The tensioned reinforced soil retaining wall, a novel retaining structure, utilizes either anchors or geosynthetic materials as reinforcements that contribute to load-bearing and friction within the structure. This study aims to explore the tension distribution and strain patterns in the reinforcements, and their influence on the reinforced soil retaining walls. To this end, tensile, direct shear, and pullout tests were conducted on GeoStrap@5-50 geotextile strips and TGDG130HDPE geogrids to evaluate the tensile strength and interface strength between the reinforcement and the soil.

Steel reinforcements in reinforced concrete structures are susceptible to corrosion under different exposure conditions. This can lead to some disadvantages, including concrete deterioration, reduced long-term service life, increased cost of the structure due to re-strengthening measures, and reduced overall durability of the structure. In order to solve these problems, the issue of comprehensive use of Fiber reinforced polymer (FRP) reinforcements as an alternative to steel bars is urgent. FRP reinforcements have specific advantages including corrosion resistance, high tensile strength, densi

The reinforcing steel embedded in concrete is generally protected against corrosion by the high alkalinity (pH = 12.5 to 13.5) of the concrete pore solution. The structural degradation of concrete structures due to reinforcement’s corrosion has an impact on the safety, serviceability and durability of the structure. The corrosion of reinforcements in the construction of a transport infrastructure (especially bridges), parking areas, etc., is primarily initiated by chlorides from de-icing salts. When corrosion is initiated, active corrosion results in a volumetric expansion of the corrosion pro

After cracking, the stiffness of the member along its length varies, which makes the calculation of deformations complicated. In a cracked member, stiffness is largest in the section within the uncracked region while remains smallest in the cracked section. This is because in the cracked section, tensile concrete does not contribute to the load carrying mechanism. However, at intermediate sections between adjacent cracks, concrete around reinforcement retains some tensile force due to the bond-action that effectively stiffens member response and reduces deflections. This effect is known as ten

The concept of designing mechanically stabilized earth (MSE) walls is divided into internal and external stability review methods, and one of the design factors required in internal stability analysis is the frictional characteristics between soil and geogrids for civil engineering applications.

Many research studies made on hundreds of MSE walls have shown that in order to get lower values of lateral earth pressure coefficients from an active condition on the backfill soil, thus lower exerted loads and stresses on the reinforcement, the wall needs to yield. This is typical of extensible polymer-based wall systems, such as geosynthetics. Steel systems, on the other hand, are very rigid and do not allow enough deformation on the wall to generate the active condition. For this research, steel reinforcement for MSE walls that behaves similar to geosynthetics was developed. This was done

Moreover, natural fibres have a set of beneficial traits, such as thermal insulation, thermal stability, biodegradability, and are inherently renewable.

Abstract Corrosion of the reinforcing steel is the primary cause of premature deterioration of reinforced concrete structures, and affects their functionality and safety. The non-corroding properties of GFRPs, their high tensile strength, and their high stiffness to weight ratio made them very attractive substitute to conventional reinforcing steel. The widespread acceptance of the usage of GFRP bars in concrete reinforcement applications has been delayed due to their relatively high initial costs, low elastic moduli and lack of design knowledge. There are also concerns about the behavior of G

Corrosion of commonly used steel reinforcements weakens the structural strength of concrete. To address this issue, research was conducted on concrete reinforcements in the form of polymer fibers. These polymer fibers need concrete bonding ability and good mechanical properties. This study investigates core-shell fibers produced from polyketone and polypro pylene mixed with a compatibilizer. The core-shell fibers were produced by coextrusion and drawing. The fibers were analyzed by tensile tests, a single fiber pull-out test, contact angle measurements, scanning electron microscopy, and thermo

Steel fibers are typically used in ultra-high performance concretes (UHPC) to impart flexural ductility and increase fracture toughness. However, the mechanical properties of the steel fibers are underutilized in UHPC, as evidenced by the fact that most of the steel fibers pull out of a UHPC matrix largely undamaged during tensile or flexural tests. This research aims to improve the bond between steel fibers and a UHPC matrix by using steel wool. The underlying mechanism for fiber-matrix bond improvement is the reinforcement of the matrix tunnel, surrounding the steel fibers, by steel wool. Si

Earthquakes, which can cause tremendous local stress and strain on infrastructure, can cause reinforced concrete (RC) bridges to collapse due to the concrete cracking and fracture of the steel reinforcement rebars. The fracture of longitudinal reinforcing steel due to low-cycle fatigue is one of the main causes of failure in RC structures under earthquake loading. The purpose of this research is to include the effects of low-cycle fatigue fracture of longitudinal reinforcing steel bars on the seismic performance of reinforced concrete bridge piers.

Early-age cracking in concrete decks significantly reduces the service life of bridges. This report discusses the application of various concrete mixtures that include potential early mitigation ingredients. Large-scale (7 ft × 10 ft) experimental bridge prototypes with similar restraint conditions found in actual bridges were poured with different concrete mixtures to investigate mitigation techniques. Portland cement (control), expansive Type K cement, internally cured lightweight aggregate (LWA), shrinkage-reducing admixture (SRA), and gypsum mineral were investigated as mitigating ingredie

Thermoplastic starches (TPS) are important bio-based, biodegradable polymers used in flexible packaging. However, their mechanical properties, processability, and high hydrophilicity limit their applications. This study examines the effects of chemical modifications and mechanical reinforcements on TPS matrices. Combinations of native and acetylated TPS, reinforced with native (CNF) and acetylated cellulose nanofibers (CNFA) at 1%, 2%, 3%, and 10%, were analyzed. TPS films were prepared with CNF using compression molding, followed by structural, morphological, mechanical, and hygroscopic analy

A patented active porcelain enamel coating improves both the bond between the concrete and steel reinforcement as well as its corrosion resistance. A Small Business Innovation Research (SBIR) program to develop a commercial method for production of porcelain-coated fibers was developed in 2015. Market potential of this technology with its steel/concrete bond improvements and corrosion protection suggests that it can compete with other fiber reinforcing systems, with improvements in performance, durability, and cost, especially as compared to smooth fibers incorporated into concrete slabs and b

U-rib cracks are one of the typical fatigue cracking modes in steel box girders. To address this issue, a double-sided reinforcement technique, incorporating microstructural damage by using steel rods and steel plates, was proposed. The mechanical performance of steel-rod reinforcement (SRR) and steel-rod plate reinforcement (SRPR) was evaluated using a series of compact tension-shear (CTS) specimens under varying loading angles. Subsequently, finite element models were employed to simulate and compare the maintenance effects of the two configurations. Finally, field application and monitoring

The composite rigid-frame bridge, where the steel girder and the reinforced concrete (RC) pier are rigidly connected, has a high bearing capacity and superior long-term performance. The steel girder-RC pier connection is the critical detail for the design of such a structural form. To this end, a detailed review of composite rigid-frame bridges in China and abroad was carried out to summarize various forms of connections and evaluate their applicability. A novel connection type was then proposed to improve the connective performance between steel plate girders and RC piers. Threedimensional fi
