Comparative Structural Analysis for Multistorey Building

The use of computers for the analysis and design of structures has become a
standard practice in today's world especially in the design of complex structures, such
that space craft, aircraft, tall building, long span bridges, etc. As a result of standard
practice of computational design of tall building structures, there is a number of
software in the market for a solution of similar problem. However, there is no existing
comparative analysis among commercially available software for tall building design.
Therefore, this research aims to perform comparative analysis of different software. The
comparison was made in terms of efficiency, ease in modeling and economy of design.
Throughout this project, the structural members of a multistorey building were analyzed
using different approaches which are by manual calculation and chosen softwares:
ESTEEM and ORION. At first, the comparison was made to the building which was
subjected to only vertical loading. Then the building was simulated by dynamic loading
such as wind loading. Lastly, the result outputs from the comparison was used to
validate the efficiency of the chosen software in producing the most economical and
optimum structural design with respect to manual calculation. Based on the analytical
and structural design results, ORION software is found to be more superior to ESTEEM
software in terms of producing the most efficient, economical and optimum structural
design with respect to manual calculation.
