The static and fatigue performance of reinforced concrete beams strengthened by strain-hardening fiber-reinforced cementitious composite is investigated.
Two series of strengthened beam specimens are prepared with different thicknesses of the enhancement layer (40 mm and 50 mm), and three fatigue stress levels (,and ) are by: 2.
A total of 10 steel-concrete composite beams were tested under static and fatigue loads. The effect of corrosion rate of shear studs on the beam performance was carefully examined.
Based on the experimental investigations, the following Cited by: 1. The principal objectives of research conducted to investigate the influence of FRP in respect of static and fatigue response of HSFRC ing an analytical based model with the available experimental model for predicting the performance parameters of HSFRC analytical based model have been analysed for static and fatigue load Author: Stephen Jebamalai Raj J, Vinod Kumar M.
The performance of steel fiber reinforced concrete under flexural fatigue loading is examined in terms of fiber content ( to percent by volume), fiber aspect ratio (47 to ), and fiber. This paper focusses on the performance of bolted shear connectors embedded in concrete slab when subjected to static and fatigue loading.
The static and fatigue capacities of shear connectors between concrete slabs and steel beams are important issues, as existing composite structures experience complex loadings during their functional working : Seyedeh Maryam Hosseini, Mohammad Shafiqul Mamun, Olivia Mirza, Fidelis Mashiri.
Fatigue tests of reinforcing bars at static loads are not accompanied by any problems, yet tests of reinforcing bars at changing loads pose certain difficulties related to the fact that fatigue cracks are usually generated in the area where test specimens are fixed in the jaws of a testing machine, i.e.
where significant notches are present. The Static and Fatigue Performance of Concrete Beams with High Strength Deformed ().

A high strength concrete with day compressive strength of 95 MPa was used along with a normal strength concrete of 42 MPa as control. Three different sizes of deformed bars (10, 16, 25 mm) and one smooth bar (25 mm) were used.
The investigation was conducted to study the fatigue behavior of steel fiber reinforced high-strength concrete (SFRHSC) beams. A series of 5 SFRHSC beams was conducted flexural fatigue tests at.
bars from manufacturer A with a minimum stress of 6 ksi (41 MPa) and a fatigue life in excess of 2 million cycles. The researchers also reported that the fatigue limit of interest to the bridge designer is not sensitive to concrete beam dimen-sions, concrete material properties, reinforcing bar size, rein.
In the frame of an ongoing research project at the Carinthia University of Applied Sciences (CUAS) high strength concrete members reinforced with high strength steel and GFRP-bars have been tested. Concerning the structural applications of steel fiber reinforced expanded-shales lightweight concrete (SFRELC), the present study focuses on the flexural fatigue performance of SFRELC superposed beams with initial static-load cracks.
Nine SFRELC superposed beams were fabricated with the SFRELC depth varying from 50% to 70% of the whole sectional depth, and the volume fraction of. Khader, A., â Evaluation of MMFX Corrosion-Resistant Steel Dowel Bars in Concrete Pavements,â Report WI, Wisconsin DOT.

This paper presents experimental results of 44 composite beam structures tested under static and fatigue loads. While designing the specimens, variables considered included: (1) the number of shear studs; (2) reinforcing method (deformed bars versus welded wire fabric); and (3) load levels and load ranges for fatigue tests.
The objective of the presented study is to examine the effects of glass fiber reinforced polymer (GFRP) composite rehabilitation systems on the fatigue performance of reinforced concrete beams.
Results indicate thut concrete keys can withstand stresses in pure shear as high as psi and that the keys exhibit higher shear strength when subjected to dynamic loads than when stressed by static loads. Tests also indicate that the strength and quality of the gravel are probably major factors governing the strength of the keys.
(J.R.D.). Fatigue is the process of mechanical degradation of a material, which leads to its collapse. Repeated load applications with a maximum value lower than the one that provokes the static failure of the material, causes internal damage in the material that, progressively, reduces its mechanical capacity until it finally collapses.
The increasingly widespread use of high-strength concretes permits. The aim of this paper is to describe the performance of reinforced concrete (RC) beams retroﬁtted the FRP has high strength to weight ratio, good chemical resistance and is easy to handle, thus reducing the deformed reinforcing bars according to ACI is.Title: High-Strength Deformed Steel Bars for Concrete Reinforcement Author(s): Sidney A.
