Abstract


As the important structure building of the solar system of power generation, It plays an important part in the efficient of this system. and stability of the operation. Concerned its characteristic under static loads dynamic loads ,wind-vibration and earthquake is analyzed systematiclly in this thesis.First, combined with the technological requirements of the project and the document of the program selection site. The author established the finite element model of solar chimney, Considering the self-weight, the equivalent static wind loads, seismic load and other loads. I combine the most unfavorable load case, complete the processing of static analysis of the structure. and the modal analysis of it.According to the ground soil type, the author selected the three earthquake for the seismic dynamic response analysis of this chimney, obtaining the vibration characteristics of it. The author introduced the theory of the fluctuating wind, containing the spectrum of the fluctuating wind speed and the spatial correlation of fluctuating wind speed at different high. Focused on the simulation theory and two method of simulation of wind speed time, such as harmonic superpositon method and the linear regression filter method and its realization The author carry out the simulation of the chimney. in the computer.Based on MATLAB simulation platform, The author wrote a program to generate wind time list curve, which contains an average wind speed time series of turbulent wind .also calculate the fluctuation wind loads inputing to the model of the chimney. Complishing the dynamic analysis under the load of the fluctuation wind.
