Analysis of the structure characteristics of the high-rise building, through the instrument observation, obtains each observation point’s total of subsidence and maximum subsidence, found no settlement of building site. Using the fi-nite element software for structural modeling, modal analysis shows that the quality of structural system, the stiffness is more evenly distributed the structure of the torsional capacity to meet the requirements. The model input Tianjin wave, analyzes the dynamic characteristics of the model, the results showed that: structure below the middle and lower classes, with the building height decreases, the horizontal displacement of reducing the magnitude of the structure of the middle and upper classes, with the building height increases, the horizontal displacement increases, a lesser extent; frame - shear wall structure, shear walls there are substantial limitations in the bottom of the lateral displacement, compared with the upper structure of the lateral displacement limit capacity.
