With the gradual application of composite materials to ships and offshore structures, structural strength composites that can replace steel should be explored. In this study, mechanical bearing failure modes a composite-to-metal joining structure connected by mechanically fastened joints were experimentally analyzed. The effects fiber tensile stress concentration on static structures investigat...

Reinforced concrete is the most commonly used material in construction industry. However, one disadvantage of reinforced that environmental factors cause materials to penetrate and steel bar corrosion. Rebar corrosion increases its volume significantly by approximately 3–6 times, which lowers concrete–rebar adhesion. This severely affects serviceability durability structures. The economic socia...

Steel structures are becoming more common in engineering construction as steel possesses excellent ductility, but members often vulnerable to buckling, especially under seismic or cyclic loading. Hollow structural sections (HSS) buckle locally loading due their thin walls and the need for rehabilitation strengthening is increasing. In present study, circular hollow section (CHS) have been stren...

Reinforced concrete (RC) beams may require flexural strengthening due to the corrosion of reinforcing bars or changes in design load. The near surface mounted (NSM) and externally bonded (EB) techniques, using either glass carbon fibre-reinforced polymer (GFRP CFRP) composites, are used for deficient RC beams. However, strengthened with both techniques susceptible debonding failure FRP composit...

This study investigates the effect of multi-walled carbon nanotubes (MWCNT) on high strain rate properties fiber reinforced polymer (CFRP) fabric impregnated with shear thickening fluids (STF). Three GFRP-STF and twelve GFRP-MWCNT/STF composite specimens were conducted using a split Hopkinson pressure bar (SHPB). Spherical silica nanoparticles (20.0 wt%) polyethylene glycol used to prepare sili...

Composite sandwich materials have yet to be widely adopted in the construction of naval vessels despite their excellent strength-to-weight ratio and low radar return. One barrier to their wider use is our limited understanding of their performance when subjected to air blast. This paper focuses on this problem and specifically the strength remaining after damage caused during an explosion. Carb...

Previous works have established the response and failure behaviour of hybrid (CFRP-GFRP) laminates when subjected to a wide range destabilising loads. However, date no focused on plates with cut-outs under shear loading quantified influence selective laminate shapes hybridisation their post-buckling response. Herein, plate collapse novel X-braced twill woven containing large circular cut-out (d...

a large number of bridges and buildings that are currently used, are made of slabs with opening. some of these buildings and bridges have been severely damaged because of natural disasters such as earthquake, storm and other effects such as materials fatigue and alkaline and corrosive agents. therefore, retrofitting and strengthening of these structures is essential and affordable. in this rese...

Many civil applications use square hollow sections (SHSs) as members in beam-column connections which can be vulnerable under cyclic loading. Cyclic loadings from earthquakes, wind, waves and currents affect onshore offshore infrastructure. In addition, these become structurally inadequate through incremental service loads, design/fabrication errors material property degradation over time. Due ...
