“…Prestress technology has been widely used in reinforced concrete structures [1][2][3][4][5][6][7][8][9][10][11] to reduce deflection, increase structural stiffness, exploit the materials' mechanical strength, and ultimately, to create a lighter structural system to span longer distance. It is always the timber engineers' dream to develop an effective, practical, pure bio-based prestressed technology with in-situ flexibility that allows members to be cut and adjusted in-situ.…”

“…In recent years, the study of external prestressing system has been perfected. Regardless of the material being CFRP cloth [7], plate [8], sheet [9] or bar [10], new prestressed tension techniques have been developed. However, the carbon fiber plate prestressed tensioning device in previous studies was inseparable from tensioning tools and jacks.…”

In order to strengthen aluminum alloy bridge panels, a CFRP (Carbon Fibre Reinforced Plastics) plate is tensioned under the bottom plate to exert prestress. Installing the tensioning device under narrow bottom plates of bridge panels via traditional prestressing method is difficult; therefore, a new prestress tensioning technology based on Shape Memory Alloy (SMA) is employed to efficiently apply the prestress. The tensioning and anchorage device used in prestressing technology has been designed and manufactured. A tensile stress of 360Mpa was applied to the CFRP plate with the tensioning and anchorage device and then, load-bearing tests were performed on prestressed reinforced aluminum alloy and unreinforced bridge panels, respectively. Experimental results showed that the proposed CFRP prestressing technology was feasible and verified the application possibility of SMA as a prestress device in practical engineering. The new technology ensured that the desired prestress value was applied to aluminum alloy bridge panel and the strength and stiffness of aluminum alloy bridge panels reinforced with the proposed technology were significantly improved.

This paper aims to evaluate the hysteretic performance of prestressed concrete beams with aramid fiber‐reinforced polymer (AFRP) tendons. Eight beams were constructed and tested under cyclic loading, with test variables covering the type of prestressing tendons (AFRP and steel), the ratio of internal tendons to external tendons (3:0 and 1:2) and the bond condition of internal tendons (fully bonded, partially bonded, and unbonded). Results showed that the failure of all the beams was dominated by concrete crushing and nonprestressed rebars rupturing at pure bending sections. AFRP prestressed beams exhibited commensurate bearing capacity, displacement ductility, energy dissipation and residual deformation with steel prestressed beams. The combination of internal and external tendons, and using unbonded or partially bonded tendons could improve the ductility of AFRP prestressed beams. Additionally, the finite element (FE) models of AFRP prestressed beams were developed using ABAQUS based on the coupling method under the local coordinate system. The simulated results closely matched the experimental results in terms of the failure mode and load–displacement curve. Parametric predictions, including the unbonded length of AFRP tendon, partial prestressing ratio, jacking stress and concrete strength were presented to extend the experimental works.
