Abstract

Abstract

Considering the need of practical project design, a framework of simplified assessing method is proposed based on the calculation model and simulation techniques.The potential of structural collapse of single level frame is utilized to represent the potential of whole non-sway structural model and this simplification assumption is verified with simplified mechanical and finite element methods.Based on the principle of energy conservation, pseudo-static analysis method is also verified in evaluating the peak structural dynamic response when considering the slab membrane action.Finally the potential of the structural progressive collapse of CFST structure with joint is analyzed, in which no welding is necessary in construction field.The influence of concrete strength, reinforcement ratio of beam and the bracket length are also investigated.
- concrete filled steel tube,
- structural progressive collapse,
