Abstract - As the use of steel building increases daily, it is crucial to create aesthetically pleasing structures that are also cost effective. Since no software is perfect, designers must rely on a variety of tools to create unique architectures, specific components, or connections. In this study, we'll create a PEB structure and assess its viability and simplicity using two distinct pieces of software, then compare the outcome.
Key Words: Software,designing,structure,BIM,steel,construction.
1. INTRODUCTION
Steelconstructionisgrowingdaybydayandit’simportanttodesignthestructureelegantlyandeconomically.Softwareisused todesignthestructureandhandcalculationiscarriedouttochecktheaccuracyofthedesign.Inmanycountries,it’simportant to check the integrity of design using hand calculation. There is various software in the market with each having certain capabilitiestodesigncertainstructuresmoreefficiently.Thereisvarioustypeofstructureandsomegeneralstructuresuchas concrete,steel,aluminum,andwoodstructureusedmoreoftenandcountrieshavedifferentcodesandregulationtodesign these structures. No software is complete and thus designers have to depend upon various software to design different structuresorcertainpartsorconnections.Inthisstudy,wegoingtodesignaPEBstructureandcheckthefeasibilityandease withwhichwedesignthesamestructureintwodifferentsoftwareandcomparetheresult.Wewillusethesameloadsand memberssizetodesignthestructure.Wewillcheckthequalityofthefinalresultsofthetwosoftware.
