where. f y = the yield stress of the steel reinforcement (we will use 60 ksi in all examples). f c ' = the compressive cylinder strength of the concrete (ksi). ρ = the steel ratio, A s /(bd) For given values of f y and f c ', the relationship between R and ρ can be computed from Equation 5.13. Appendix Table A-5.9 gives typical values of R and ρ for f y = 60 ksi, and …
The mean peak strengths corresponding to the carbon fiber-bar reinforced concrete specimens after high-temperature action at 25, 200, 400, and 600 °C are 1.13, 1.13, 1.21, and 1.19 times that of ...

Nonlinear finite element (FE) analysis of reinforced concrete (RC) structures is characterized by numerous modeling options and input parameters. To accurately model the nonlinear RC behavior involving concrete cracking in tension and crushing in compression, practitioners make different choices regarding the critical …
This method makes use of the hydraulic forces exerted to the moving jaws of the bursting machine to Using hydraulic forces to burst the concrete or rock material into smaller pieces within a short period of time, with very high efficiency. There are two different bursting equipment, which are handheld bursting tip and bursting head:
1.3.1. "Implosion" (Pipe Crushing) In the "implosion" system, the bursting tool consists of two parts: a crushing head, which breaks the existing pipe and forces the pipe fragments inwards into the pipe void, and a steel cone, which pushes the crushed pipe fragments …

Guidelines for Pipe Bursting. 1.3.1. "Implosion" (Pipe Crushing) In the "implosion" system, the bursting tool consists of two parts: a crushing head, which breaks the existing pipe and forces the pipe fragments inwards into the pipe void, and a steel cone, which pushes the crushed pipe fragments and soil outwards, making room for the new pipe.
Concrete Bursting or Hydraulic Bursting is a safe, quiet and environmentally friendly method of weakening and demolishing concrete structures, through a vibration free demolition technique. The process enables the removal of lumps of concrete without the use of large machinery, therefore can be used in tight or problematic spaces.
A macromodel that represents the behavior of reinforced concrete members that accounts for strength degradation due to bond slip and crushing of concrete is developed. The model consists of ...

As per the British standards, concrete is capable of carrying a strain up to 0.0035 and steel starts yielding at a strain of 0.002 and it can increase greater than the concrete. When the axial stress exceeds a certain amount resulting in concrete strain grater than 0.0035 concrete will fail suddenly. It will be a sudden crushing of concrete.
Over the past decades, considerable efforts have been made to quantify the bursting forces in the post-tensioned anchorage zones based on the simplified model or fitting formulas, however reproducing the transverse stress distribution is still a challenging topic, which is also important to detail the reinforcing details in the anchorage zones, …
