Reinforced Concrete Fasting Laminated Mesh Barrel Arch And Shell Of The Structure Of Research And Applications

Open—web sandwich floor is a structure made up by bar unit,beam column units and plate element,integrated three-dimensional structure of the space system,with the rapid development of a modern economy and science and technology,the Industrial and Civil construction need to be build more and more.In the current calculation means changing today, the analysis of the structure is not the problem,system innovation is an important direction of development.This paper is mainly about static analysis of Open—web sandwich of reinforced concrete arch-shaped network shell and tube-shaped structure.The main work are about the finite element analysis,the single-Pin Arch force performance analysis,the overall model of the static analysis,simplified method of calculation,and on-site engineering practice,study and experiment.Open—web sandwich reinforced concrete arch-shaped shell and tube-shaped structure has proprietary intellectual property rights.Compared with Steel Network shell from the fire resistance,durability,and heavy-duty roof(wind),stiffness and construction(assembly to resolve the shell structure of the template consumption),the significance of the issues is raised. Open—web sandwich floor is a structure made up by bar unit,beam column units and plate element,.Three-dimensional force,integrity,and has a good stiffness.Simplified calculation methods are used to the new structure.use of the existing building structure analysis software for reinforced concrete structure Network shell design.Use of the existing software(TAT) calculations,the general practice means:Using equivalence principle of the bending stiffness,Open—web sandwich Arch will be equivalent to a solid rectangular section Arch(Arch altitude of 600 mm,the width of the equivalent moment of inertia Conversion come).And indulge in safe,no considering the ribbed panels to work.This Open—web sandwich are simple analysis,reasonable calculation,the bearing capacity of roof structures, high safety reserves.The issue is put to use in the engineering practice successfully,the State Power Company Guiyang Survey and Design Institute of Fitness Centre project.Carries on the field test overall assessment vaulting structure to this new structure the design and construction quality reliability.
