| The mechanical performance of the structure in construction is much different from the Application Phase. Different constructive methods would produced different stress state. If the construction method is unreasonable, and the construction process is not controlled Correctly, they would caused structure accidents. So, based on the project of the gymnasium in Wu Han Sports Center, the dissertation researched the method of the simulation analysis and the monitoring deeply, the results obtained are very important for the design and the construction.Firstly, the dissertation introduce the analysis methods of design and construction monitoring for Reticulated Shell-string Structure, then elaborate the method of the numerical simulating, analysis one series of Critical Technique of the simulation method, utilizate Life-death element technique in ANSYS adopt backward sequence simulating stretching process of stay cable.On the Basis of analyzing the construction of the gymnasium in Wu Han Sports Center, made the Key working condition, simulated by the link 8,by the link 10 in ANSYS, Through analysis of the simulated result, Offer the theoretical foundation for making the method construction and formulating the monitoring programme.On the Basis of the result of the finite element simulation analysis, making the reasonable constructive method. The method is used to monitoring the lift-up process of the structure, monitoring tensioning of Pre-stressed. in the lift-up process of the central part, the bar stress has a little change range, illustrating the lift-up process is safe. Comparison between the simulated results and the measured ones shows that the two results have the same mechanism.The conclusions of the simulation analysis and the monitoring is significant in practice and theory, They would provided some useful references to the theory in design and the engineering in construction of the Reticulated Shell- string Structure. |
