“…The first applications of HPC in prestressed bridges were recorded in the 1980s, e.g., the East Huntington Bridge over the Ohio River or the Tower Road Bridge in the state of Washington [ 6 ]. The term high-performance concrete refers to concrete that meets a wider range of requirements regarding its quality, affecting the increased durability of the structure, and thus it is not limited only to the compressive strength [ 7 ].…”

“…The proposal for a hybrid algorithm of FAHP, FANP, and TOPSIS methods applied to issues connected with the optimization of maintenance activities at the bridge is given in the work [ 42 ]. One of the methods [ 6 ] applied less frequently is the Weighted Sum Method (WSM), which, however, does not allow for the application of fuzzy evaluation [ 43 , 44 ].…”

The selection of material solutions is a basic decision-making problem that occurs in engineering issues. It affects the entire life cycle of a building structure, its safe use, maintenance costs, and a need to meet requirements for sustainable development, including recycling. This paper aims at selection of the optimum composition of HPC designed for monolithic girder structures of post-tension bridges. For the analysis, a set of 12 new-generation concretes (HPC) was designed, made, and tested. A full-scope set of evaluation criteria was created and then the optimal alternative was selected. For this purpose, an advanced hybrid algorithm combining EA FAHP (Extent Analysis Fuzzy Analytic Hierarchy Process) and FuzzyTOPSIS (Fuzzy Technique for Order Preference by Similarity to an Ideal Solution) methods was used. The obtained results indicate a possibility for the practical application of the proposed algorithm by decision-making engineering staff. It can also be the basis for further research on application compared to other material and design solutions and, depending on the issue, different combination of aggregated methods.

“…In 1993, The Federal Highway Administration (FHWA) introduced the high performance concrete (HPC) designation for the construction of bridge use with eight performance characteristics; four for concrete durability and four for its strength. The definition consisted of four durability characteristics that include freeze-thaw resistance, scaling resistance, abrasion resistance and chloride penetration, while the four strength characteristics include compressive strength, modulus of elasticity, drying shrinkage and creep (Russell, 2013). High-strength concrete (HSC) allows the use of longer span lengths, wider girder spacing, shallow girders, or their combination resulting into economical structures.…”

“…High-strength concrete (HSC) allows the use of longer span lengths, wider girder spacing, shallow girders, or their combination resulting into economical structures. Inspection for constructed HPC reinforced concrete bridge deck depicts cracks from none to more than expected (Russell, 2004 In 2006, FHWA proposed new revision for eleven characteristics and three grades of performances of HPC (Russell, 2013). The eleven performance characteristics includes: freezethaw (F/T) durability, scaling resistance (SR), abrasion resistance (AR), chloride penetration (CP), alkali-silica reactivity (ASR), sulfate resistance (SR), flowability, strength; elasticity, drying shrinkage, and creep.…”

This research investigates the use of glass fiber reinforced polymer (GFRP) bars in bridge decks and ultra-high performance fibre-reinforced concrete (UHPFRC) as filling materials in (i) panelto- panel closure strips between transverse precast full-depth deck panels (FDDPs) supported over girders and (ii) the shear pockets for the panel-to-girder connection. The experimental research program included three phases. Phase I examined pullout strength of straight-end and headed-end GFRP bars embedded into UHPFRC to determine the required closure strip width to develop bar full strength. Phase II included the development and study of closure strip details incorporating UHPFRC as joint-filling materials and GFRP bars projecting into the joint. Three joints of width 200 mm between precast FDDPs were developed, namely: angle-shape joint (Ajoint), C-shape joint (C-shape), and zigzag-shape joint (Z-joint), with 175-mm projecting length of GFRP bars into the joint. Two series of 2500x600x200 mm one-way slabs were cast to investigate the flexural strength of the jointed precast slabs compared to cast-in-place slabs. Two types of concrete were used to fabricate the precast FDDPs, namely: normal concrete (NSC) and high-performance concrete (HPC). Correlation between experimental results and available design equations for moment and shear capacities, as well as CHBDC and AASHTO-LR applied factored design moments, was performed. All specimens failed in either flexural or flexural-shear mode outside the UHPFRC-filled joint. Phase III included testing three pairs of 3700x2500x200 mm laterally-restrained precast FDDPs incorporating the three developed joint details in the transverse direction of the girders. Each pair of specimens was tested under 600x250 mm wheel loading located beside the closure strip, considering (i) constant amplitude fatigue (CAF) loading up to 4 million cycles followed by increasing static loading to-collapse, and (ii) incremental variable amplitude fatigue (VAF) loading to-collapse. The failure mode of the tested slabs was punching shear, with the transverse UHPFRC joint diverting the extension of the punching shear plane to the adjacent precast FDDP segment. Results of fatigue load tests on the three-jointed pairs of slabs showed high fatigue performance. A new prediction model for fatigue life of the GFRP-reinforced, UHPFRC-filled jointed deck slabs was developed.
