The Study of Transformational Hollow Concrete Filled Steel Tube with Carbon Dioxide Ⅱ:Theoretical Study
摘要
Abstract
In this paper, the interior simulated carbonization depth of hollow concrete filled steel tube ( HCFST) with high pressure carbon dioxide is acquired by fimte element simulation. The simulated numerical values are very close to the formula calculated data. The finite element simulation and the deduced theory show the different changes of the simulated depth of carbonization under different temperature and relative humidity. According to the simulated carbonization depth, the numerical values of compressive bearing capacity of HCFST calculated are in well agreement with the experimental results. On the basis of the experiments, the theoretical formulas of compressive bearing capacity of carbonized HCFST have been obtained. Meanwhile, based on existing theories, the theoretical formulas of the carbonization depth of recycled HCFST have been given. The related research is of the first time at home and abroad, which is of innovative significance.关键词
