Being in the mist of the computer era, it’s hard even to imagine the challenges faced in thernstructural world when such software did not exist. In this ‘time is money’ world reducing the timernfor analysis and design of a certain structure from months to seconds is a miraculous achievement.rnThis thesis is believed to make us even more appreciative of the technological era we’re inrnwitnessing the evolution of structural software.rnAlthough extremely useful in tackling routine and tiresome analysis activities in engineering,rnsoftware by no means shall be taken as replacement for engineers. The basic engineering inputs ofrnformulating models and applying engineering concepts and judgment at every step of the wholernanalysis and design process remain largely of the engineer’s task. In contrary to the overgrowingrn‘software worship’ practice in our country, engineers are to check software result validity.rnEngineers should also spend enough time in exploring features of engineering software withrnproper assistance from their respective manuals. Instead of wrong software adaptation habit of onernengineering firm from another, the software features have to be thoroughly investigated so as tornprefer one software over another for a specific task.rnThe other important issue which needs to be addressed regarding engineering software practice isrnthe widespread use of pirated software products. The result reliability of pirated versions is put tornthe test by running four different types of structural models on a licensed SAP2000 V-12 and arnpirated SAP2000 V-12 version. The results obtained showed small percentage differences whichrnmight suggest good “crack†quality for this particular package used. But this by no means shallrnjustify the use of pirated products for a number of reasons to be discussed in this thesis.rnThe above implementations are set to narrow the gap and building trust between the seeminglyrnrival so called “academic engineers†and “practicing engineers†by providing tangiblernfunctionalities and limitations of the structural software and evaluating the questionable validity ofrnusing pirated products.
