Area of Intrest & Research:

1. Primary objective is RESEARCH, directed towards increase of KNOWLEDGE.

2. To Study the Near fault effects on the Building Response of a Region.

Overview:

In the past, during design/analysis processes of engineered structures, it was assumed that the foundation of structure was fixed to a rigid underlying medium. In the last few decades, however it has been recognized that Soil Structure Interaction alters the response characteristics of a structural system because of massive and stiff nature of structure and, often, soil softness. The effect of SSI becomes prominent for heavy structures resting on relatively soft soils such as nuclear power plants, high-rise buildings and elevated highways. In dealing with the dynamic SSI, one of the most difficult tasks is the modeling of unbounded media. Many numerical methods or techniques have been developed to solve this problem such as transmitting boundaries of different kinds. During the past decade, the major thrust of SSI research has been targeted to the understanding of pile supported structures to the seismic waves as there is an increased concern about the seismic vulnerability of bridges and bridge foundations.

Future Work:

We can see that large scale simulation of urban regions till today have not included source and path effects along with the building response in the region of interest. ( Refer fig - 1 )

So there is a need to study the near fault effects on the building response of a region considering source, propagation path and local site effects.

Computational Methodology:

Near fault effects on the building response of a region is studied using Finite Element Method by considering source, propagation path and local site effects.

To solve the simulation problem we are using Domain Reduction Method (DRM) In DRM simulations can be done in two steps

1. The regional ground motion simulation is uncoupled from the sub regional analysis that includes the detailed models of nonlinear soils, foundations, and building inventory. ( Refer fig - 2 )

2. A region of interest (ROI) is defined and the boundary conditions between the regional simulation and the ROI are handled consistently. ( Refer fig - 3 )
