Fibre-reinforced polymer (FRP) rebars are being increasingly used to reinforce concrete structures that require long-term resistance a corrosive environment. This study presents structural performance of large scale two-way slabs reinforced with FRP rebars, and their performances were compared against conventional steel concrete. Both carbon (CFRP) basalt (BFRP) considered as replacement. Exper...

We prove a version of the quantum de Finetti theorem: permutation-invariant quantum states are well approximated as a probabilistic mixture of multifold product states. The approximation is measured by distinguishability under measurements that are implementable by fully-one-way local operations and classical communication (LOCC). Our result strengthens Brandão and Harrow's de Finetti theorem w...

This paper aims to investigate the effect of using different configurations near-surface mounted carbon-fiber-reinforced polymer (NSM-CFRP) strips on shear strength strengthened and rehabilitated reinforced concrete (RC) T-beams with internal stirrup spacing. The spacing was 50 150 mm. NSM-CFRP were at an inclination 45° spaced 75 A total eight beams tested in this study: two without as control...

 The structural reliability of torsional concrete beams strengthened with full and strip wrapping of carbon fiber reinforced polymer (CFRP) laminate is investigated. The first order-second moment reliability method has been applied to make a reliability assessment on the torsional capacity design by technical guideline in Iran. The code No.345 published by the Management and Planning Organizati...

Accepting the challenge of the future in the field of civil engineering smart structure applications, the province of Manitoba is undertaking the responsibility of constructing the first bridge in Canada totally prestressed and reinforced for shear by cru:bon fibre reinforced plastic (CFRP) reinforcement. Portion of the concrete deck slab is also reinforced exclusively by FRP reinforcements. Th...

In this study, a carbon nanotube (CNT) buckypaper was interleaved in carbon-fiber-reinforced polymer (CFRP) composite to improve the interlaminar fracture toughness. Interleaving film of laminate-type poses risk deteriorating in-plane mechanical properties. Therefore, shear modulus and strength were measured prior estimating To evaluate effect on toughness CFRP, double cantilever beam (DCB) end...

this experimental study is intended to evaluate the effectiveness of a near surface mounted (nsm) technique using bars made of carbon fabrics (bmcf) for strengthening of rc beams. when the amount of nsm reinforcement in strengthening of rc beams is low, the failure is likely to be due to debonding of individual reinforcing rod and in this case improved bond properties as well as proper anchorin...

In this paper, an experimental study is presented on the influence of PET warping on shear performance, such as diagonal shear cracking load, peak load, and energy dissipation of RC columns with stirrup corrosion before strengthening. The experimental program involved an electrochemical process to accelerate the migration of chlorides from an external electrolyte into the tested columns, a wett...

The conventional strengthening strategy on the connection between the steel pile cap and reinforced concrete footing requires a series of complicated processes such as the distribution of reinforcing bars, their anchorage into concrete, and the usage of shear keys. This study investigates the structural performance of steel pile caps strengthened with newly proposed perfobond shear connectors s...
