Abstract

Real existing structures are generally complicated in geometry that might make them unsuitable or difficult forthe analyses. Several assumptions or simplifications are usually made by the practitioners to make them simpler andmay be analyzed in ease. The assumptions and/or simplifications might make the analyses much easier; however,they might create some deviations from the true behavior of the structures, which are in fact, are not known preciselyto the analysts. The paper discusses some examples for simplifications in the analysis or the structural systems. Theexamples include the types of the simplifications, and the deviations that caused by them. The types ofsimplifications are in the case of material behavior, the geometry of the system, an in the case of connectivity of thestructural components. The results signify the importance of wisdom in the setting of the simplifications and theassumptions to make the analyses easier but with dependable results.

Abstract

The use of computer programming provides accurate and speedy analyses of structural systems. The accuracyand the speed of the analysis are due to the novelty of the computer, i.e., the speed in storing and retrieving large sizeof data, and the speed and the accuracy in the numerical computation. However, in old days, due to the limitedstorage capacities of old generations of the computers, and the use of limited main frame computers, used by somany parties, the efficient use of computer memory became an important issue. Moreover, the use of rented base ofcomputer time necessitated the efficient use of computer run time. The paper discusses the efforts to efficiently usethe computer memory and computer run times. These issues seem to remain important issues, even though to date,the tendency is to use of personal computers and laptops instead the use of rented main frame computers.
