摘要
In order to produce efficient, reliable design and to avoid unexpected catastrophic failure of structures, the engineer must understand the behaviour of buckling of large span reticu1ated shell structures. The function and the feature of the Code DDJTJQ, which is a computer program for static and buckling analysis of complex structures using finite element method, and the Code PPTJQ, which is a pre-post processing of DDJTJQ, are briefly intro- duced. The system has been implemented on microcomputers. An engineering structure, whose thin plate, thin shell and beam are important components, with 2965 degrees of freedom and 655 max. semi-bendwidth is analyzed. The numerical results of global buckling of reticulated shell structure of Jinan Zoo which was designed by Jinan Architectural Designing and Research Insti- tute are given.
