| Abstract: | In this paper, the simplified calculation model was established, based on the deformation and moment-rotation framework curves of the beam, the column and the joint area. The model was used to predict the load-displacement behavior and moment-rotation characteristics of the CFT column to beam steel connection under low-cycle reversed loading. The procedure was implemented by Matlab program. The results from the simplified calculation model correct well with that from testing. This kind of simplified analysis is helpful to the design and application of the CFT composite connections. |
