| In recent the large spacial structural systems are being adopted to the novel stadiums widespreadly, these structural characteristic is the complicated load and construction difficulty, and the geometrical shape and boundary of long-span structrure are greatly different between the construction period and the normal usage stage, so the result according to the conventional analysis method may make the structure insecurity among the construction period, or make structure capability of the completed construction not meet the requirements of engineering design. The simulation and monitor of the structure construction process and the analysis of stability are important steps to guarantee safety in the construction course and the normal use in the future. Combined with the engineering of steel roof structure of Jiang Nan University stadium, it is carries on relevant research in detail in this thesis. The relevant contents are as follows:1)The caluculative analysis considering construction effect is studied by the use of FEM programme, the study illuminates the effects of the different constructing order and the stiffness temporary on the stress distribution and deformation of the structure.2)The monitor of the structure different construction process is carried by the common strain gauge and fiber grating.And the measuring results are compared with the results analyzed by utilizing FEM programme.3)Be based on the simulation and monitor of the structure construction process,it analyzes structural performance considering construction effect and puts forward a plan on the monitor under service stage.4)This thesis calculates the Eigenpair of Structures by the use of FEM programme, and calculates the stability of the structure by geometrical nonlinear full process analysis based on...
