Research On The Key Technology Of The Natatorium Of Ningbo Olympic Sports Center Design

With China’s economic level and the country’s comprehensive strength of the continuous improvement of the building not only as a functional needs of people there,to meet people’s basic functional requirements,more and more landmarks,to bring more beauty enjoy.In particular,it is said that the construction of stadiums,"China National Stadium"," National Swimming Pool " and a large number of sports venues class construction emerged,these buildings are the level of structural design of the progress of the results.These buildings are the level of structural design of our country continue to progress the results。The author of this paper is the chief designer of the steel structure of Ningbo Aotu Engineering Swimming Pool,tis project has the following characteristics: Large span、Space steel truss roof、Steel-concrete composite structure.It needs to carry on the refinement of the design.In this paper,the problems encountered in the design process,in-depth study,the main contents are as follows:(1)The structure of a complete design work,the design of the main contents include: Structural analysis of the overall and local internal forces;The performance of the structural components were designed;The stability of the upper steel structure is analyzed;The calculation results are helpful for the design and construction of the project.(2)The structure system of the steel girder-concrete composite slab in the fitness area of the swimming pool has certain comfort requirements due to the functional requirements of the fitness area.The composite floor itself also has some comfort problems,and needs to be meticulous.analysis.In the third chapter,the problem of floor comfort is analyzed emphatically.Through the finite element model,the acceleration response of the floor under different working conditions is obtained by using the time-history analysis method,and the structural system is made according to the American ATC standard.The performance of the comfort evaluation.(3)The finite element analysis of the joints is a good method for the detailed analysis of steel tubular joints.It is also often used in engineering,but in the process of application,because of ABAQUS or other common finite element software,in the interactive interface Has been greatly improved,but the establishment of the model is still more complex.In this paper,the second development of ABAQUS is done by using Python language,and the function of parametric modeling is realized by taking the finite element node of Chapter 4 as an example.And provides a reference for the solution and exploration of such problems.(4)The finite element analysis of the joints is a good method for the detailed analysis of steel tubular joints.It is also often used in engineering,but in the process of application,because of ABAQUS or other common finite element software,in the interactive interface Has been greatly improved,but the establishment of the model is still more complex.In this paper,the second development of ABAQUS is done by using Python language,and the function of parametric modeling is realized by taking the finite element node of Chapter 4 as an example.And provides a reference for the solution and exploration of such problems.
