In recent decades economic growth and urbanization has brought about development of massive amount of high-rise structures which has imparted lack of plain region for development of Structures, which initiates requirement for construction on slanted ground. The main objective of this study is seismic behavior of the G+5 building orientated with respect to the propagation of seismic wave up to 90⁰ ( i.e. 0⁰, 10⁰, 20⁰, 30⁰, 40⁰, 45⁰, 50⁰, 60⁰, 70⁰, 80⁰, 90⁰) to the building in Global direction, resting on the gentle sloped surface by considering the plain ground to Sloped ground up to 14⁰ slope. i.e. 0⁰, 2⁰, 4⁰, 6⁰, 8⁰, 10⁰, 12⁰ and 14⁰. The method of analysis carried out in this study is Response spectrum analysis in STAAD Pro.  The seismic parameters such as Base shear, Natural frequency of building and top story drift values are computed for Zone

Environmental systems can be realistically described by mathematical and numerical models of the system dynamics. These models can be used to predict the future behaviour of the system, provided that the initial states of the system are known. Complete data defining all of the states of a system at a specific time are, however, rarely available. Moreover, both the models and the available initial data contain inaccuracies and random noise that can lead to significant differences between the predicted states and the actual states of the system. A variety of models is used to describe systems arising in environmental applications, as well as in other physical, biological and economic fields. These range from simple linear, deterministic, continuous ordinary differential equation models to sophisticated non-linear stochastic partial-differential continuous or discrete models. The data assimilation schemes, with minor modifications, can be applied to any general model. Data assimilation schemes are described here for a system modelled by the discrete non-linear equations
