Abstract Fiber Reinforced Concrete FRC can be used for a variety, of applications. Fibers are utilized in concrete crack requiring reduction physical property protection, drying and improved strength toughness, increased service life decrease bleeding from water, permeability, construction value. The utilization sisal, natural fiber with mechanical efficiency, as reinforcement an exceeding matr...

The orientation of the fibers in UHPC is decisive for tensile strength and failure components. mold filling strategy during casting structural components dictates flow routing thus fiber orientation. In addition, also affects behavior suspension. measurements rheological properties concrete rheometers, strongly scattering often occur. this paper, a novel model viscoplastic fluids investigated C...

In the present study, performance of Reinforced Concrete (RC) beams which were strengthened with Ultra High Performance Fiber (UHPFRC) and dowels at interface was investigated. RC a length 2.2 m UHPFRC layers tensile side. Before application layers, between roughened. During testing, slips recorded using Linear Variable Differential Transformers (LVDTs). The tested under four-point flexural tes...

The performance of the interface between fiber reinforced polymer (FRP) composites and concrete is one of the key factors affecting the behavior of strengthened reinforced concrete (RC) structures. Existing laboratory research has shown that RC beams strengthened with FRP sheets usually fail because of either debonding of the impregnated fabric from the concrete substrate or fracture of the FRP...

The concept of an integrated strengthening and damping retrofit system was proposed to design reinforced concrete (RC) columns for their optimal performance under multi-level earthquake hazards. As illustrated in Figure 1, the system consisted of fiber reinforced polymer (FRP) sheets wrapping around a column and viscoelastic (VE) layers on the FRP sheets. The motion of the outer surface of the ...

an experimental program was carried out to investigate the behavior of steel, fiber reinforced concrete (sfrc) under abrasion and cycles of freeze and them. compression and flexural tests were also performed in order to reach a comprehensive conclusion of the response. in total, over 200 specimens were tested the test variables included two concrete strength., (i. e., 28 mpa as normal strength ...

 The structural reliability of torsional concrete beams strengthened with full and strip wrapping of carbon fiber reinforced polymer (CFRP) laminate is investigated. The first order-second moment reliability method has been applied to make a reliability assessment on the torsional capacity design by technical guideline in Iran. The code No.345 published by the Management and Planning Organizati...
