Abstracts: Structural Engineering is a science which understands behavior of various structures under different loads, analysing and designing these structures to withstand any/all anticipated loads. Analysis of a structure is the study of the behaviour of the structure under different loads. There are three approaches to the analysis: strength of materials, the elasticity theory approach, and the finite element approach. Matrix methods are more accurate and they tend to get complex with more number of structural elements. Since the 1990s, specialist software has become available to aid in the design of structures, with the functionality to assist in the drawing, analysing and designing of structures with maximum precision; examples include AutoCAD, StaadPro, ETABS, Prokon, Revit Structure etc. The manual design of these structures can be done using limit state method. In this project E-TABS is used for the Comparative studies of multi-storeyed frame structures. Here the Analysis of G+6, G+9, G+12 and G+14 frame structures with shear walls at different positions are undertaken. This analysis is carried out keeping the location of the building in different seismic zones. E-TABS, a purely structural design based software, is a dedicated building analysis and design software with matrix analysis / finite element analysis capacity. The base shear, storey shear, sway, bending moment, shear force, deflection etc are analysed in these structures. The study of the detailed design of shear walls is commenced. Also the steel requirement of the above mentioned frame structures is finalised. The calculation results indicates that the building with shear walls in a particular position shows better results in base shear, deflection, storey shear, bending moment etc. Hence it can be assumed that the proposed method can provide results with satisfactory accuracy requiring significantly reduced computational time and memory.
