforced concrete (SFRC) with varied aspect ratios of steel fibres. Corrugated steel fibres were used in the investigation at constant fibre content of 0.5%. Relationship of water permeability with compressive strength and split tensile strengths has been presented. The water permeability was observed t...

The experimental study presented in this paper aimed to examine the performance of cold-formed steel built-up section beam-columns experiencing non-uniform bending. test program was performed on open and closed sections that were manufactured from grades G500 G550 zinc-coated sheets. specimens assembled by connecting two identical channels with discrete connectors along longitudinal direction. ...

Although there have been significant developments in the testing, simulation and design of stainless steel structural elements at room temperature, response members fire has received significantly less attention. In particular, full-scale tests on I-section members, which are becoming increasingly widely used engineering applications to meet growing load-carrying capacity demands, currently sca...

The behavior of two series corroded thin-walled concrete-filled steel tubes (CFSTs) was investigated in this paper. One series, called the CT consists fourteen CFST specimens by NaCl solution, while other, AT six test pieces atmosphere. Outer surfaces were scanned using a 3D scanner machine, and complete surface profile each specimen obtained for corrosion evaluation different methods study. En...
