Ultra-high-performance concrete (UHPC) is a form of cementitious composite that has been the most innovative product in technology over last three decades. broadly employed for design numerous forms construction owing to its excellent mechanical characteristics and durability, studies on behavior have grown fast While utilization ultra-high-performance bridge engineering (BE) limited high costs, little recognized about UHPC various BE elements. As result these issues, comprehensive review...
The present study experimentally and numerically investigates the behavior of ten self-compacting reinforced concrete (SCRC) beams strengthened by various means externally bonded glass fiber polymer (GFRP) strips subjected to pure torsion. experimental matrix is designed explore impact number GFRP layers, width strengthening spacing between those layers on ultimate torsional capacity, angle twist, ductility, failure patterns with respect an un-strengthened specimen. Tests revealed that...
Abstract In this paper, the effectiveness of strengthening by a wooden plate for reinforced concrete (RC) beams that incorporate waste sawdust (SD) as partial substitute fine aggregate (sand) has been investigated. To end, two types mixtures were made: normal (NC) and (SDC), which was made substituting 15% volume sand with SD. Five RC (100 mm in depth, 200 width, 1500 length) experimentally tested flexural behavior under four-point loading. Three schemes used study. The first scheme only...
This paper presents a numerical investigation of the flexural behavior timber beams externally strengthened with carbon-fiber-reinforced polymer (CFRP) sheets. At first, accuracy linear elastic and elastic-plastic models in predicting bare was compared. Then, two modeling approaches (i.e., perfect bond method progressive damage technique using cohesive zone model (CZM)) were considered to simulate interfacial between FRP timber. The validated against published experimental data, most...
Carbon fiber-reinforced polymer (CFRP) is attractive to serve as reinforcements for concrete members under harsh environmental conditions. Previous studies show that strip-shaped CFRP stirrups satisfactory replace steel beams shear, but the shear resistance mechanism of strip-shape remains unclear. To fill this research gap, study conducts a comparative analysis examine effects different types (CFRP or steel) on distribution characteristics cracks and variation in components with varying...
This study presents a numerical investigation on the shear behaviour of shear‐strengthened reinforced concrete (RC) beams by using various ultrahigh performance fibre‐reinforced (UHPFRC) systems. The proposed 3D finite element model (FEM) was verified comparing its results with those experimental studies in literature. validated is used to analyse crucial parameters, which are mainly related design RC and UHPFRC layers, such as effect span‐to‐depth ratio strengthened or nonstrengthened...
This study aims to review the research studies available in literature that examines mechanical properties and optimum mixing ratios of ultra-high performance fiber-reinforced concretes (UHPFRCs). In addition a comparison between UHPFRC, high-performance concrete (HPC), normal strength (NSC). The included this were compiled under different headings explained concisely. Subsequently, best UHPFRC mixture was determined be obtainable with 2% 3% steel fiber content water/cement ratio <0.2....
Although pile cap bases of structures are the most significant element in construction and one difficult parts strengthening applications, previous studies on this element, particularly strengthening, quite limited. The extensively utilized, highly efficient, simple to implement solution is ultra-high performance concrete (UHPC). In study, six-half scaled beams were prepared experimentally tested. Three them strengthened with UHPC (one shear connectors only, steel mesh fabric (SMF), punching...
In this research, behavior of RC columns reinforced with recycled polyethylene terephthalate (PET) and steel fibers (SF) was experimentally investigated. The experimental work includes testing 8 dimensions 150x150x1000 mm subjected to axial loading up failure. Three volume fractions (1%, 2% 3%) were carried out for both PET SF. axial/lateral displacement the column transverse/vertical strain versus load bars recorded. peak load, yield failure mode, ductility stiffness studied in detail....
This paper presents the efficiency of using prefabricated ultra‐high performance fiber reinforced concrete (UHPFRC) plates in shear strengthening (RC) beams experimentally and numerically finite element method. In order to ensure high quality facilitate process on site applications, it has been considered apply UHPFRC as a plate pasted surface epoxy. Tested specimens included four strengthened besides three control beams. Strengthening RC was based use two different techniques; (a) one...
