Method, equipment and storage medium for determining parameters of orthotropic slab of steel box girder

Abstract

The embodiment of the invention discloses a method, equipment and storage medium for determining parameters of an orthotropic plate of a steel box girder, wherein the method includes: obtaining the performance index name that the orthotropic plate of the steel box girder needs to meet; Describe the sensitivity of the structural parameter value of the orthotropic slab of the steel box girder, select the target parameter name from a plurality of structural parameter names; construct the conversion relationship between the target parameter value and the performance index value, and use the performance index value as The objective function of the independent variable; according to the conversion relationship and the objective function, the genetic algorithm is used to determine the optimal parameter value within the value range of the objective parameter. This embodiment makes the optimization result more in line with the actual engineering, and effectively improves the bridge performance.

Description

technical field [0001] Embodiments of the present invention relate to the field of bridge design, and in particular, to a method, equipment and storage medium for determining parameters of orthotropic slabs of steel box girder. Background technique [0002] Orthotropic slabs have the advantages of light weight, co-bearing with the main beam, and wide application range, and are the main structural form of stiffening beams for long-span bridges. Among the long-span suspension bridges and cable-stayed bridges that have been built or are being built across the sea and rivers in my country, most of them have adopted the structural form of orthotropic steel deck steel box girder. [0003] In the prior art, when the structural dimension design of the orthotropic plate steel box girder is carried out, the names of the structural parameters to be adjusted are usually determined by random methods, and the parameter values ​​are also determined by random attempts, which are not very ta...

Problems solved by technology

[0003] In the prior art, when designing the structural dimensions of orthotropic plate steel box girders, the name of the structural parameters that need to be adjusted is usually determined randomly, and the parameter values ​​are also determined randomly, which is not pertinent and cannot be accurately improved. Performance indicators that steel box girders need to meet
