Compressive Strength of Confined Concrete in CCFST Columns
This paper presents a new model for predicting the compressive strength of steel-confined concrete on circular concrete filled steel tube (CCFST) stub columns under axial loading condition based on Artificial Neural Networks (ANNs) by using a large wide of experimental investigations. The input parameters were selected based on past studies such as outer diameter of column, compressive strength...
متن کاملPlastic Deformation Characteristics of Continuous Confined Strip Shearing Process Considering the Deformation Homogeneity and Damage Accumulation
In the present investigation, two dimensional elastoplastic finite element analysis was conducted to assess the deformation characteristics of Al 1100 alloy during continuous confined strip shearing (C2S2) process. The results of simulations showed that the plastic strain distribution across the deformed sample is non-uniform irrespective of the amount of friction and C2S2 die angle. The most u...
متن کاملBond of Reinforcement in High-Strength Concrete
This paper describes an examination of the development of tension lap splices in high-strength concrete and the applicability of the restriction in the ACI 318 code where the values of √fc′ used to calculate development length shall not exceed 100 psi. The focus is on the development of splices with Grade 60 epoxy-coated and uncoated bars in normalweight concrete. A summary of the behavior of b...
متن کاملBond Strength of Hot – Dip Galvanized Reinforcement (b500b) with Concrete
P. Pokorný, D. Dobiáš, M. Vokáč – Czech Technical University – Klokner Institute, Prague, Czech Republic This paper evaluates the effect of initial corrosion damage to the surface of the hot dip galvanized steel coating in fresh concrete on its final bond strength. The tests were performed on uncoated and hot-dip galvanized ribbed reinforcements. The measurement of bond stress (τm) according to...
متن کاملExperimental Study of Damage Evolution in Circular Stirrup-Confined Concrete
This paper presents an experimental study on circular stirrup-confined concrete specimens under uniaxial and monotonic load. The effects of stirrup volume ratio, stirrup yield strength and concrete strength on damage evolution of stirrup-confined concrete were investigated. The experimental results showed that the strength and ductility of concrete are improved by appropriate arrangement of the...
