Behavior of concrete beams reinforced with hybrid steel ...

2018-12-1  For specimens with FRP rebars as upper and lower reinforcement, the failure was crushing in concrete which is the unfavorable brittle failure in spite of increasing the area of reinforcement. Therefore, providing steel rebars to the FRP rebas in the top and bottom reinforcement ensures the desirable ductile flexural behavior.

2016-3-15  The stroke of the testing machine was gradually increased until flexural failure was reached, manifested by concrete crushing. Fig. 2 shows load-mid-span deflection curves of the beam specimens. In beams with reinforcement ratios of 0.15% and 0.39%, concrete crushing was accompanied by rupture of the longitudinal steel.

Anchoring To Concrete - PDHonline

2017-6-22  A concrete anchor is a steel shaft either cast into concrete at placement or post-installed after the concrete has hardened. Cast-in anchors are threaded shafts with a buried end termination of a hex head, threaded nut, or 90° (L-) or 180° (J-) hook, or headed (non-threaded) studs welded to a

2011-8-13  For concrete crushing, the Whitney rectangular stress block is used to approximate the concrete stress distribution at ultimate strength conditions. For FRP reinforcement, the linear-to-failure stress-strain relationship must be used. If the FRP reinforcement ruptures, sudden and catastrophic failure can occur. Therefore, concrete crushing has ...

2019-11-11  This paper proposes a new kind of U-type reinforcement ferrule (URF) connection for the assembly of precast concrete (PC) components, which has a good fault-tolerance ability and low cost of construction with a simple post-grouting process. The modified connection features welded U ferrules, which can increase the bonding mechanism and internal stress transmission in the spliced region.

2013-3-6  The crushing strength of concrete is influenced by a number of factors in addition to the water/cement ratio and the degree of compaction. The more important factors are: (1) Type of cement and its quality. Both the rate of strength gain and the ultimate strength may be affected. (2) Type and surface texture of aggregate.
