| Research Abstract |
In order to investigate the progressive collapse behavior of steel structures subjected to exceptional loads such as explosion or collision, impact loading and/or static loading tests for the steel portal frame with three different types of beam-to-column connections were carried out. In addition, 3D elastic-plastic FE analyses were also performed. The validity of the analysis method was conducted by comparing the experimental results. Dynamic behaviors of steel frames under impact loading were experimentally and numerically investigated. Furthermore, a basic knowledge for effectively analyzing the progressive collapse behavior was obtained.
