Both the flexural and shear strengths of reinforced concrete (RC) beams can be substantially enhanced using externally bonded fibre reinforced polymer (FRP) composites. Failures of such FRP-strengthened RC beams often occur by debonding of the FRP plate from the RC beam in a number of forms. Despite numerous theoretical and experimental studies on debonding failures of FRP-strengthened RC beams...

Tension stiffening is a characteristic behavior of reinforced concrete (RC) beams which is directly affected by the bond-slip property of steel bar and concrete interfaces. A beam strengthened with a near-surface mounted (NSM) technique would be even more affected by tension stiffening, as the NSM reinforcement also possess a bond-slip property. Yet assessing how much the tension stiffening of ...

This paper presents experimental research on reinforced concrete (RC) beams with external flexural and flexural–shear strengthening by fibre reinforced polymer (FRP) sheets consisting of carbon FRP (CFRP) and glass FRP (GFRP). The work carried out has examined both the flexural and flexural–shear strengthening capacities of retrofitted RC beams and has indicated how different strengthening arra...

This paper presents the results of an experimental campaign performed at the Laboratory of Materials and Structural Testing of the University of Salerno (Italy) in order to investigate the seismic performance of reinforced concrete (RC) beam-column joints strengthened with steel reinforced polymer (SRP) systems. With the aim to represent typical façade frames’ beam-column subassemblies found in...

A large share of reinforced concrete (RC) framed buildings is provided with wide beams being a type of beam allowing greater freedom in the architectural arrangement of interiors, beyond further advantage due to fewer formworks needed during the construction. Nevertheless, little attention has been devoted to the seismic vulnerability of this kind of framed RC buildings as well as to the study ...

During discharges in the Large Hetical Device (LHD), the plasma radiated power has been measured by several bolometry systems mounted on different ports of the machine. The spatial structure of the radiation during the period prior to the termination of Neutral Beam Injected (NBD heated plasmas was also investigated using multichannel bolometric diagnostics. During discharges with strongly radi...

It is shown that when certain conditions are met, the random dynamics of radiation in a ring cavity containing a nonlinear element can be described by means of a 2-D representation with a rapidly oscillating exponential. Such a representation generates strong mixing in the attracting region of the phase space and is equivalent to a certain random representation when the exciting signal contains...

In a recent paper G.V. Stupakov and P. Chen[1] have advanced the possibility of beam-beam interaction suppression in circular colliders for heavy particles such as muons and protons, by introducing a plasma at the interaction point. More recently and independently, A. Skrinsky [2] has suggested to use flowing liquid Li for the same purpose in a muon collider. This is an alternative that is only...
