Stochastic Analysis Of Construction Process Of Guangzhou New Library

There is much uncertain error and factor involve in construction process of pratical engineering structure, and how to consider the uncertain factor in construction process analysis of structure has been very concerned by designers. Therefore, it is necessary to study stochastic analysis of construction process for structures. However, stochastic analysis research of construction process for huge complex structure is not yet mature, it lacks of better analytical methods. On the basis of random structure static analysis theory and simulation analysis finite element method of construction process for engineering structure, this dissertation proposes a set of huge complex structure static analysis method on construction process for huge complex structure, which is applied to stochastic analysis and reliability analysis of construction process for Guangzhou New Library.The whole work of this dissertation consists of four parts. The first part introduces the concept and the common analysis methods of random structure static analysis and the simulation analysis methods of construction process for huge complex structure. The second part introduces the perturbation stochastic finite element method and Monte Carlo stochastic finite element method, which are the most commonly used methods to random structure static analysis, an improved random structure static analysis method, Response surface-Monte Carlo method, proposed by our group. The third part of this dissertation does the simulation analysis of construction process for Guangzhou New Library using the forward analysis. On the basis of the former two parts, the fourth part of this dissertation combines with Response surface-Monte Carlo method and the simulation analysis methods of construction process for huge complex structures, and proposes a set of stochastic analysis of construction process for huge complex structures, which is applied to stochastic analysis and reliability analysis of construction process for Guangzhou New Library.The main conclusions achieved in this dissertation are as follows:(1) The construction process of huge complex structure relate to many uncertainties, it is an important direction in which stochastic analysis and reliability analysis of construction process of construction process for huge complex structure.(2) This method summarizes the Response surface method,Monte Carlo method and the huge complex structure bridge construction simulation analysis method, and it has the advantage of simplicity solution principle and less computing and can meet the engineering request entirely. This method is especially suited for stochastic analysis and reliability analysis of construction process for huge complex structure.(3) Regarding Guangzhou New Library as engeering background, conducting stochastic analysis and reliability analysis with Response surface-Monte Carlo method, a much good result is obtained,further checked the validity and the practicability of the method.
