Wide beams are one of the widely used structural elements in RC buildings due to many special features that characterize them. The main objective this research is investigate behavior wide shallow under effect eccentric loading acting along their cross sections. To achieve that, an experimental program consisted seven was conducted. All were loaded using two concentrated loads at middle third w...

All impact analyses performed so far for the composite plates, have treated central impacts. Furthermore, investigations on influences of the in-plane biaxial compression, tension, or tension-compression preloads on various responses of the low-velocity impact, especially the indentation, have not been performed so far. In the present research, a finite element formulation is presented for resp...

This paper summarizes the test results of an extensive research program sponsored by the US Transportation Research Board of the National Research Council to examine the behavior of high-strength concrete rectangular columns subjected to concentric and eccentric loading conditions. The variables considered in this investigation were concrete strength ranging from 7.9 ksi (55 MPa) to 16.5 ksi (1...

HYPOTHESIS Supraspinatus deficiency associated with total shoulder arthroplasty (TSA) provokes eccentric loading and may induce loosening of the glenoid component. A downward inclination of the glenoid component has been proposed to balance supraspinatus deficiency. METHODS This hypothesis was assessed by a numeric musculoskeletal model of the glenohumeral joint during active abduction. Three...

BACKGROUND Achilles tendinopathy is understood to be a failed healing response. Operative management is utilised following the failure of non-operative methods. CASE PRESENTATION We present a case of Achilles tendon rupture, sustained whilst isometrically loading the Achilles tendon during an eccentric loading exercise programme. CONCLUSION Bilateral surgical exploration and debridement had...

The purpose of this brief review is to examine our current knowledge of the neural control of eccentric contractions. The review focuses on three main issues. The first issue considers the ability of individuals to activate muscles maximally during eccentric contractions. Most studies indicate that, regardless of the experimental approach (surface EMG amplitude, twitch superimposition, and moto...
