Development is a non-stop process it is seen that nowadays the development has reached to a new level. Thedevelopment doesn't mean construction in the sphere of civil engineering or architecture but the way has changed alot of definition of development itself. The serviceability, durability, safety, innovation in design etc. are lot morethings to be concerned. The design approach has now gone so far in the field of advancement in the use of softwareanalysis. Since, the complex structures and

... ti-storey structures cannot be solved with ease manually the help ofmore detailed and dynamic analysis has helped to solve such structures. Nowadays demand for aesthetic,modernization and urban growth cause to design complex structures with lots of plan and vertical irregularities. Thestructures in seismic zone are also the part of complex design so it is important to study more into the detail to gomore into the concept and derive more calculative and conservative solutions.
