ETABS is a Design and Analysis software which is used for “Extended Three Dimensional Analysis of Building Systems”. This software is useful in the design of high rise multi-floored building in a systematic manner. In this study we considered (G+7) Residential and Commercial building, where in we need to Analysis all the design aspect and Stability condition of building in natural calamities. ‘Design of Precast Structure Using ETABS Software’ presents the design of multi storey building. The main aim of this study is to analyze the behavior of the precast structure for the applied loads. For this assignment we are using the software that name is ETABS it is an engineering software that completes multi-story building analysis and design. Code based load prescriptions and analysis methods or solution techniques, all coordinate with the type of grid like geometry unique to this class of structure. Either Basic or advanced systems under static or dynamic conditions evaluated using ETABS. when we start any building construction first we make a plan using by Auto CAD software doing the installation of beams and columns, testing of the stability of the building. to analyze the project ETABS software has been modeled to analyze the project.
