This paper presents the finite element modelling of shear-critical reinforced concrete beams strengthened with U-wrapped CFRP fabrics using ATENA. Fracture-plastic constitutive models, implemented in context smeared crack and crush-band approach, were employed to represent nonlinear behaviours concrete. U-wraps modelled as rein­forcement bonded surface an interface element, considering appropri...

The behaviour of Carbon Fibre Reinforced Polymer (CFRP) strengthened vertically curved beams Steel Circular Hollow Sections (SCHS) was studied. Sixteen numbers with 1200 mm span having four radii curvatures; 0 mm, 2000 4000 and 6000 were tested under three-point bending tests. A range CFRP lengths up to 1000 selected. maximum performance noted when the ratio between length total is 0.625. Four ...

This paper describes a method for designing robots to learn self-motivated behaviors rather than externally specified behaviors. Self-motivation is viewed as an emergent property arising from two competing pressures: the need to accurately predict the environment while simultaneously wanting to seek out novelty in the environment. The robot’s internal prediction error is used to generate a rein...

This study concerns improvement of flexural stiffness/strength of concrete members reinforced with externally bonded, aluminum-glass fiber composite (AGC) beams. An experimental program, consisting of seven reinforced concrete slabs and seven reinforced concrete beams strengthened in flexure with AGC beams, was initiated under four-point bending in order to evaluate three parameters: the cross-...

methods are proposed to develop idealized moment-curvature response curves of slender rectangular rc wall sections with uniformly distributed longitudinal reinforcement, using limit states, namely, cracking of concrete in tension, tensile yielding of reinforcement layers, and compression failure of concrete. it is recommended that tensile yielding of an inner layer of reinforcement is considere...
