The new state of Andhra Pradesh has identified the region spanning the Guntur and Krishna Districts for developing a new capital. The development of the core is proposed on a green field site in the flood plain of Krishna River on Guntur side adjoining the existing settlement of Amaravathi. Being a highly productive land, yielding three irrigated crops a year, land acquisition has been quite expensive for the state. As such, the urban design has considered compact with high rise developments. In view of the heavy investment involved in the development of the capital, it is imperative to plan and protect these developments from natural and manmade disasters. The project aims at evaluating the terrain Amaravathi region and carrying out the seismic response of multi-storied structures resting on different types of soils. Spatial database has been prepared to carry out integrated spatial analysis and to identify the vulnerable zones in the study region in the event of an earthquake. Terrain evaluation is carried out by creating various thematic maps for soil & rock types, and seismo-tectonics of the study area at a high-resolution scale. After obtaining details of terrain evaluation, geotechnical and seismic analyses are carried out when a similar multi-storied building rests on different soils. The base shear and displacement parameters are also worked out and compared with the results obtained when the structure is assumed to be fixed at the base. Based on the insights gained through the evaluation of these multiple variables, the responses of multi-storied structures to various seismic scenarios are evaluated. The results indicate the necessity to consider soil-structure interaction while designing structures particularly when it rests on loose soils. It can be concluded that structures resting on stiff soils or rock behave well than structures resting on loose soils during an earthquake.
