| The construction industry has always been an important industry pillar of our country.In recent years,due to the country's strong support for the construction industry,the construction industry has been rapid development.The rapid development of the construction industry has become more and more significant in the architectural structure.In the rapid development of building structures,people have higher and higher requirements for the form of the building structure and the performance of the building structure in the production and life.As people's requirements for the form of the building structure and the performance of the structure become higher and higher,some new types of building structures have been also emerged.These building structures not only have been greatly improved from the form of the building structure,but also have a great extent in the use of the materials of these building structures.Modern architecture has combined the development of these two aspects very effectively,resulting in a new type of architectural structure.Compared with the previous architectural forms,these new types of architectural structures undoubtedly have a great advantage These advantages are reflected not only in the appearance of the architectural structure,but also in the use of the building structure in normal production and life.Among these new types of architectural structures with great advantages,it is typical that the concrete-filled steel tubular column beam joints are widely used in practical projects.The content of this study is to study the process research and stress analysis of the circular-ring concrete-filled-column truss-ring beam joints.This study is based on a project in Handan City,Hebei Province,using related professional theoretical knowledge,assist ABAQUS finite element analysis software and PKPM architectural computer aided design software to calculate the internal forces of the structural structural joint members of the circular concrete-filled steel tube columns and the computer finite element calculation and analysis of the circular-ringed concrete-filled concrete columns and beams,thus,the stress of the circular-ring concrete-filled-column ring beam joint was analyzed.In terms of structural finite element analysis and calculation,we must make a new type of construction method for the joints of steel-concrete-concrete column-rings and the construction method of the pre-improved steel-concrete-concrete column-ring joints.The finite element calculation and analysis model for reinforced concrete column-ring beams with two different construction methods,through the PKPM architectural structure computer-aided design software to calculate the internal forces of the corresponding components,the structural loads applied to the corresponding structural components,then use ABAQUS architectural structure computer finite element analysis software to calculate and analyze the structural finite element of concrete-filled-steel-concrete column-ring beam joints,so as to obtain the construction method of circular steel-concrete-concrete column-ring beam joints that is more meaningful to practical engineering practice.The longitudinal steel-concrete column anchorage of the frame girder of the circular steel pipe concrete column and ring girder joints constructed in accordance with the normal concrete structure design and construction specification construction methods was also studied.The comparison of the longitudinal beam anchorage of the frame beam of the ring beam joint results in the characteristics and advantages of the improved construction method of the circular steel pipe concrete column cohesion ring beam joint.At the same time,the research on the process and stress analysis of the circular-ring concrete-filled-column girder and ring beam joints will not only be based on the improved construction method of the circular steel-concrete-concrete column-ring beam joints,but also the use of the ABAQUS structure finite element analysis software.The stress analysis of the circular-ring concrete-filled-column ring-beam beam joints was carried out.At the same time,the economic benefits brought about by the construction method of the new circular steel pipe concrete ring beam joint node and the social benefits of the new construction method should be analyzed in more detail,the construction method of the circular concrete-filled-steel tubular column-ring-ring beam joint is not only based on the stress analysis,but also the comparatively outstanding advantages in terms of the economic and social benefits of the actual project,and it has obtained outstanding advantages,the new round steel pipe concrete ring beam beam joint construction method can get a greater degree of understanding,so that the building structure designers and construction personnel can more quickly and more intuitively accept and use this new round steel tube concrete column The construction method of the ring beam node makes the construction method of this new type of circular steel pipe concrete ring beam node more widely used,and makes important and prominent contributions to the improvement and perfection of the design and construction method of the modern building structure. |
