英文摘要	To investigate the progressive collapse resistance mechanism for H-beam-concrete-filled steel tubular(CFST) column connections with inner-diaphragmjoints, a finite element model(FEM) for two half-span joint under the middle-column removal condition was established using ABAQUS. The displacement control loading method was used in FE andysis. The resistance capacity curves, failure modes and resistance mechanism curves of joints were calculated. The parametric analysis of H-beam-CFST column connections with inner-diaphragmjoints was conducted to find influence laws of different parameters, such as, beam strength, tube strength, core concrete strength, inner-diaphragm strength, steel ratio of column, thickness and width of inner-diaphragm, and span-depth ratio on joints' anti-collape capacity. The results indicated that the joints' failure evolution modes develop from beam flexural stage to catenary stage and damaged stage ultimately; increasing beam strength and decreasing span-depth ratio can obviously improve joints' resistant collapse capacity, increasing inner-diaphragm strength, width and thickness can reduce their resistant collapse capacity, and other parameters have no obvious influences. © 2016, Editorial Office of Journal of Vibration and Shock.
