Abstract
When the structure of the silo steel framework of concrete mixing station is designed, In most cases, the dimension parameters, shape parameters and position parameters of silo steel framework beams are changed as the productivity adjustment of the concrete mixing station, but the structure types of silo steel framework will remain the same. In order to acquire strength of silo steel framework rapidly and efficiently, it is need to provide specialized parametric strength computational software for engineering staff who does not understand the three-dimensional software such as PROE and finite element analysis software. By the finite element methods(FEM), the parametric stress calculation modal of the silo steel framework of concrete mixing station is established, which includes dimension parameters, shape parameters, position parameters and applied load parameters of each beams, and then the parametric calculation program is written with MATLAB. The stress equations reflect the internal relationship between the stress of the silo steel frames with the dimension parameters, shape parameters, position parameters and load parameters. Finally, an example is presented, the calculation results show the stress of all members and the size and location of the maximum stress, which agrees well with realistic cases.
Highlights
With the increase of the productivity capacity of the concrete mixing station, the silo in which the concrete materials are stored is getting larger and larger, and it brings increasingly extrusive the strength problems of the silo steel framework
The finite element method, which can be discover the internal relationship between the strength of silo steel framework with dimension parameters, shape parameters, position parameters and load parameters, is widely used in static and dynamic modal of framed structures and shaft structure [5, 6]
The dimension parameters, shape parameters and position parameters of members of silo steel framework are changed as the productivity adjustment of the concrete mixing station when the structure of the silo steel framework of concrete mixing station is redesigned, but the structure types of silo steel framework will remain the same
Summary
With the increase of the productivity capacity of the concrete mixing station, the silo in which the concrete materials are stored is getting larger and larger, and it brings increasingly extrusive the strength problems of the silo steel framework. There is no research material about building the parametric computational design of silo steel framework of concrete mixing station with finite element method and programed in MATLAB, which includes dimension parameters, shape parameters, position parameters and applied load parameters of each members. By finite element method (FEM), firstly is to establish a theoretical modal of the silo steel framework of concrete mixing station taking into account both load distribution and structure properties, including dimension parameters, shape parameters and position parameters of members of silo steel framework. An example is presented, the result show the stress of all members and the size and location of the maximum stress, which agrees well with realistic cases
