In the recent trend the multi-storey buildings is the most common word in the construction source, in these buildings the concept of open ground building (OGS) has taken its place in the urban environment due to the fact that it provides the parking facility in the ground storey of the building, as the cost of construction of this type of building is much less than that of a building with basement parking for retail or commercial use. These open ground buildings which possess storey that are

... nificantly weaker or more flexible than adjacent storey are known as soft storey buildings. Soft story's are subjected to larger lateral loads during earthquakes and under lateral loads their lateral deformations are greater than those of other floors so the design of structural members of soft stories is critical and it should be different from the upper floors.In the present study the structural behavior of building is investigated under different cases such as open ground compared bare frame, partial infill walls. Analyzing the structure (using the Program SAP-2000 V16) for various earthquake intensities and checking for multiple criteria at each level has become an essential practice. The linear method of Equivalent static and Time History analysis is carried over to find out the structural behavior.
