Orthogonal grid numerical reinforcement method for cylindrically structured buildings

Abstract

The invention discloses an orthogonal grid numerical reinforcement method for cylindrically structured buildings, which comprises: determining the reinforcement rates, hooping rates, thicknesses of concrete protective layers and models of steel bars of the cylindrical structure with an annual cross section, irregular base structure and top dome structure of a cylindrically structured building by a non-rod system steel bar reinforced concrete structure reinforcement method; determining the radius of hoop reinforcement ring on a bottom cross section, the actual length of short steel bars of hoops and the longitudinal distance between adjacent hoops; mapping the hoop units and public joints on the bottom cross section upward layer by layer till the top face; longitudinally connecting longitudinally adjacent public joints on adjacent cross sections to form a steel bar grid structure; importing the unit information, node information and unit structure information of the steel bar grid structure into a three-dimensional geological geologic model or three-dimensional concrete model for calculation; and exporting the unit information, node information, unit structure information and stress information of the steel bar grid structure by using TECPLOT software to obtain the axial stress and stress nephogram of the steel bar grid structure.

Description

technical field [0001] The invention provides an orthogonal grid-type numerical reinforcement method for cylindrical structure buildings in hydropower projects, and belongs to the category of reinforcement and numerical simulation of non-bar system reinforced concrete structures in the field of civil engineering. Background technique [0002] Tubular structure buildings are a common form of underground caverns, such as surge chambers of hydropower stations, etc., which are often huge in scale and complex in structure. How to calculate reinforcement is a technical problem faced by engineers. The top of the cylindrical structure is generally a dome-shaped cap structure, the bottom is designed as an irregular base, and the middle is cylindrical, which has the advantages of reasonable force and saving concrete materials. Under normal circumstances, in addition to the initial shotcrete anchor support, underground caverns such as cylindrical structures need to be supported by rein...

Problems solved by technology

The simulation of steel bars as structural units is intuitive and meets the design requirements, but it is difficult to realize the simulation of the head-to-tail welding of stirrups, the welding or binding simulation of cross bars, and the detailed display of the force on each part of the bars. Researchers determine reasonable reinforcement scheme for barrel-shaped buildings brings inconvenience
