چکیده
Fiber reinforced polymer (FRP) has been proved to be effective improve the structural strength and ductility for column structures. An experimental study was conducted investigate compressive performance of FRP confined glued-laminated timber (GLT) cross-laminated (CLT) columns. A total 60 specimens two dimensions in height using different types, thickness, laminate types were tested under cyclic axial compression loads. This focuses on capacity new composited structure. For this purpose, a loading protocol designed, including force-dependent pre-load an amplitude-increasing displacement-dependent load. The results showed that ultimate load considerably promoted by sheets. Wrapping sheets led average improvement 29% 24% CLT GLT specimens, respectively, compared initial stiffness unreinforced specimens. Using sheets, energy dissipation increased 358% 266%, respectively. In general, had higher rate while better potential sustained consumption if with sufficient

Behavior of Hollow-Core FRP-Concrete-Steel Columns Subjected To Cyclic Axial Compression
This report presents the results of an experimental study that was conducted to investigate the effects of key parameters on the compressive behavior of fiber reinforced polymer (FRP)concrete-steel double-skin tubular columns (FSDT). Hybrid FSDT columns have been introduced as a new form of hybrid columns. They consist of an outer tube made of FRP and inner tube made of steel, with sandwiched c...
متن کاملExperimental Study on Axial Compression Behavior of RC Columns Under Rapid Loadings
In this study, experimental study on six RC columns with different slenderness ratios under axial rapid loading was conducted to investigate the axial compression behaviour of RC columns considering the effect of strain rates. The failure pattern of the specimens and the relations of axial loading versus the axial deformation were described. From the test results, the specimens under static and...
متن کاملBehavior of FRP-Confined Reactive Powder Concrete Columns under Eccentric Loading
Fiber reinforced Polymers (FRP) have widely used for the purposes of enhances strength and ductility of concrete columns. Proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with FRP. In this paper, the influence of FRP thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reacti...
متن کاملAxial compression behaviour of retrofitted long timber columns
Spliced joints are used widely in retrofitting traditional timber structures, especially in heritage conservation applications where as much original material as possible needs to be retained. However, in practice this method is mainly applied based on experience, and there is a lack of understanding and quantification of the mechanical behaviour of retrofitted timber members. This paper presen...
متن کاملBehavior of FRP-Confined Concrete-Filled Steel Tube Columns
This paper presents the results of an experimental study into the behavior of concrete-filled steel tube columns confined by fiber-reinforced polymer (FRP). Eleven columns were tested to investigate the effects of the FRP layer number, the thickness of the steel tube and concrete strength on their load capacity and axial deformation capacity. The experimental results indicated that the FRP wrap...
