“…Building codes are simplified tools and do not adequately represent any single earthquake event from a probable source for the site under consideration. Recently, it has been recommended [11][12][13][14] that in addition to the use of seismic codes, site-specific analysis which includes generation of strong ground motion at bedrock level and propagating it through soil layers and arriving at the design ground motions and response spectra at surface should also be carried out in the design of important…”

During past earthquakes, damages occurred to buildings located at soil sites are more compared to damages observed on buildings located at rock sites. Modelling wave propagation through soil medium helps to derive the primary and secondary wave velocities. Most of the time soil mediums are heterogeneous, layered and undergoes nonlinear strains even under weak excitation. The equivalent linear approximation with one dimensional wave propagation is widely adopted for modeling earthquake excitation for layered soil. In this paper, importance of local soil effects, the process of wave propagation through three dimensional elastic medium, layered medium situated on rigid rock, attenuation of stress waves due to material damping, equivalent linear approximation, the concept of one dimensional wave propagation, and a case study of one dimensional wave propagation as a part of site-specific ground response analyses for Delhi region are included. The case study brings out the importance of carrying out site-specific ground response analyses of buildings considering the scenario earthquakes and actual soil conditions for Delhi region.

Although excessive damage of torsionally coupled buildings situated on soil sites has been reported during past earthquakes, no site-specific study is available having depth of soil stratum above rock as a parameter. In this article, an Artificial Neural Network-based methodology to determine dynamic to static eccentricity ratio of torsionally coupled buildings is proposed. Twelve neural networks are developed using 648,000 patterns from the analyses of shear type single-story building models. The methodology is found to be appropriate to determine dynamic to static eccentricity ratio for multi-story uniform, non uniform framed, and shear wall buildings for site-specific earthquake.
