To correctly acquire steel strain and deformation of SRC during construction process, one SRC transfer storey used in ultra high connected structure is chose. By nonlinear finite element method and field measurement, research on steel beam strain and deformation of the SRC connected structure in the whole construction process is performed. Based on practical construction method, the numerical analysis model for the construction process is established. Combined with time-variation mechanics and nonlinear finite element method, construction mechanics of the SRC transfer storey is analyzed, considering temporary support and construction load in each construction stage. Meanwhile, the field measurement of SRC transfer storey is carried out, and then the comparison between calculate result and measured value. The results show that, calculate result tallies closely with measured value, the steel beam is in a low stress state in the whole construction process, and the deformation of SRC structure varies linearly. The conclusion is that, mechanical behavior of the SRC transfer storey in the whole construction process can be grasped by nonlinear finite element method, and also the reliability of such structures in construction period and service life.
