Concern that the relative ease-of-use of computers can lure engineers into faulty modeling and potentially dangerous consequences has led a London group to create a set of considerations for engineers to keep in mind when applying software modeling tools.
Guidelines for the Use of Computers for Engineering Calculations is published by Institution of Structural Engineers. It was developed after the group recognized that the slowness of the old manual systems provided time for designers to think and rethink the basis of the models being used. The speed of modern software deprives them of that step unless they make a conscious effort to re-examine their approach systematically. The 47-page book book can be ordered at www.istructe.org.uk.
