Abstract:

As a designer there is a concern over the complexity of analysis required by design specifications and building codes because it forces engineers into types of analysis for which many are not qualified. This shift to more complex codes, coupled with the proliferation of computer programs which are intended to handle the complex analysis, creates a dangerous condition. The danger lies in the fact that now engineers who are either untrained or inexperienced in three-dimensional second order analysis and design have a tool to complete the design. When complex models are required, the design office must have efficient and reliable methods of verifying the results of the analysis. Today 'approximate' models are being used to verify the results of complex 'accurate' models. A more productive method of dealing with verification is to eliminate errors in the complex 'accurate' models. In order to develop a verification procedure, errors can be grouped in two general categories, assuming the program has no bugs. One is input error and the other is an error in modeling.
