Abstract


The main content of this paper is to produce concrete beams and columns PKPM series software computer-aided design program, to complete the construction drawings CAD system for concrete beams and columns. Concrete beam-column construction drawings CAD system is a subsystem of the China Academy of Building Research Institute PKPM series software, it concrete beams and columns Reinforcement Computing, to complete the mapping of the different types of construction. In this paper, the 2004 and the previous version PKPM software beamed construction drawing module, fully learned PKPM Series software development team accumulated experience in programming practice. On this basis, the beam-column construction drawings CAD system to the overall design and modular design, the system data structures and modules relationship, in the CFG graphics platform using C and Fortran mixed-language programming, the successful development of concrete beams and columns construction drawings CAD system. The subject completed work includes the following: 1) the completion of the beam-column construction drawing software needs analysis taking into account the coordination with the other programs of the PKPM system to determine the software structure Ministry of PKPM works independently developed CFG graphics platform. Taking into account the advantage of the the COM standard in scalability maintainability, determined using COM components to complete the development of the common functions such as operating the table. C and Fortran languages ??need to use in the CFG graphics platform development program for mixed-language programming, requirements analysis part of the C language and Fortran language features are analyzed, and discussed the main achievement of the main points of the mixed-language programming techniques, and also on the The COM technology brief description. Needs analysis part of the study the structure detailed structure design processes and characteristics, and on this basis, the analysis of the functional requirements of the software. 2) Based on the results of the needs analysis, the function of the system design, module design and data structure design in the software design process, this paper analyzes the characteristics of the organization of the 2004 and previous versions of PKPM software module, according to the features of the software, the original dispersed construction drawing module integration components merge, reinforcement calculation, drawing four modules of the construction plans and user interaction. On this basis, to complete the design of data structures, to determine hierarchical data storage and processing programs used in the program. 3) complete the overall reinforcement calculation module design and development of reinforcement calculation module integrated in the 2004 edition PKPM system the planar reinforcement calculation module and facade reinforcement calculation module instead of the original design for the reinforcement of the component object for construction drawings reinforcement design development. Various construction plans share a unified reinforcement data, to ensure the consistency of the contents of the different manifestations of the construction plans. The reinforcement calculation module of Concrete Members computational requirements of the specification and construction requirements development, reinforcement system parameter settings, allows the user to flexible control procedures selected tendons. 4) Complete drawing construction drawing module and user interaction module optimization design of beam-column construction drawings CAD system to construction drawing system and user interaction system is organized on the basis of flat construction method shows the user directly on the flat construction method Figure reinforced modify the selected member of the operation of other types of construction drawings, simplifies user operation. Construction drawings module is fully developed in accordance with the relevant standards of the Architectural Drawing Standards and other countries, while using the parameter control, automatic layout technology, construction drawings generated higher degree of standardization, in line with the requirements of the engineering staff. Beam-column construction drawings CAD system user interaction module developed based on event-driven interactive platform. The interactive system uses the MFC-based architecture design, friendly interface, support custom toolbar common interface elements, the command can be executed in accordance with user-customizable interface, to meet the needs of different users. Through a large number of user testing and practical application of the system to achieve the desired development purposes, to meet the actual needs of most users.
