| Abstract | In order to design and construct earthquake resistant structures at a location, estimation of seismic parameters and expected seismic movement are essential. Seismic movement in itself has been an unpredictable terminology in the past and in the present we only have been able to understand the patterns related to it. The seismic movement generally is described in terms of peak ground acceleration, spectral acceleration, amplification and period and it is visualized by us in terms of its effects on structures which we call response spectra. A simplified method of understanding ground response can be carried out by one-dimensional numerical analysis. Input parameters for the modelling in general would be soil profile, bedrock level, shear strength and most important a seismic movement data. If the movement data used had affected the location in the past, then the output analysis can be much more reliable and realistic for the location and also comparable to the real data. In most condition the parameters are unavailable or not viable but in this case due to the recent earthquake that affected in Kathmandu Basin as the study area, at least we have some realistic inputs for the seismic analysis acquired from the seismological stations in the basin. Thus, here use of numerical modelling and real input data has been done for analysis of ground response and sensitivity in order to estimate the probable amplification in output. Furthermore, as mentioned in the objectives of this thesis, it is to compare the generated microzonation map with the real microzonation data to compare the accuracy of analysis and damage assessment. |
