Abstract

Predicting reinforced concrete (RC) framed structure resistance to progressive collapse as a result of column removal scenario has recently become a necessity in the design of such structures. Such removal leads to large deformations impairing the functional performance of the structure. To predict the progressive collapse resistance, most of the researchers have developed numerical models to simulate the behaviour of test frames. However, these numerical models are confined to the test frames and would need to be modified when simulating different frames. This study discusses the resistance of RC framed structure to progressive collapse due to column exclusion from the viewpoint of numerical modelling issues using fibre element approach. The numerical results using fibre element approach were compared with a reported database of ten test RC framed buildings. The study shows that developing a simple numerical model, as an alternative to destructive tests, based on the fibre element approach with few elements and properly selected model parameters to adjust can accurately predict the resistance of structures subjected to interior column removal with minimal computational time and effort, and can be utilized in lieu of performing difficult advanced geometric and material nonlinear finite element computations.
