Emphasis is placed on the verification of models and analysis results to ensure a safe and economic structure is obtained at the end of the design process.Įxample of splitting a frame into a series of 2D models This article explains the basics of common structural modelling approaches and describes the differences between various types of analysis. The design can be performed to British or European Standards. Modelling the real world behaviour of a structure is made easier by the use of full model generating software, with load generating tools enabling frame stability verification along with member checks. Increasingly sophisticated analysis methods continue to improve the accuracy with which the behaviour of structures can be predicted. Modelling catenary actions, cold formed member performance or grillage analysis - all these are now commonplace for structures, where hand analysis is impossible. There is a vast range of analysis tools offering speed, precision and economy of design 3-D, FE modelling, bespoke portal frame, cellular beam or plate girder design software are now widely available. Structural analysis is the process of calculating the forces, moments and deflections to which the members in a structure are to be subjected.
