| Abstract: | The thermal properties and thermo-mechanical constitution law of steel and concrete were determined.A finite element model for temperature distribution and mechanical analysis of high strength concrete(HSC) walls under fire was established using the software ABAQUS.The calculated results agreed with previous experimental results.Based on the finite element model,the stress distribution,concrete cracks and key influencial parameters of HSC walls at high temperatures were analyzed.The fire performance of HSC ... |
