Numerical crack modelling of tied concrete columns under compression

C. Bosco,S. Invernizzi 사단법인 한국계산역학회 2012 Computers and Concrete, An International Journal Vol.10 No.6
In the present paper the problem of monotonically compressed concrete columns is studied numerically, accounting for transverse steel reinforcement and concrete cracking. The positive confinement effect of the ties on the core concrete is modeled explicitly and studied in the case of distributed or concentrated vertical load. The main aim is to investigate the influence of transverse reinforcement steel characteristics on the column load carrying capacity and ductility, in order to provide an evaluation about some standards requirements about the class and ductility of steel to be used for ties. The obtained results show that the influence of transverse reinforcement steel class of ductility is negligible both on the column load carrying capacity and on its ductility. Also the dissipated energy is basically unchanged. In view of these evidences, some standards requirements about the steel class of ductility to be used for ties appear to be rather questionable.

Abstract Proton-conducting polymer electrolyte systems (PVP-MSA), with polyvinylpyrrolidone as a host polymer and methanesulfonic acid as a proton donor, were prepared by a facile solution-cast technique. The effects of plasticizer, dimethyl carbonate, on the electrical and electrochemical properties of PVP-MSA complexes were plausibly investigated for the first time. The complexation behaviors of both plasticized and unplasticized polymer electrolyte systems were confirmed with the aid of Fourier transform infrared spectroscopy. The conductivity values were found to be enhanced due to the addition of DMC, and a maximum value of 3.27 × 10−5 S/cm was achieved. The ionic transport number values were found to be in the range of 0.96–0.99. The discharge analysis suggested that the proton battery constructed with the plasticized polymer electrolyte showed better performance compared to that constructed with the unplasticized polymer electrolyte, which in turn means it could be utilized as a promising candidate for primary proton batteries.
