Because numerous mega-columns and mega-beams of mega-frame are thin-walled beam, hence the torsion can' t be neglected in structural calculation, and so in the calculation of structural overall stability, the coupling of bend and torsion can' t be neglected .
Some problems of applying the software of structural computation and analysis in structural computation and design are discussed from rightly using programs,analysing and judging calculation results,and manually adjusting calculation results.
The structure optimizes the partial research technique is defers to the structure standard to carry on the structure computation, at the same time transforms the method using the matrix ship which unifies, carries on the 3000t level barge the structural design, the science objectively carries on the analysis, the comparison, the optimization, the appraisal to the 3000t barge structure, obtains the best structural style.
Owing to functions dispersion and low automatization level existing in application of CAD software,the integration technic has been adopted,and there developed the computer aided design system in integration(IBECADS)which possesses various functions as data management,modelling design,structure computation,analysis-checking calculatioun,drawing,statistics of engineering quantities,cost estimate,design file sorting out as well as other aided design tools.
Although the quality of results can still be improved, this shows that CP technology can greatly reduce computation time, a major advantage because structural NMR technique generally demands multiple runs of structural computation.
Ab initio structural computation provides crucially important theoretical input, through which experimental data can be analysed and interpreted.
Such structures could be declared meaningful by researchers, but in principle could also be identified by agents through structural computation.
The actual structural computation is then performed with the macroscopic model only.
The paper concentrates on the structural computation, and on issues affecting the accuracy of the deflected form passed to the aerodynamics code.
