Thermal effects on transfer length and prestress losses in CFRP prestressed prisms

This paper presents the results of an investigation on the use of prestressing carbon fiber reinforced polymer (CFRP) systems in bridge girders. Unlike steel, thermal incompatibilities between concrete and CFRP can affect the prestressing force and the long-term bonding between CFRP prestressing and the concrete. In this research, 54 CFRP pre-tensioned concrete prisms were tested to evaluate the transfer length and associated long-term prestress losses over a period of one year. Then, the specimens were subject to thermal cycles to represent the severe seasonal temperature change for a bridge in service. Experimental results suggest a degradation of the bond and increase of the transfer length for prestressing CFRP cables and bars. Shorter transfer lengths and better bond characteristics under thermal fluctuations were achieved for prism prestressed with CFRP cables compared to CFRP bars. A finite …

Experimental investigation of full-scale post-tensioned composite AASHTO beams prestressed with carbon-fiber-reinforced polymer cables

Test results consistently indicate that while the overall behavior of CFRP-prestressed and steel-prestressed concrete beams are similar, several significant differences must be considered. These differences are primarily associated with the linear-elastic nature of the CFRP reinforcement. The load-deflection curve of a steel-prestressed concrete beam exhibits three stages, which reflect the elastic (before and after cracking) and inelastic properties. However, when CFRP is used for prestressing, the concrete beam exhibits only two stages: before cracking and after cracking up to the ultimate load. Because the modulus of elasticity of CFRP is low compared with that of steel, the curvatures and deflections induced in CFRP are larger than those induced in steel under the same level of flexural loading. 2 The deformation of CFRP-prestressed concrete beams at the point of rupture of CFRP tendons is smaller than that of the steel-prestressed concrete beams due to strain hardening in steel. 3As explained in the literature review section, below, a limited number of studies investigated the behavior of full-scale post-tensioned beams with unbonded prestressing CFRP. Previous research showed that under fatigue loading, failure in these types of beams typically occurs at the anchorage-tendon assembly, which leads to a premature failure of the system. Recently, there have been advancements in the tendon-anchor assembly design, therfore the performance of the assembly when used in full-scale beams with straight or draped profile configurations is investigated in this paper. In addition, the accuracy of the design guidelines to determine the ultimate …

A New Insight into the Design Compressive Strength of Ultra-High Performance Concrete

Compressive strength is one of the most critical mechanical properties of various types of concrete and is the main input variable for structural concrete design. Recently, with the advances in concrete technology, applications of fiber-reinforced concrete (FRC), including ultra-high performance concrete (UHPC), have grown rapidly. These new types of concrete are well known to exhibit superior mechanical characteristics such as compressive strength, fracture toughness, and durability compared to conventional concrete and thus are popularly used in urgent repair jobs where compressive strength is an important parameter to determine the required curing time until open to the public. Considering the importance of compressive strength in practice, this study aims to evaluate the effect of age and maturity on the compressive strength characteristics of three different types of concrete, namely UHPC with micro and macro steel fibers, FRC, and plain concrete, and to propose a new design strength criterion for UHPC. To this end, 180 concrete cube specimens were tested at 12 different ages between 3 and 126 days. The results indicated that irrespective of the type and presence of fibers, UHPC gained more than 90% of their ultimate compressive strength after only 21 days, while FRC and plain concrete specimens required a longer time (i.e., 28 days) to achieve 90% of their ultimate strength. Therefore, UHPC may adopt a 21-day compressive strength as a design input instead of a 28-day compressive strength commonly required for structural concrete specified by many codes of practice. Moreover, the obtained experimental results were compared …

Flexural Behavior of Full-Scale, Carbon-Fiber-Reinforced Polymer Prestressed Concrete Beams Authors' response

■ In the past few decades, carbon-fiber-reinforced polymers (CFRPs) have been researched and implemented in concrete structures to address problems related to environmental durability and increase the service lives of bridges. This paper addresses a gap in the research and application of CFRP prestressing elements in large-scale bridge beams.■ Eight full-scale American Association of State Highway and Transportation Officials (AASHTO) Type I prestressed concrete beams pretensioned with CFRP cables, CFRP bars, or steel prestressing strands were tested under monotonic and fatigue loading to evaluate the flexural behavior, load-deflection behavior, and ultimate capacity of the beams.

Corrosion Behavior of Conventional and Corrosion-Resistant Steel Reinforcements in High-Performance and Ultra-High-Performance Concrete.

This paper presents the findings of an experimental study on the corrosion performance of both conventional and corrosionresistant steel reinforcements in normal-strength concrete (NC), high-performance concrete (HPC), and ultra-high-performance concrete (UHPC) columns in an accelerated corrosion-inducing environment for up to 24 months. Half-cell potential (HCP), linear polarization resistance (LPR), and electrochemical impedance spectroscopy (EIS) methods were used to assess the corrosion activities and corrosion rates. The reinforcement mass losses were directly measured from the specimens and compared to the results from electrochemical corrosion rate measurements. It was concluded that UHPC completely prevents corrosion of reinforcement embedded inside, while HPC offers higher protection than NC in the experimental period. Based on electrochemical measurements, the average …

Shear Design of Prestressed Concrete Girders Using FRP as Auxiliary Reinforcement

Concrete cracking diminishes the protection to embedded metallic reinforcements in aggressive environments. Consequently, corrosion ensues leading to loss of mechanical properties and reinforcement area and, in some cases, to failure of structural members. As such, more durable and sustainable new materials such as Fiber Reinforced Polymers (FRPs) have been gaining attention from bridge engineers. Current design guide specifications do not address all limitations related to the design of prestressed concrete girders using FRP auxiliary (non-prestressed) reinforcement, whose mechanical properties are different than traditional carbon steel. Furthermore, these guides are based on empirical models and scattered experimental data, resulting in a barrier against wider adoption of FRP as auxiliary reinforcement. Therefore, design provisions based on a more refined analytical approach followed by an …

PC Girder-to-RC Deck Connection: Interface Shear Transfer with GFRP Reinforcement

In the case of bridge construction, the composite action between a precast, prestressed concrete (PC) girder and the reinforced concrete (RC) deck is typically of critical importance. When the PC girder is made with carbon FRP tendons and glass FRP (GFRP) auxiliary reinforcement, the possible contribution of GFRP to the interface shear resistance mechanism should be investigated and, if demonstrated reliable, should be accounted for in the design.Most of the research related to interface shear transfer has utilized steel bars as reinforcement, while FRP reinforcement as a shear transfer mechanism has received very little attention both experimentally and analytically. For this reason, the inclusion of GFRP to provide shear resistance across a given plane is an important topic. Furthermore, only a few design specifications include provisions for the calculation of the interface shear transfer design strength when …
