Abstract:: Ping’an Financial Center in Shenzhen was selected as the project background, health monitoring and simulation study were carried out during the whole construction stage. The health monitoring in construction stage mainly included vertical deformation of the structure, stress of the key parts and load monitoring. The whole process of construction was simulated considering actual construction schedule and time-dependent effects of material. The finite element model analysis of structure was carried out. The results show that the cumulative vertical deformation is related to construction stage and structure height, and the cumulative vertical deformation of core-tube is larger than mega column. Construction compression presetting can effectively compensate the deformation of structure. The stress of structure gradually changes with the construction stage. The compressive stress of core-tube and mega column increase about 0.09, 0.11 MPa respectively when one storey of upper structure is built. The interstory displacement angle can satisfy the requirements of national standard under the action of measured loads, and the structure is in stable state during construction. The simulation results agree well with the measured data. The method proposed can provide reference for similar projects.
