Spectral displacement (SD) of banda aceh’s soft soil for seismic vulnerability assessment

Soft Soil Seismic Design Spectra Including Soil-structure Interaction

Design spectrum is known as an essential tool in earthquake engineering for calculation of maximum (design) responses in a structural system. Soil-structure interaction (SSI), as a phenomenon of coupling of responses of a structure and its underlying soil, was explored after introduction of design spectra and has not been taken into account in developing a design spectrum traditionally. To cons...

Seismic Vulnerability assessment of concrete railway bridge using nonlinear analyses

Bridges, as an essential part of transportation system, play a special role in economy, politic and military all around the world. Serviceability of bridges is of high importance especially in emergencies, helping injured people and proportioning transportation after earthquakes. Earthquake regulation codes, normally suggest linear methods to conduct the analysis, and nonlinear analysis is bare...

A multipurpose method for seismic vulnerability assessment of urban areas

The present work outlines a methodological framework for “ordering” through progressive levels of analyses different evaluation models concerning the seismic vulnerability at urban scale, with respect to the possible final objectives: seismic scenarios, emergency or urban planning, as far as seismic mitigation or economical estimates. The research work has been developed within the URBISIT Proj...

Displacement-based Rapid Seismic Assessment Procedure for Building Structures

Seismic Vulnerability Assessment Methods for Buildings in Japan

The development of seismic vulnerability evaluation standards for reinforced concrete buildings in Japan is briefly reviewed. Damage statistics are shown to indicate that severe damage was observed in a relatively small percentage of existing buildings even after damaging earthquakes in the world. Therefore, a simple screening procedure is necessary to identify such vulnerable buildings out of ...
