Seismic assessment of residential buildings using FEMA P 154 guide line and investigating changes in comparison to FEMA 2002, Case study: Bolvar Ferdos of Tehran city
Abstract:   (21 Views)

Introduction: Residential buildings are highly vulnerable to earthquake and Destruction of them cause high casualties and injuries. For this reason, seismic assessment of buildings is necessary prior to earthquake. One of the methods for seismic assessment of buildings is RVS.  Federal Emergency Management Agency in the latest guideline, has made some changes in the data collection form with a conservative approach for seismic assessment of buildings.

Methods: In this applied research, changes made in the data collection form of RVS, were identified and compared to former version. Using this form, seismic assessment of residential buildings of Ferdos neighborhood in 5th region of Tehran was performed.

Findings: In the newest version, The data collection form for seismicity region, are classified into five categories. Some factors such as building type, severe and moderate vertical irregularities, plan irregularity, built year and soil type have been used to determine the final score. Special changes in factors and their scores, are indicative of conservative approach for buildings assessment. Among 816 selected buildings, 557 newly-built buildings, have achieved acceptable score and some of them got less than cut-off score. All 259 steel (URM) buildings in this neighborhood, are vulnerable to earthquake.

Conclusion: Regarding the results of this research, many newly-built buildings should be further evaluated by a design professional experienced in seismic design to determine if, they are seismically hazardous.  reconstruction or strengthening of steel (URM) buildings is necessary as soon as possible.
