Abstract

In this paper an attempt has been made to explain computerised design with the aid of a simple illustration. The illustration has been so prepared that it exposes one to the hazardous design made by the computer when the design logic fed to it is a little bit erratic. In conclusion, it has been clearly shown that a computer is no substitute for a designer and the apprehension that due to computer aided design the role of designer is waning is absolutely baseless.

Abstract

The computer aided analysis could be used for designing various types of skeletal and continuum structures giving triple benefit to the designers-reduction of design cost, time and accuracy of results. However, such application should be made systematically and carefully- Wild usage of computers without proper evaluation of the users' requirement and without certain inbuilt safety devices in the application packages, may result to the failure and consequent unpopularity of the method. This is particularly important because of the fact that design engineers in our country as a community are not yet fully exposed to the powerful tool of analysis- The authors in this paper have tried to highlight this with a particular example of a tower structure commonly used in wind mills, hereafter called'wind-tower.
