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...

Strengthening of reinforced concrete (RC) columns is needed when the actual load-carrying capacity does not reach required level due to either structural deterioration or increasing acting loads. This experimental study aims evaluate strengthening effect on eccentrically-compressed RC using Carbon fiber polymer (CFRP) sheets, that confine around column cross-section. Three specimens with same g...

To investigate the mechanical properties of eccentrically loaded steel reinforced recycled concrete filled square tube columns, 14 specimens columns were designed and tested. The failure modes, load-displacement curves, bearing capacity deformation obtained analyzed in detail. In addition, numerical model considering unfavorable effects coarse aggregate (RCA) restraint effect also established b...

Electromyographic (EMG) amplitude and mechanical tension are directly related during isometric contraction. Maximal voluntary isometric contractions are typically elicited through two different procedures; resisting a load, which is eccentric in nature, and contracting against an immovable object, which is concentric in nature. A wealth of literature exists indicating that EMG amplitude during ...
