Concrete is characterized by the type of aggregate or cement used, by the specific qualities itmanifests, or by the methods used to produce it. In ordinary structural concrete, the character of the concrete is largely determined by a water-to-cement ratio. The lower the water content, all ...
The steel fiber concrete can be made of various fibers of different material, section and longitudinal shapes, and length–diameter ratio, and manufactured by different construction methods. From:Principles of Reinforced Concrete,2014 Add to Mendeley ...
Steel-concrete composite structures have been used extensively in bridge structures, both highway and railway bridges, due to the benefits of combining the two construction materials, their higher span-to-depth ratio, reduced deflections, and higher stiffness ratios than traditional steel or concrete ...
Table 3 Experimental and theoretical values of ultimate average bond strength under different corrosion rate of steel strands. Full size table Figure 7 The relationship between the corrosion rate of steel strand and the ratio of the test value of the ultimate bond strength to the calculated value....
By using stiffness characteristic value and core tube aspect ratio H/b as main parameters,nonlinear static analysis is employed to the calculation model of steel reinforced concrete frame-reinforced concrete core wall hybrid structure in the paper.According to the 22 groups of results,the problems ab...
Reinforcing steel is also classified according to its elongation at ultimate strength and depending on the hardening ratio, where three different ductility classes for steel reinforcing bars are defined. The classes “A”, “B” and “C” belong to A gt higher than 2.5, 5.0 and 7.5% and by...
The relatively low influence of the out-of-plane load is caused by the low slenderness ratio of the infill panel in combination with the strong frame-infill connections. 5.2 Out-of-plane behaviour Table 12 comprises the comparison of out-of-plane load–displacement curves for pure out-of-...
The elastic modulus (Es) was 176GPa, and the Poisson-ratio (ν) of the steel was 0.3. Table 2 Mechanical performance of steel. Full size table In the test, the reference concrete compressive cube strength (fcu) at the 28 days was designed as 40 MPa. Based on the previous reference25,...
Compared with steel, FRP materials have many advantages including high strength-to-weight ratio, excellent corrosion resistance and low thermal conductivity [1–7]. However, due to the linear elastic behavior up to failure and brittle characteristics of FRP, different design methods should be adopted...
Fig. 2. (a) Manufactured steel fibres (b) Sample of recycled fibres from tire waste. As it can be seen in Table 2, the main differences between SF and RF is their density, tensile strength and aspect ratio, being that the latter two properties have direct influence over mechanical perform...
