The study includes estimation of seismic hazard, site characterization, site specific response analysis and risk assessment. Seismic hazard is performed based on deterministic and probabilistic approachs considering seismic sources influencing Jakarta. Geotechnical parameters are intrepreted from previous and recent measurements and depth of engineering bedrock is estimated based on microtremor array measurement. Identification of local site effects is conducted by carrying out onedimensional ground response analysis considering the behavior of soil non-linearity. The result of the hazard microzonation study includes the distribution of site response such as spectral acceleration and amplification ratio. The results are then combined with building fragility that is determined based on the FEMA 154. Two building fragility curves are formulated corresponding to existing building type in Jakartawhich are the confined masonry and in-filled frame structures. © 2015 Taylor & Francis Group, London.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Amplification ratio,Disaster preparedness,Geotechnical parameters,Ground response analysis,Hazard mitigations,Response analysis,Site characterization,Spectral acceleration[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
