Reliability Analysis On House Structure System Of Square Steel Tube Concrete Post And Girder Steel And Key Tube

By analyzing"A studying about the modern house system of steelconstruction on the middle and senior level", and in consider with a largenumber of experimental study and theory, the following conclusions aregot in this thesis. Firstly, a large amount of experiment work was carriedto the combining structure house of the steel - the concrete, such as itsmechanics performance and whole experiment and loading characteristicof whole structure and Supported with consuming energy , shakesperformance of the pilot project. The result of experiment shows that thissystem has excellent system of structure,the ability to resist earthquakeand concussion is strong. Secondly, two approaches of reliability of steelstructure houses were put forward. They are Research self-adaptationimportant sample law that combined whole circle sample and computingtechnology of reliability of fuzzy interval that base on Riemann integral.The first method makes computational efficiency of digital characteristicof sample density function improved by a large margin. In addition, theideal position of sample density function and the result of calculation offailure probability can be received,consequently the goal of improvingMonte Carlo method computational efficiency was achieved. And thismethod can be used in researching and developing the large-scalestructure system. Thirdly, By using the second method, how to fullyutilize the existing design materials and data to analyze the reliability ofsquare steel tube, with the aid of the designer's experience and judgementwas discussed preliminarily. In the analyzing of reliability by using thefuzzy message, how to express it in the fuzzy message has been discussedfor reference of fuzzy design. This method was applied to the reliabilityanalysis of the square steel tube concrete post successfully, in this thesis.天津大学研究生毕业论文(申请博士学位) 英文摘要Finally, Square steel tube concrete-Girder steel-The key tube structurehouse system is a complicated structure system, which includes manykinds of materials , such as steel tube concrete , girder steel , steel boneconcrete ,etc,rigid node and articulate node. This thesis has put forward acomputing technology of revised pole and equivalent nodal strength ofrigid frame-Truss mix structure system. Base on that, the analysedprocedure of finite element have been written. This procedure can solvethe reliability problem of systems, which is made up of many kinds ofmaterials and includes rigid node and articulate node, under various kindsof function of loading. And the suitability and the accuracy of the methodhave been proved through the instance.
