( Faculty of Civil Engineering and Arclutecture, Kunming Uruversity of Science and Technology, Kunming 650224, China)Abstract: Some different structure forms were simulated by changing parameters of 18 concrete-filled steel tubular (CFST) IMS systems with flexible supports, including thickness of steel pipes, diameter of tie rods and simultaneous variety of both of them. A few kinds of structure forms that can resist the 8-degree earthquake and meet the requirements of performance were provided by analysis of Push-over method, which can be used for rehabilitation and reconstruction of buildings after efuthquake.
