the load transfer mechanisms of cable bolts differ from those for normal rebar bolts. the cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. the tendon strength can be evaluated by the tensi...

This study focused on the residual strengths of reinforced concrete beams with heavy deterioration. This work is based on experimental investigation of reinforced concrete beams naturally corroded over 30 years. Visual inspection was firstly conducted and the concrete cracking, spalling of concrete cover, corrosion of rebar were recorded. Material tests on concrete and corroded rebar were also ...

Six RC short-limb shear walls with an L-shaped section, constructed high-strength rebar and concrete, were loaded to destruction pseudo-static loading. Experimental results discussed compared horizontal in detail. Different failure modes obtained, such as flexure-dominated for specimens aspect ratio of 2.8 2.15 bending-shear 1.75. With a decrease the ratio, ductility decreased, whereas increase...

Depending on the desulfurization reaction temperature, it can be divided into fly ash generated at hightemperature furnace zone and at low-temperature flue gas zone. For simulating those two kinds of desulfurization ash, the ordinary fly ash mixed with different weight percentage of CaSO4·2H2O is divided into 2 groups, the first group is followed by calcining at 900°C, another drying at 100°C. ...

This paper explores a set of new equations to predict the bond strength between fiber reinforced polymer (FRP) rebar and concrete. The proposed equations are based on a comprehensive statistical analysis and existing experimental results in the literature. Namely, the most effective parameters on bond behavior of FRP concrete were first identified by applying a factorial analysis on a part of t...

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

The use of combined reinforcement in the form external S275 steel tape and A1000 high-strength rebar is generally interesting for research. a package enables better choice rational cross-section area by varying diameter or width tape. In addition, an issue research limit strain values different strength classes since they can differ significantly, which affects operation structure as whole. For...
