Design And Implementation Of FEA Preprocessing Software About Building Structure Frame

FEA(Finite Element Analysis) is a numeric value analysis method which has been widely used in many fields. It especially suits to compute with programming. With several decades' developing of classical domain theory, numeric value computing methods and computer technology, the FEA software has developed quickly.Building structure FEA software is a CAE software specially used in building structure FEA. It helps building structure designers to analyze or validate the designed building structure accurately, quickly and directly. It is an important analysis tool in building structure analysis domain.In this paper, the design and implementation of the computer aided analysis and design of NAP building structure frame is introduced, which is the subsystem of The Software component of Building Structure Dynamic Design and Platform Industrialization which is funded by Chongqing Information Industry Bureau.Preprocessing is a necessary function of FEA software. Preprocessing software of building structure mainly supplies a way to create building model with graphic input, which can help users to create model quickly and exactly and can save the data of the structure by a file that can be read and analyzed by structure analysis module. The problems about design and implementation of building structure preprocessing FEA software are discussed in the paper.In detail, this paper studied the building structure FEA business domain and OpenInventor graphic technology, designed and developed a preprocessing software for building structure frame FEA, which is adapted software engineering concepts and regulations; After comparing with classical CAD system model, put forward the scheme that is mainly built up based on MVC architecture pattern and with software bus as its assistant, and divided system into some modules. Studied the system's dynamic interactive behaviors, used the enhanced state machine to create a math model for system interactive controls, and provided a implantation of this scheme; Taking system data characters into account, designed the system data model; Combining with software design patterns, designed and implemented the system.The Building Structure frame FEA preprocessing software discussed in this paper supports a way to create building structure frame model with 2D or 3D graph, provides a friendly human-computer interface,can create structure model which under earthquake...
