文摘

The multi-scale model was used to investigate the collapse performance of joints. The nonlinear static and dynamic analysis method were been used for analysis. There are 4 phases of resistance mechanism of joints to resist collapse. The catenary mechanism plays a vital role in the resistance of progressive collapse. Joints should have a strong connection between the steel beam and CFST column.
